Extended Strip Model for slabs subjected to load combinations



My coauthors and myself recently published a paper in Engineering Structures, titled "Extended Strip Model for slabs subjected to load combinations". You can download this paper free of access charges until July 1, 2017 via this link.

The abstract of the paper is the following:
The loads that are used for the assessment of existing reinforced concrete slab bridges are the self-weight, superimposed loads, and distributed and concentrated live loads. As such, the shear capacity of reinforced concrete slabs under a combination of distributed and concentrated live loads is a topic of practical relevance. For slabs subjected to a single concentrated load, a plastic model for assessment exists: the Extended Strip Model, developed based on the Strip Model for concentric punching shear. A further adaptation of the model to assess slabs subjected to distributed and concentrated loads is presented in this paper. The proposed model is compared to experiments on slabs subjected to a single concentrated load and a line load. The conclusion of this comparison is that the Extended Strip Model results in a safe estimate of the maximum concentrated load on the slab, and that the method can be used for the assessment of existing bridges subjected to heavy truck loads.

I am Pranoti Kshirsagar and This is How I Work

Today, I have the pleasure of interviewing Pranoti Kshirsagar for the "How I Work" series. Pranoti was born and raised in Nagpur, India. After finishing her bachelors in technology in Metallurgical and Materials Science and Engineering, she moved to Germany. She holds a masters degree in Materials Science from the University of Stuttgart. Check out her website or follow her on Twitter.

Current job: Working on my PhD
Current location: Tuebingen, Germany
Current mobile device: Xiaomi Redmi Note 3 and Mi 4i
Current computer: Macbook Pro

Can you briefly explain your current situation and research to us?

I am developing a reliable and reproducible fabrication technique for integrating carbon-based materials into microelectrode arrays (MEAs) which are used in biomedical applications. MEAs are used to record signals from cells such as neurons. The focus of my work is on two wonderful forms of carbon: carbon nanotubes (CNTs) and graphene. Both these materials are extensively researched in the past two decades, although their entry in biomedical field is relatively recent.

My work is fairly interdisciplinary. As a materials scientists I produce CNTs and graphene out of thin air (read: gases in a vacuumed chamber), integrate into the MEAs and voila, the device is ready for the cells to grow on. Our biologists then culture either cardiac or neuron cells on my devices. If they are in the mood, my devices host retina slices. Goal is to record cellular activity from different kinds of cells and maybe in the future excite the neurons with laser and witness the information transfer.

So in a nutshell, I collaborate with chemists, physicists, neurobiologists, biomedical technologists and several other field experts.

What tools, apps and software are essential to your workflow?
I use a lot of machines for the characterization of carbon. A few of the common ones are the atomic force microscope, the scanning electron microscope and the Raman spectrometer. I use a bunch of software packages like MATLAB, Origin, Coreldraw and TeXstudio to name a few.

What does your workspace setup look like?

I work in the labs at my institute and also at the university. So far I have a office at the institute, home and soon will be getting a desk at university.

work desk

What is your best advice for productive academic work?
There are several pieces of advice I can offer. :D

Smart time management is the key. The quality of the work is more important than the quantity of the work. Always have a goal in mind when working on a project / report. Every once in a while take a step back and judge your work from a third person's point of view. It helps to have the big picture in mind.

Exercise of any kind is very helpful for both physical and mental health
. I am more productive and positive on the days starting with workout. Type of exercise can be of your choice jogging, gym, swimming, biking, yoga..anything that keeps you focused and pumped up. Make a schedule and stick to it.

Set personal goals. Try to be as independent as possible. Always work towards a goal. I set goals for every day, every week. Remember, big picture!

Take time off. Try to stick to working hours. Your brain needs rest. To be more precise, your brain needs to think of other aspects of life than work. Take at least a day off every week. If you worked on the weekend take a day off during the week. Go to holidays twice a year. It is very important to cut off from the lab and make a fresh start.

Treat yourself
. When you finish the task at hand on or before deadline, treat yourself. It can be as small as buying yourself a butter-brezel. If you like solo travel, do it. I treated myself with a 2 month long holiday before starting PhD.

How do you keep an overview of projects and tasks?
Each working day starts with making a plan and ends with updating the plan. Everyday I take a step back and look at the progress I have made. If the day is not as productive as expected, I invest more time in the project the next day till I am at par. It helps to prioritise the projects. Not every project needs attention on daily basis. Instead of writing email to colleagues I prefer to walk down the hall and speak about the work in person.

Besides phone and computer, do you use other technological tools in work and daily life?
All my machines are very dear to me. I need all of them at least once a week.

Which skill makes you stand out as an academic?
Perspective. Motivation. Drive. Science communication.

It is very important to have the right perspective. Many scientists are unaware of where their work stands in the real world. One of the main reasons for doing a PhD should be the passion for research. This is something I miss in the aspiring PhD students.

Motivation is often lost over the course of PhD. But one has to keep the spirits high. The experiments are bound to fail hence I always have a plan B. There is a plan B1 in case plan B fails. :D You should believe in the power of your results. This comes in handy when presenting at conferences.

Drive to make things work is essential. As a PhD student you are expected to step in and take control of the project. Don't rely on your supervisor / prof to solve your problems. Its YOUR PhD, not theirs. Try to solve issues yourself before approaching anyone.

Communicate your science
. It is very important for future collaboration. Take advantage of the available resources to attend conferences, seminars, workshops. You should be able to explain your work in 1 min. It is very important to engage an audience of experts from varied fields in your work.

What do you listen to when you work?

This is an interesting one. I always have my headphones with me. I listen to Indian music and several other artists around the world depending on the mood and work at hand. While writing I prefer Indian music as it is comforting. In lab the music ranges from Alela Diane to Dire Straits to Artic Monkeys, the list goes on. There is so much good music out there!

What are you currently reading?

It is a tad bit difficult to keep up with reading literature other than science papers. But I try. Last book I read was pretty intense so I am giving myself some time off now. The next book on the list is 'Alone in Berlin'. I read while commuting and before going to bed.

Are you more of an introvert or extrovert? How does this influence your working habits?
I am a very selective extrovert. My work benefits from this. At conferences and workshops I am more of an extrovert. This helps a lot with networking and communicating science. I love presenting my work in front of a diverse audience.

What's your sleep routine like?
I go to bed between 10 pm - 11 pm and wake up between 5 am - 6 am.

What's your work routine like?

I start work between 7 am - 8 am depending on if I was swimming or at the gym before. I work till 5 pm - 6pm.

What's the best advice you ever received?
Research isn't only lab-work it is also how you package your work and present it to the public.
Be aware that you are woman in science. You will have to go an extra mile every once a while to prove your worth, it's the bitter truth.

PhD Defenses around the world: A viva in linguistics at Cambridge

Today, I have invited Dr. Alison Edwards to discuss her experience at her viva. Alison is originally from Australia but has lived in Europe since 2005. She is now based in Amsterdam and is the author of English in the Netherlands: Functions, forms and attitudes. She has a PhD in Linguistics from the University of Cambridge, an MA in Applied Linguistics and undergraduate degrees in Journalism and German Studies. In addition to her linguistics research, Alison runs a translation and editing business and blogs at www.theroguelinguist.com. Follow her on twitter or facebook


The preparations for my viva were not entirely smooth.

In the UK the viva is a closed session, just you and your two examiners, an internal one (from your own department) and an external one (flown in from Germany, in my case). When my supervisor told me who my internal examiner was, my first thought was: how strange. She works on the history of French, whereas I work on contemporary English. Still, I went to the library and studied all her books.

But I’d got my wires crossed somehow – either my supervisor gave me the wrong name, or I just remembered it wrong – because the internal examiner turned out to be someone else entirely. I discovered this a few days before the viva. Luckily the point is to discuss your own work, not theirs.

The day itself was sweltering hot, which always comes as a surprise in England, and the viva was held in a tiny top-floor room with windows that didn’t open. My two examiners were behind a desk; I was perched on a seat in the middle of the room where I had to balance my piles of papers awkwardly on my lap.

But they put me at ease from the start – as at ease as you can be in a situation like that – by saying it’s good, it’s going to be fine, we’re just going to have a nice discussion.

The whole procedure lasted just under two hours. I have friends who were grilled for more than five, so I count myself lucky. Nothing extremely challenging came up, but then I was well prepared. I knew there were a few parts in the quantitative sections that might give rise to questions so I had practised answering those, and had brought typed notes with examples that I could walk them through.

Generally, I just tried to be friendly and speak calmly and thoughtfully. Like when answering questions during a talk, I think the worst move you can make is to be defensive.

At the end the internal examiner said: since summer is coming up and you won’t otherwise find out for months, we’ll be nice and tell you the verdict now. We’re recommending your thesis be accepted with no corrections.

It’s hard for me to describe how pleased I was! There are all sorts of possible outcomes, including accept with minor corrections, accept with major corrections, revise and resubmit, or ‘this is so awful we’ll not even permit you to resubmit’ (e.g. in cases of fraud). But accept with no corrections is very rare, so it remains one of the proudest achievements of my life.

Afterwards I dashed across the courtyard to the economics building where my then fiancĂ© was a postdoc, bursting with the news. Then we went into college – we were both based at King’s during our time in Cambridge – where some friends were waiting.

It so happened that another friend was having her viva in virology the exact same day, so we all popped sparkling wine at Bodley’s Court, where the college backs onto the river Cam. It’s possible that I jumped into the river, to the surprise of the tourists punting by.

About five months later was the actual graduation ceremony, which is a very solemn affair with lots of gowns and pomp. My parents were there from Australia, with my husband and my new parents-in-law from the Netherlands – we got married just a few weeks before, so it was a very special time for me.
That night we went to Evensong in King’s chapel, by the famous choir. As always it was beautiful and atmospheric, and I’ll admit that I shed a few tears recalling my first visit to Cambridge, as a backpacker so many years before, when studying in such a place was a dream that seemed so out of reach it was laughable. Cambridge will always remain very close to my heart.

I Am Jennifer Askey and This is How I Work

Today, I have the pleasure of hosting Dr. Jennifer Askey in the "How I Work" series, from EnergizedAcademic. Her goal as a coach is to help clients work through frustrations, blocks, and setbacks to optimize their productivity and happiness--whether inside the academy or outside. She also coaches people who are ready to see their currently successful academic careers grow and flourish. 

Her academic career has spanned a wide array of jobs, types of institutions, and research contexts. She has worked as an adjunct/sessional instructor, been on the tenure-track and achieved tenure (Kansas State University in 2010), and worked on temporary full-time contracts. She has been an academic office administrator, served on personnel committees and on university Faculty Senate. She spent two years developing new academic programs and working on cyclical program review and have shepherded new academic requirements through approval processes. She has seen the university from multiple vantage points and isfamiliar with both the problems and the potentials there for graduate students, faculty, administrators, and staff.


Her academic training is in Political Economy and German literature. She seeks to impower het clients to harness their own experiences to maximize their potential. She is working toward ICF (International Coach Federation) certification with the Coach Training Institute. 


General:
Current Job: sole proprietor and coach at Energized Academic
Current Location: Hamilton, Ontario
Current mobile device: LG4 android phone
Current computer: MacBook Pro 15" laptop, circa 2013, Acer Chromebook c 2016

Can you briefly explain your current situation and research to us?
I run a coaching business that offers productivity, coaching, and personal/leadership development services to academics (broadly defined). Instead of researching German literature of the 19th century, like I did in my professorial gig, I research paths in and outside of academia; research on positivity and habits, and small business stuff.

What tools, apps and software are essential to your workflow?
I use both digital and analog tools. I have modified the Bullet Journal set-up to work for me as sort of a long-range to-do list plus daily accountability tracker. I have a vast array of pens in many colours. My phone is 100% essential for meeting reminders, as well as mobility on skype or phone with clients. I use Dropbox and Google Drive to share docs with my clients; with the acquisition of the Chromebook, though, I find myself navigating more toward Drive and wish that everyone else did, too. I appreciate having all of our shared notes and records in one common space and the version tracking that both of these services provide.

Recently I've begun using Trello.com, a kanban-style workflow board online, to track issues and questions my clients and I want to cover, are currently covering, and have covered. It is also a way to keep our meeting notes in one spot.

What does your workspace setup look like?

I work from home, in a cozy corner of a refurbished attic.

What is your best advice for productive academic work?
Schedule your time well, give yourself hard deadlines, remember that the perfect is the enemy of the good, and don't let little things gobble up all your time. Hire a coach to optimize your productivity and focus on your values and goals.

How do you keep an overview of projects and tasks?
Trello boards and the Bullet Journal

Besides phone and computer, do you use other technological tools in work and daily life?
Not really

Which skill makes you stand out as an academic?
Well, I'm not a practicing academic at the moment but a lot of the skills I used in teaching and research apply to my current position as coach. I am an excellent public speaker and lecturer. I really listen to students and colleagues. I understand the big picture that comes into being at the intersection of a person's individual agenda and the university's mission.

What do you listen to when you work?

Instrumental/classical music, if anything.

What are you currently reading? How do you find time for reading?
I am currently reading Motorcycles and Sweetgrass by Drew Hayden Taylor and am listening to a murder mystery in the Danish Dept Q series on audiobook. Audiobooks are for dog walks; printed texts are for bedtime or family reading time (instead of TV!). I'm also reading Hey Ladies, Stop Apologizing to review for my professional blog; I fit that into my work day in fits and starts.

Are you more of an introvert or extrovert? How does this influence your working habits?
I am an extrovert. This definitely influenced my decision to become a coach, which requires marketing myself to people, reaching out to them, sharing my opinions and expertise, and--occasionally--pushing people outside of their comfort zones.

What's your sleep routine like?
In my fantasy life, I go to bed at 11 and get up at 6:30. The 6:30am time is proving to be a bit optimistic when I don't have transit to catch or a class to show up to.

What's your work routine like?
It is variable because my non-negotiable work times are when I have calls or meetings scheduled with clients. These vary from week to week, so does my routine then, as well. I try to fit in a bit of professional reading each day, and make time for physical exercise (walk the dog, yoga) and meditation almost every day. I answer a lot of email and keep up with book keeping and scheduling, which takes up a fair amount of time.

What's the best advice you ever received?
Know what a fulfilled and content life look like for you; know what your non-negotiable values are and use all that information to find the career, life partner, etc. for you.

Extended Strip Model for Reinforced Concrete Slabs under Concentrated Loads


In the latest issue of the ACI Structural Journal, my collaborators and myself have published a paper titled "Extended Strip Model for Reinforced Concrete Slabs under Concentrated Loads." This paper introduces the plastic design model for reinforced concrete slabs under concentrated loads close to supports that I developed in my PhD thesis (see also this post). Close to my graduation date, I talked to a Canadian colleague who was in touch with the original author of the Bond Model, and we started to exchange ideas on the model shortly afterwards. After a meeting at a conference a year later, and some additional research we fine-tuned some details of the model. Life as a starting faculty member left me with little time to continue working on this project, and only when I received an USFQ Chancellor Grant to finish the paper we started in 2013, I committed fully to finish this research project.

You can find the abstract of the paper her:

Typically, beam shear failure is studied by testing small, heavily reinforced beams subjected to concentrated loads, and punching shear failure by testing slab-column connections. Both cases are related to shear in slender, flexural members. For deep members, strut-and-tie methods provide solutions. One-way slabs subjected to concentrated loads close to supports, as occurs with truck load on slab bridges, are much less studied. A theoretical solution to this problem is found by modifying the Strip Model for punching shear into an Extended Strip Model, taking into account the strut between the load and the support. Moreover, the Extended Strip Model takes into account the reduction in capacity resulting from unfavorable geometric circumstances. The resulting capacities based on the Extended Strip Model and on the shear provisions from NEN-EN 1992-1-1:2005 and ACI 318-14 are compared to experimental results, showing the improvement and uniformity of results by using the Extended Strip Model.

PhD Talk for Academictransfer: How to initiate and build international collaborations

This post is part of the series PhD Talk for AcademicTransfer: posts written for the Dutch academic career network AcademicTransfer, your go-to resource for all research positions in the Netherlands.

These posts are sponsored by AcademicTransfer, and tailored to those of you interested in pursuing a research position in the Netherlands.

If these posts raise your interest in working as a researcher in the Netherlands, even better - and feel free to fire away any questions you might have on this topic!


When are growing into a position of becoming an independent scholar, an important element is to start new collaborations. You are no longer expected to work exclusively with your colleagues at your institution or with your former supervisor. You are expected instead to spread your wings and develop new collaborations.

Unless you are planning to shut the door behind you and work in solitude for the rest of your days, it will become necessary to reach out to colleagues worldwide who have skills that are required in certain projects. Initiating international networks and collaborations is also important for your publications: it is generally considered positive if you get the opportunity to publish with colleagues from different institutions.

So how do you initiate and build international collaborations? Do you buy a plane ticket to a colleague whose work you've read, and just barge into his/her office to make your colleague an offer for collaboration that he/she can't refuse? There's no need for such drastic ways, and there are a variety of ways indeed in which you can start working across institutions and across borders. Below, you can find a number of ideas to get started:

1. Reach out to colleagues
The colleagues you’ve met several times at conferences over the past years and had good talks are potential collaborators. If you have a chance to talk to one of your colleagues at a conference, propose to work on a topic together. Don’t be vague, but propose a topic that is of your mutual interest, that combines both your skills. Make sure you’ve read some of the work of your potential collaborator, so that you have a good grasp of what he/she has been working on recently. If you want to start small, propose to write a conference paper on a certain topic first, and then see where the results take you. If the collaboration is pleasant, you can consider to apply for funding for a joint project.

2. Reach out after reading a paper
If you’ve read an interesting paper, go ahead and reach out to the author to ask further questions. If the author proposes an interesting method, you can ask for supplementary material and suggest to implement this method to your results, and develop a publication together. You’d be surprised how often fellow researchers react enthusiastically. Don’t feel disappointed if the author gets back to you making it clear that he/she does not want to share additional thoughts and insights on the topic – if that’s the attitude of this person, you won’t have a good collaboration anyway.

3. Service appointments
An excellent way of starting international collaborations is through service appointments, and in particular through technical committees. As technical committees develop technical documents, you get the opportunity to publish these documents either as committee documents, or by working in smaller task groups. If you are in your early career, don’t let an opportunity slide to work on technical documents (provided that you have the time, and can deliver what you promised). Working in technical committees also gives you an opportunity to interact with colleagues from different institutions directly.

4. Apply for funding with colleagues
If you have a colleague at a different institution with whom you’ve worked previously on a smaller project (eg. a conference paper), or have worked together through a technical committee, and you know your working styles are compatible, you may consider applying for funding together. You can apply for example for a European Union project (depending on where you are based), for which international collaborations are encouraged, or you can apply for special grants that encourage international collaboration (inform in your institution about the possibilities). Working together on a larger project with funding will require some trips back and forth, which will intensify your working relationship.

5. Jointly supervise students
If funding is not an option, but your university offers exchange programs for your students (for example, to go do their bachelor’s thesis at another institution), you can work together by supervising a student jointly. You can propose a topic that is of mutual interest between you and an international colleague, find a student interested in the topic, and then send the student for a few months to your colleague to work there. You can then decide to replace the thesis or project by a jointly written paper, or develop a paper later on from the thesis or project (depending on the requirements of your institution).
