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…
Last Friday, students from the Civil Engineering department of Universidad San Francisco de Quito, competed in national concrete student competition of Ecuador. My two concrete colleagues and I were involved as tutors of the two groups of students, and I'm…
For those ACI members out there, I recently discovered that my lecture in the session on "Recent Developments in Reinforced Concrete Slab Analysis, Design and Serviceability" is available online.If you're a student in structural engineering, you should consider becoming an…
Our paper "Shear in One-Way Slabs under Concentrated Load Close to Support" is now available online at the website of the American Concrete Institute and will be published in the March/April 2013 version of the ACI Structural Journal.Getting this paper…
We’ve introduced Dr. Marwa Al-Ansary to you as a civil and environmental engineer, working for Shell on (amongst others) sulfur utilization in materials such as Thiocrete (a type of sulfur concrete).But what is sulfur concrete really, and why do we…
We’ve introduced Erik Schlangen as Professor “Experimental Micromechanics”. But what does that really mean, and where does he wants the research of his group to result in? In his own words: he wants their inventions to show up when you…
My TEDx Delft Salon talk is online!
I spend most of my time in the laboratory to destroy slabs - but before doing so, we first have to make our specimens.The slabs I'm testing are reinforced concrete slabs, which are cast in timber formwork in the laboratory…
Last week, I attended the fib Symposium 2011 in Prague, and presented some of my experimental results in the Friday morning session on Construction Technology. The full paper is published on the CD proceedings, and the short version of 4…
Last month, I presented a paper at the ASCE Structures Congress 2011. The full paper is published in the conference proceedings, as well as online in the ASCE library. The abstract of the paper is: When assessing the capacity of…
