Experimental investigation on shear capacity of reinforced concrete slabs with plain bars and slabs on elastomeric bearings

My co-authors and I recently published a paper in Engineering Structures - this paper is our second paper in this journal. To better distribute the paper, Elsevier allows free access to the paper via this link until October 29th, 2015.

The abstract of the paper is the following:

One-way slabs supported by line supports and reinforced with deformed bars were shown previously to behave differently in (one-way) shear than beams. For the application to existing slab bridges, the influence on the shear capacity of using plain reinforcement bars and of supporting the slab by discrete bearings is investigated. To study these parameters and their influence on the shear capacity, a series of experiments was carried out on continuous one-way slabs (5 m x 2.5 m x 0.3 m), subjected to concentrated loads close to the support line. The results from these experiments are compared to code provisions and a method developed by Regan. These experiments confirm the findings that slabs subjected to concentrated loads close to supports have larger shear capacities than beams.

  1. Congratulations Eva!
    I would like to ask you what method are you using to reproduce the crack pattern (see Fig. 12 in your paper)

    1. Old school: taking the photograph, stretching it out so that it looks kinda flat in Illustrator, then drawing all the cracks by hand/mouse in Illustrator, then deleting the photograph and I'm left with the cracking pattern.

  2. OK, thanks. I'm using roughly the same method (photoshop and autocad) but I thought there might be an automatic way of doing it, i.e. some matlab script.

    1. Difficult I think, because the cracks don't show up as just "black" on the photographs. My super-matlab-automated colleague who was scripts for everything does this drawing part by hand as well (but he has scripts for flattening and straightening the photographs, which I do by hand, because I didn't draw grids on the bottom of my slabs)

  3. Hi eva... Its a useful information for me and i got detailed idea about it. Thank you so much for the share and i like to share this information in my website.
