The full paper is published on the CD proceedings, and the short version of 4 pages is published in the printed version of the proceedings. The abstract is the following:
Reinforced concrete one-way slabs subjected to concentrated loads are designed for shear by checking beam shear over an effective width and punching shear. Only a limited number of test data regarding the shear capacity of one-way slabs subjected to concentrated loads is available. To better evaluate the shear capacity of reinforced concrete one-way slabs, a series of experiments has been carried out on continuous one-way slabs (5m x 2,5m x 0,3m) loaded close to the support. The influence of the shear span to depth ratio is discussed. Conclusions about the influence of this parameter on the one-way shear capacity of reinforced concrete slabs and possible explanations for the difference with beams are provided. Test results are compared to the Eurocode provisions and a method to calculate shear capacity from the literature. A higher shear strength is found as compared to the Eurocode. As a result of these experiments expressions resulting in a higher theoretical shear strength for the design of one-way slabs under concentrated loads are recommended.
