| Abstract | |
This work reports experimental research of reinforced concrete flat slabs with use of shear reinforcement not embracing the flexural reinforcement. Eleven square reinforced concrete flat slabs with 200 mm thickness and 3000 mm side lengths, with a square central column of 200mm of side, were tested up to failure. The main objective was to investigate the efficiency of using the mentioned shear reinforcement. All slabs failed by punching and the ultimate loads were superior in up to 110% in relation to slabs without shear reinforcement, demonstrating the efficiency of the reinforcement. The numerical simulations using axisymmetric and three dimensional analyses, of reinforced concrete flats slabs, were carried out with the objective of reproducing some experimental results reported by different investigators, validating the experimental part and also the numerical modelling . The numerical simulations were performed with the software package DIANA, adopting the smeared crack approach to reproduce the concrete behaviour under shear and tension. The evaluated results were mode of failure, strain in steel and loaddeflections curves. (AU) | |
