Experimental Study on Punching Shear Behavior of RC Flat Slabs According to the Egyptian Code

Abstract

In this research six of reinforced concrete slabs samples were tested in laboratory. These samples have a model scale 1:5. The samples a flat slab with concrete dimensions 1000x1000 mm and with thickness 160 mm. they have a concrete square column with dimensions 150x150 mm. Some variables were considered the distance between flexural longitudinal reinforcement, the distance between shear reinforcement and the width of the stirrups. The results of the sample were compared to those estimated by the Egyptian and international codes. The results indicated that the strength of punching increased with increasing the flexural and shear reinforcement in experimental samples. These samples were simulated by using ANSYS 17.2. The theoretical results were verified against experimental results and it’s founded the theoretical results near to the experimental results. The results indicated that the strength of punching increased with increasing the flexural and shear reinforcement in theoretical samples; it’s the same in the experimental results.
