Abstract

A finite element simulation for experimental punching shear behavior of reinforced concrete slab is presented in this paper. The numerical simulation is based on previously tested 15 reinforced concrete model slabs. Finite element analysis of reinforced concrete slabs subjected to punching load is evaluated and results are compared with experiments. This study involves development of a nonlinear strategy which implements solution for a realistic description of the deflection, load carrying capacity and crack, pattern related to punching shear of RC slabs for several types of slab thickness, edge restraints, and reinforcement ratio. It has been shown that the load versus. deflection diagram and ultimate load capacity obtained from FE analysis closely match with the experimental results. Comparison of crack pattern of the slab also shows good agreement. It has been shown that using appropriate method and material for numerical simulation, significant benefit can be achieved using finite element tools and advanced computing facilities in obtaining safe and optimum solutions without doing expensive and time-consuming laboratory tests.
