Abstract

This paper presents a nonlinear finite element modeling and analysis of the punching behaviour of reinforced concrete footings. The foundation system was modeled using ANSYS software. Several experimental tests were collected from literature to support the software outputs. The deflection in the footing’s concrete has been studied, marking the cracking patterns under column, and computing the failure loads for each footing. The experiments results were compared with the finite element results obtained from the modeled footing. The results indicated that the punching behaviour obtained from the analytical model using ANSYS software give good agreement with the experimental data with conservative difference of about 10 percent. Also, results of column`s punching shear capacity, using a number of codes of practice, were presented in this paper and compared with both experimental and the finite element results.
