Seismic loads are simulated by reversed cyclic horizontal displacements with increasing intensity. The two slabs differ in the value of the constant gravity load and this is examined in terms of their failure mode. Both specimens are analyzed using the damaged plasticity model for concrete offered in the ABAQUS software. In this plasticity damaged based model, damage can be introduced separate in tension and compression simulating the stiffness recovery of concrete after cracking, specifically, when cyclic loading takes place. The numerical analysis results are compared to the test results in terms of moment resistance and crack patterns. Both FEA and experimental results are in good agreement indicating the effectiveness of the finite element model. Finite element analysis can give an insight into the failure mechanisms and crack developments of concrete slabs; creating a basis for future parametric studies on many aspects in punching shear of reinforced concrete slabs located in seismic zones.
