The major concern in flat slabs is the concentration of high stresses in the slab column connection resulting in punching shear failure of the entire slab system. Hence in the present study an attempt has been made to study and analyze the effect of edge column in a flat slab. A numerical investigation was conducted using the finite element software ABAQUS to evaluate their ability to resist punching shear in a flat slab. The nonlinear characteristics of concrete were achieved by employing the concrete damaged plasticity model in the finite element program. Linear and nonlinear analysis of edge slab-column connection was carried out for slab of depth 150mm and 200 mm. Remarkable reductions in deflection is observed when the depth of slab is increased. © IAEME Publication.
