Unbalanced moments commonly occur in buildings with flat slabs, caused by unequal spans or loading on either side of the column. Differences of temperature or differential creep between two adjacent floors results in differential displacements of the top and bottom of the columns, which induce moments in the slab-column connection, even if the columns do not participate in the horizontal load resisting system. In the presence of such moments, the punching becomes unsymmetrical, and the punching strength of the slab decreases. This paper presents finite element analysis of slab-column connection in order to investigate the effect of eccentric load. Three-dimensional nonlinear finite element models had been created by the authors in order to simulate the behavior of the flat slabs which included the load-deflection response, the ultimate failure load and the crack pattern. The purpose of the present study is to quantify the effect of a moment on the punching load and to quantify the expected moments for typical configurations of internal columns in structures by using finite element analysis. Also the effectiveness of punching shear reinforcement in the presence of moment transfer has been investigated. Punching strength for slabs with various eccentricities according to provisions of different Standards for finite element models was investigated and its relevant results indicated that Canadian standard locates in a better safety zone. Also the effect of load eccentricity has been studied and indicated that eccentricity, would reduce the final load considerably.
