Abstract

A strength model was presented to give the mechanical explanation of the punching phenomenon, and to predict the punching shear strength of the interior reinforced concrete (RC) slab-column connection without shear reinforcement. The model assumes that the punching shear force is resisted mainly by the shearing-compression zone of a critical crack section, and the punching shear strength is determined as the minimum load among the loads which are obtained by the intersection of the demand curve and the capacity curve of each given flexure crack. The crack corresponding to the punching shear strength is defined as the critical crack. The capacity curve is obtained by the layer model of shearing-compression zone based on the biaxial strength theory of concrete. The demand curve is defined by equilibrium of forces in slab sector. For verification, the developed strength model was applied to existing test specimens tested by other researchers
