Critical review of Canadian Standards Association standard CSA-A23.3-94 provisions for punching shear strength of edge column–slab connections

Abstract

The purpose of this paper is to critically review the punching shear strength provisions of the Canadian Standards Association standard CSA-A23.3-94 for edge column–slab connections. Tests from the literature and our own experiments are used to study the most important parameters affecting the punching shear strength of edge slab–column connections. Based on the test results the eccentric shear stress model is evaluated for edge column connections, and improvements are suggested.Key words: edge column–slab connections, flat concrete plates, shear strength, punching shear, shear reinforcement, moment transfer.
