Moment Transfer by Shear in Slab-Column Connections

Moment Transfer by Shear in Slab-Column Connections

Abstract

A bending moment M u transferred at a slab-column connection is resisted at the slab critical sections by flexure and shear. The ACI 318-89 Building Code 1 and the Canadian Standard CAN3-A23.3-M84 2 give an empirical equation for the fraction γ V of the moment M u to be transferred by shear at the slab critical section at d/2 from the column face. The equation is based on tests of interior slab-column connections without shear reinforcement. However, it is used in the design of interior, edge, and corner connections. In addition, when shear reinforcement is provided, the shear stress must be calculated at other critical sections farther away from the column face. Studies using linear finite element analyses show that the code equation for γ V does not apply to all cases and to all critical sections. The paper derives equations for γ V to cover all of the cases and sections that need to be checked in design. Studies leading to the proposed equations are presented. Equations are verified using published experimental data.
