Post elastic behaviour of reinforced concrete beam-column joints

Abstract

Three cyclic loading tests on interior reinforced concrete beam-column joints from plane frame and one from a space frame are described. Mechanisms of joint shear resistance are postulated and recommendations are made for the aseismic design of beam-column joints. The effect of joint behaviour on overall structural response to earthquake loading is considered. An analysis of reinforced concrete column sections subject to biaxial bending and axial load is presented. The effect of biaxial bending on the uniaxial bending strength of columns is considered.
