Drift behaviour of lightly reinforced concrete columns and structural walls for seismic design applications

Abstract

This paper presents the findings of a research project investigating the lateral load drift behaviour of lightly reinforced concrete columns and structural walls. Such columns and walls are common in regions of low-moderate seismicity, and although their strength properties are well defined, the drift performance is less understood. A detailed and simplified model for predicting the load-drift behaviour of reinforced concrete columns and structural walls is described in this paper. The results of a case study example are presented and clearly indicate the dramatic impact that the axial load ratio has on the drift performance of lightly reinforced columns, particularly the significantly lower..
