Abstract

Based on recent reconnaissance, the plastic hinge zones in D-regions of structural members are vulnerable to earthquake loading. These non-ductile reinforced concrete members are usually dominated by shear behavior due to inadequate reinforcement and low concrete strength. Based on the proposed strut-and-tie models for D-regions, there are two different types of concrete strut: the bottle shape and fan shape. The objective of this study is to propose an analytical model to evaluate the shear behavior of these two force transfer mechanisms in D-regions. With test verifications, this paper provides a rational analytical model to generate the lateral load-displacement curve for the simulation of the shear behavior of structural members under earthquake loading.
