Mechanism Analysis and Experiment Study on RC Composite Core Walls

Abstract:

Two 1/6 scale core walls specimens were designed，including a normal reinforced concrete core wall and a reinforced concrete composite core wall with steel truss. The experimental study on two core walls subjected to combined action of compression, bending moment, shear and torque, was carried out. Based on the rotating-angle softened truss model theory, this paper presents a three-dimensional model for analysis of reinforced concrete composite core walls with steel truss subjected to complex loading. Through the results of calculation coincided with the test well, this model can predict the ultimate strength of the load-carrying capacity of reinforced concrete composite core walls with steel truss, and provide a tool to obtain the entire load-deformation history.
