One is composition of two bearing systems, including truss and core wall, the other is composition of two materials, including steel and concrete. Two 1/6 scale core walls specimens were designed，including a normal reinforced concrete core wall and a reinforced concrete composite core wall with concealed steel truss. The experimental study on the seismic behavior of two core walls subjected to combined action of compression, bending moment, shear and torque, was carried out. The load-carrying capacity, stiffness, ductility, hysteretic behavior, energy dissipation and failure mechanism of the core walls were discussed. The test results showed that the seismic performance of core walls was improved greatly by the concealed steel truss. 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 concealed 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 concealed steel truss, and provide a tool to obtain the entire load-deformation history.
