| Abstract: | To improve the seismic performance of reinforced concrete core walls, reinforced concrete composite core walls with concealed
steel truss were proposed and systemically investigated. Two 1/6 scale core wall specimens, including a normal reinforced
concrete core wall and a reinforced concrete composite core wall with concealed steel truss, were designed. The experimental
study on seismic performance under cyclic loading was carried out. The load-carrying capacity, stiffness, ductility, hysteretic
behavior and energy dissipation of the core walls were discussed. The test results showed that the seismic performance of
core walls is improved greatly by the concealed steel truss. The calculated results were found to agree well with the actual
measured ones.
