Comparison of Seismic Behavior of Super-Tall Building Structures with Different Type of Steel-Concrete Composite Shear Walls

The seismic performance of frame-core tube structures with steel plate reinforced concrete(RC) shear wall,RC shear wall with concealed steel truss,and traditional steel reinforced concrete shear wall are investigated respectively by conducting dynamic and static elasto-plastic analysis with the aid of structural analysis software Perform-3D.Influences of three types of composite shear walls on the dynamic characteristics,displacement responses,and seismic damage of the whole structure are investigated.The study indicates that the seismic performance of the structure with steel plate RC shear walls is the best and that of the structure with RC shear wall with concealed steel truss is better than that of the structure with troditional steel reinforced concrete shear wall.
