On the basis of experimental research and theoretic analysis, the aseismic behaviour of 24 structures of frame and frame-truss with special-shaped columns is compared. The effects of frame-truss with different special-shaped columns on lateral stiffness and reaction of earthquake are discussed. Some advices for engineering design are suggested.
Keywords:  R.C.frame-truss;  special-shaped columns; earthquake resistant behaviour
