Experimental Research on Seismic Behavior of Double Skin Composite Shear Wall

Abstract:

A case study was made of Yancheng Radio and Television Tower to investigate about the variation characteristics of stiffness, failure mechanism and failure mode, seismic performance and ultimate load bearing capacity of double steel layer concrete composite shear walls with different construction forms under constant axial forces and repeated horizontal loading on the basis of 9 scaled test models. An analysis was also made of the influence of height width ratio, axial compression ratio, plate thickness, concrete strength grade of the wall on the double steel layer concrete composite shear walls. The test results show that the the double steel layer concrete composite shear wall can make full use of steel and concrete, which is a structural member with better lateral resistance.
