Abstract:

In this paper,by analyzing the early-obtained preliminary experiment results of the composite steel-plate shear wall system with short-limb steel frame applied to mid-rise buildings,the composite shear wall constrained by angle steel and external precast concrete wallboard was selected as the research objective to further optimize the width-to-thickness ratio of the embedded steel plate as well as the boundary constraints of the external wallboard and of the steel plate. Moreover,some low-cyclic tests were carried out for the optimized structure. The results indicate that the shear wall system with proper structure can effectively improve the energy dissipation ability; and that,at the same height and span,the hysteresis curve of the system becomes fuller,and the ductility ratio.the elastic lateral stiffness,and the energy dissipation ability increase by about 7. 7%,49% and 62%,respectively.

Key words: steel frame, steel plate, shear wall, boundary constraint, seismic behavior, energy dissipation ability
