高承载钢板剪力墙抗震性能试验研究

框架-阻尼框筒是以框架-钢板剪力墙代替框架-核心筒结构中的钢筋混凝土核心筒，通过钢板剪力墙提供阻尼和刚度，形成了新的减震体系。基于该体系在超高层建筑中应用需求，完成了2个足尺钢板剪力墙的低周往复加载试验，对比分析了剪力墙在循环荷载作用下的承载力、延性、刚度及耗能能力，并与相应有限元结果进行对比。结果表明，所提出的高承载钢板剪力墙具有优良的延性和耗能能力，屈服荷载和极限荷载分别超过3300kN和5500kN，满足相应抗震设计要求。同时，有限元分析结果与试验结果吻合较好，可用于后续钢板剪力墙的优化。

Experimental study on seismic behavior of steel plate shear wall with high load-bearing capacity

Frame-steel plate shear wall structure (SPSW) is adopted to replace the reinforced concrete core tube of the frame-core wall structure in the newly-developed structure system named frame-damping frame tube structure,which provides damping and stiffness through the steel plate shear wall. For application requirements in super high-rise buildings of the new structural system, low cyclic loading tests of two full-scale steel plate shear wall specimens were conducted, and the bearing capacity, ductility, stiffness and energy dissipation capacity of the specimens were studied and compared with the corresponding finite element analysis results. The results show that the proposed steel plate shear wall with high load-bearing capacity shows excellent performance in ductility and energy dissipation capacity. The yield load and ultimate load exceed 3300kN and 5500kN respectively, which satisfy the corresponding requirements for seismic design. At the same time, the FEA results agree well with the test results, which can be used for the subsequent optimization of steel plate shear wall.
