中文摘要：

提出了一种半刚性框架-密肋防屈曲钢板剪力墙,并对该结构进行了低周反复试验,研究了其滞回曲线、骨架曲线、延性及耗能性能.试验结果表明该结构具有较高的抗侧刚度、承载力和稳定的耗能能力.并在试验研究的基础上,通过ABAQUS对该结构进行了有限元模拟,在承载力、层间位移、破坏形式等方面与试验结果吻合较好.并且通过有限元模拟了非加劲、加劲板的弹性屈曲荷载,其模拟结果与理论值、《高层民用建筑钢结构技术规程》规定值接近,表明密肋的设置有效地避免了内填板的整体屈曲,保证了内填板剪切屈服先于弹性屈曲.该研究为其理论分析和工程应用提供了依据.

英文摘要：

This paper presents a semi-rigid connection with buckling restrained steel plate shear wall（BR-SPSW） using grid-stiffeners.Hysteresis curves,skeleton curves,ductility and energy dissipation of the structure are discussed by the low cyclic test,and the test results show that this structure has high elastic lateral stiffness,bearing capacity and stable energy dissipation ability.Based on the experiment,these results have also been analyzed by using ABAQUS,and the aspects such as bearing capacity,story drift and failure mode of the structure have better tally with test results.The elastic buckling loads of unstiffened plates and stiffened plates have also been simulated by finite element model,and the simulation results are consistent with the theoretical values and the specified values of technical specification for steel structure of tall buildings,which indicate that the setting of grid-stiffeners can effectively avoid the overall buckling of infill plates and guarantee the shear yield precede the elastic buckling.In the end,the research provides a basis for theoretical analyses and engineering applications of the structural system.
