摘要:
为研究半刚性框架-密肋框格防屈曲钢板剪力墙结构的抗震性能，对一个1/3缩尺的钢框架-防屈曲剪力墙模型进行了弹塑性时程分析重点分析Taft波、E-Centro波及人工地震波作用下的动力特性、加速度反应、位移反应和剪力分布等．结果表明：多遇地震作用下，结构的刚度退化不明显；罕遇地震作用下，结构表现出强烈的非线性和明显的刚度退化；结构的层间位移角为1/1/149，均满足我国现行抗震规范对层间位移角限值的规定和三水准抗震设防要求．密肋框格的设置改善内填钢板的受力性能，并实现防屈曲的目标．研究为该结构的抗震设计及其在抗震设防区的应用提供参考．
Abstract:
A model specimen of semi-rigid steel frame with buckling-restrained steel plate shear wall, at the scale of 1:3, was investigated under the elastic-plastic time-history analysis to research the seismic performance of this structure. Taft wave, EL-Centro wave and an artificial wave were selected to focus on theirs dynamic properties, acceleration responses, displacement responses, and shear force distribution etc. The analytical results indicate that the stiffness of the structure degrades slightly under the frequent earthquakes, but degrades obviously under the rare earthquakes and shows strong nonlinearity. The maximum inter-story drift of the model during the frequent earthquakes and rare earthquakes is 1/1 016 and 1/149 respectively. Both meet the demands of inter-story drift limitation in the current Chinese code for seismic design of buildings and can satisfy the ‘two phase and three level’ seismic fortification requirements. The application of multi-stiffeners reaches the objective of buckling-restrained and improves the mechanical behavior of infill steel plate. The research will provide reference for seismic design and application in seismic fortification areas of this structure
