摘　　要：针对某高层框架-剪力墙结构,在满足建筑功能要求的基础上,设计了4种不同布置的剪力墙模型。采用有限元分析软件SAP2000的振型分解反应谱法,对上述4种剪力墙模型进行了抗震性能分析研究。对4种结构模型的剪重比、层间位移角、周期比等主要参数进行了对比分析。研究发现:针对高层框架-剪力墙结构,可在结构的中间及周边布置少量剪力墙,适宜布置在结构周边;中间及周边布置的少量剪力墙能够承担大部分剪力,并提供足够的抗侧移刚度;周边布置的剪力墙可以有效加强结构的抗扭刚度,减少地震作用下结构的扭转效应。上述研究成果可为实际工程中框架-剪力墙结构的优化设计提供一定的参考。Analyzing seismic performance of four different shear wall models,which are based on a high-rise frame-shear structure project case and satisfy the building functional requests first,in Mode-Superposition Response Spectrum Method by finite element analysis software SAP2000. By comparison of main parameters of the models,including shear-weight ratio,story-drifts and periodic ratio,this research draws a conclusion that,in high-rise frame-shear structure,the small amount of shear walls set at middle and edge bear most shear force,provide enough lateral stiffness,and that shear walls arranged at edges can effectively reinforce torsional stiffness of structure and decrease structure torsional effect under seismic action. The results can be used for reference to optimal design of frameshear structure in practical projects.
