摘　　要：对一规则、对称的钢筋混凝土框架-剪力墙结构建立了三维空间杆系模型,分别进行了单、双向地震动输入情况下弹塑性地震反应分析,并对结构角柱位移、层间位移角、顶点加速度时程、顶点位移时程等进行了分析和比较.分析结果表明,双向水平地震作用比单向水平地震作用对钢筋混凝土框架-剪力墙结构的破坏要大,仅对结构进行单向一维动力分析,难以真实揭示结构在实际地震中的性能.The spatial model of element regular and symmetrical frame-shear wall structures is established,and the elasto-plastic seismic response of structures under uni-and bi-directional seismic excitation is analyzed.The analysis results,including maximum displacement of corner columns,maximum story drift,time-history curves of vertex acceleration and time-history curves of vertex displacement,are compared.It is found that RC frame-wall structures will suffer qreater damage under bi-directional seismic excitation than uni-directional seismic excitation.It is difficult to reveal the true seismic performance of structures under the actual earthquake only trough the uni-directional dynamic analysis.
