框架-剪力墙结构静动力弹塑性分析

Static and Dynamic Elastic-Plastic Analysis of Frame-Shear Wall Structure

基于退化三线性恢复力模型,建立了框架-剪力墙结构的非线性地震反应分析模型。采用非线性分析程序IDARC2D 6.1对三个典型的10层不同剪力墙数量的框架-剪力墙结构进行了地震反应分析研究,探讨了结构在几种侧向分布力下的推覆反应和在水平地震作用下的动力时程反应。计算结果表明,不同水平荷载分布模式对结构的推覆曲线影响较大,同时表明剪力墙数量的不同对结构的振动特性和地震反应均有一定的影响。

Based on retrogressive three-linear resilience model, the nonlinear seismic responses analysis model of the frame-shear wall structures is proposed. The seismic responses of three typical ten-floors frame-shear wall structures with different shear wall numbers under the earthquake were studied by means of IDARC2D 6.1, where the push-over responses of the structures under several kinds of lateral load distribution as well as nonlinear time history responses under horizontal earthquake were discussed. The computing results show that the different lateral toad distribution models have a big influence on the pushover curve of structures, and in the same time it also shows that the numbers of shear wall have some influence on the fundamental vibration characteristic and seismic responses of the structures.
