【摘要】 运用ANSYS12.0有限元程序对一带梁式转换层的框支剪力墙结构进行了研究分析。首先通过模态分析得到结构的动力特性;其次采用弹性时程分析研究结构在竖向地震作用下结构的动力反应及主要受力构件的内力。研究分析发现,在竖向地震作用下对于框支剪力墙结构转换梁相邻楼层结构形式发生变化的部位易形成薄弱部位。框支柱柱端承受的轴力较大易形成塑性铰,同时转换梁轴向受拉且拉力沿梁跨中向梁端递减。更多还原

【Abstract】 The structure of a frame-supported shear wall structure with the beam-type conversion layer was analyzed by the finite element program ANSYS12.0.The dynamic performance of the structure was obtained through a modal analysis and then through the elastic time-history analysis the dynamic response of the structure and the internal force of main components were researched under the vertical earthquake action.The results showed that under the vertical seismic action the part at which the floors were structurally transformed adjacent to the conversion beam of the frame-supported shear wall structure tended to form the weakest link.And the axial force of frame column tops tended to form plastic hinges,at the same time the conversion beam was drawn in the axial force direction and the pull descended from the midspan to the end of the beam.更多还原
