摘要
构造能模拟一层框剪结构的层单元,用振型分解反应谱法分析不同高度和结构刚度特征值的断层剪力墙框剪结构的地震反应,设定可中断剪力墙高度的条件。计算表明,可中断剪力墙高度的决定因素为上部框架的抗剪能力,随着刚度特征值的增加,可中断剪力墙的高度随之增加,给出了两者之间的表达式,结构高度对中断剪力墙高度的影响较小。
The storey element,which can model one storey of the frame-shear wall structure is fabricated.Based on SRSS method,the frame-shear wall structure with shear wall interruption at different heights is analyzed.The conditions of interruptable shear wall height are established.Calculation results indicate that the decisive factor influencing interruptable shear wall height is the shear force carrying capacity of the frame above shear wall interruption;the interruptable shear wall height increases with the increasing of the rigidity characteristic.The equation between the rigidity characteristic and the interruptable shear wall height is presented.The height of the structure has little influences on the interruptable shear wall height.
