工业厂房框—剪结构弹塑性简化计算研究

The analysis of elastic-plastic simplified calculating method for frame-shear wall structure of industrial factory building

结合拟动力试验所得结构与剪力墙的刚度退化规律,推导出弹塑性阶段框架—剪力墙刚度比特征值及顶层位移的计算方法;并根据剪力墙底率先出现塑性铰的试验事实,提出了通过释放"多余弯矩"求解工业厂房框—剪结构在弹塑性阶段位移的简化计算方法及计算模型,可供第二阶段设计参考。

Based on the pseudo dynamic test study,the elastic-plastic frame-shear wall rigidity ratio and structural top displacement of the model is calculated according to the loss lows of structure and shear wall rigidity.Noting that the plastic hinges appeared bellow the wall in the test,a simplified calculating model is presented to calculate the displacement of the structure in elastic-plastic phase by releasing 'Superfluous moments',and takes a reference to the second phase seismic design.
