水电站厂房框架—剪力墙结构抗震分析

Seismic Analysis of the Frame-shear Wall Structures of Hydropower Station

对某水电站厂房框架—剪力墙结构建立了有限元模型,并进行模态探讨和抗震探讨。利用ANSYS构建了一个对应的模型结构,通过振型分解反应谱法对结构进行了抗震计算,计算地震作用下结构的应力、应变。由计算结果可知,应力分布符合一般规律,结构刚度满足规范要求。

The finite element model of the frame- shear wall structure of a hydropower station is established, and the modal and seismic analysis is carried out. The structure of the model was constructed by ANSYS, and the structural stress and strain of the structure were calculated by the mode decomposition response spectrum method. From the results of calculation, the stress distribution accords with the general law, and the structural stiffness meets the standard requirements.
