建筑结构空间整体的地震作用分析

提出了建筑结构在水平地震作用下的空间整体计算模型，并讨论了其计算方法。按该计算模型分析某电厂主厂房，计算结果与实测结果吻合良好。通过计算对比获得以下结论：（１）对于刚度和质量分布明显不均匀的结构，可选抗侧力构件支承的板为双向剪切板单元模型；（２）作为简化方法，在建筑结构单元的纵向和横向分别按抗侧力构件支承的板，作为剪切梁单元模型考虑水平地震作用；（３）对于刚度和质量分布均匀的结构，可按横向和纵向柱列平面分别计算水平地震作用

Spatial Entirety Analysis of The Structures Under Earthquake

In this paper, the authors proposed the spatial entire model of building structures under horizontal earthquake actions, and discused the calculating method for this model. According to the model, we studied the building in the power station where we had made the test. The computing results coincide with the testing results. Comparing the calculated results, the following conclusions are obtained: (1) If the stiffness and mass of the structure are not uniformly distributed, the slab supported by the lateral force resisting members may be taken as two-directional shear plate.(2) As a simplified method, the foremost slabs may be taken as shear-beam model, and consider the earthquake actions along the longitudinal and transverse directions of the structural unit. (3) When the stiffness and mass of the structure are uniformly distributed, the horizontal seismic force can be calculated along the longitubinal and transverse direction in column plan of the structure respectively.
