介绍了我国现阶段结构抗震设计的基本要求,从底部剪力法、振型分解反应谱法、弹性时程分析法等方面,阐述了多遇地震时水平地震作用的计算方法,为建筑结构的抗震设计提供了依据。
The basic requirements for seismic design of structures at the present stage are introduced. From the aspects of bottom shear method, mode decomposition response spectrum method and elastic time history analysis method, the calculation method of horizontal seismic action in case of frequent earthquakes is expounded. Seismic design provides the basis.
