摘要
以某平面不规则混凝土框架结构为例,通过建立某综合楼的有限元模型,分析了结构的动力特性,计算了结构的振型有效质量,采用时程分析法对结构输入x、y向水平地震波,得到了结构的顶层位移时程曲线和加速度时程曲线,为结构设计提供了设计依据。
An irregular plane concrete frame structure as an example, through the establishment of a finite element model, the dynamic properties of the structures were analyzed, calculated the structure of the effective mass of the vibration mode. Using time-history analysis method and inputingxandydirection Seismic, the horizontal displacement and acceleration time-history curves of the roof are obtained, the analyses for calculation results could be used to structural design.
