摘要

钢筋混凝土框排架结构是我国火电厂主厂房常用的结构形式,结构质量、刚度分布不均匀,结构抗震性能的研究尤为必要。利用动力弹塑性时程分析方法对大型火电厂主厂房框排架结构进行抗震研究。计算结果表明,该方法能反映主厂房结构在地震荷载作用下其响应随时间变化的全过程;主厂房横向框排架和纵向框架存在较多的薄弱环节,分析结果可为设计提供重要依据。
Frame-bent structure is the structural form that is frequently used in the main mill building of a thermal power plant,whose structural quality and rigidity are distributed non-uniformly.It is necessary to research earthquake resistant behavior of this structure.In order to achieve the performance of main building under rare earthquake,a time history response analysis is carried out.The result shows that the complete dynamic response process of the structure under seismic loads varying with time is showed with time history method.The frame-bent structure has many weak links,which merits attention during design of such structure.
