【摘要】 针对异形柱框架结构的主要特征,在总结异形柱框架结构主要抗震性能试验成果的基础上,提出异形柱框架结构的概念设计.结合工程应用实际,通过对结构布置、柱肢长宽比、填充墙竖向刚度控制、柱梁刚度比和配筋形式及间距等方面的的分析,明确初步设计中概念设计的原则和要求.通过算例,对影响异形柱框架结构抗震性能的主要参数进行分析,并采用动力时程分析方法,分别考察在设防和罕遇地震水准下结构的整体抗震性能.结果表明,在7度(0.15 g)下的异形柱结构的概念设计,符合抗震要求.更多还原

【Abstract】 Based on summarizing the experimental results of seismic performance of frames with special-shaped columns,the requirements of conceptual design are clarified,which include structure layout,length-width ratio of columns limb,vertical rigidity of infilled wall,columns-beam rigidity ratio and reinforcement.The numerical example is presented,the main parameters influencing the seismic performance of special-shaped column frames are analyzed.The seismic performances of the structure under both frequent and rare earthquakes are discussed by the time-history dynamics analysis.The result indicates that the conceptual design of frame with special-shaped columns meets the seismic requirements of 0.15 g earthquake action.更多还原
