| 摘 要： | 基于层间柱梁强度比方法,设计出一种允许具有部分柱屈服的整体型屈服机制——混合屈服机制钢管混凝土框架结构.该结构通过设立强度较大的边柱来避免层间屈服破坏,而允许中柱柱端屈服,从而放松中柱的强柱弱梁条件.采用弹塑性动力时程分析方法,比较了梁铰屈服机制和混合屈服机制的两种6层框架结构的地震响应,讨论了允许出铰的中柱柱端塑性变形情况,并分析了混合屈服机制实现的可能性.研究表明,层间柱梁强度比是控制钢管混凝土框架结构整体屈服模式的有效参数,不同的强度比下结构表现出极为不同的性能,因此具有重要意义.

| Abstract: | Based on the intensity ratios between columns and beams in a layer,the concrete-filled steel tubular frames of the mixed yield mechanism are designed which permit part of columns to yield.Several edge-strong columns are designed to avoid yield damage in a layer and the column ends in the column are allowed to yield in order to relax strong column weak beam conditions.The seismic responses of 6-storey frame structures which use the beam hinge yield mechanism and the mixed yield mechanism are compared by usin... |
