【摘要】 在分析传统复合箍筋布置方式优缺点的基础上,提出了框架柱箍筋的优化布置方式,即将同一截面上的复合箍筋分散到相邻箍筋截面中间。该布置方式形成连续且间距较小的箍筋布置效果,有利于发挥箍筋对混凝土的约束作用,减小各种因素可能引起框架柱扭转而在柱非加密区产生的裂缝,改善柱中部区域在地震作用下的延性性能,同时可以提高框架柱的施工质量。更多还原

【Abstract】 Based on the advantage and shortcoming of traditional composite stirrup arrangement manner,the optimization arrangement manner of stirrup in frame column is presented that distributing stirrup of the same section to adjacent region between two stirrup sections.This manner can form continuous arrangement effect of hoop bar with less space,and be fit for concrete restricted by stirrup.It also can reduce the concrete crack arised by retortion in the region of frame column,and improve the ductility capability under the earthquake.The construction quality of frame column is improved simultaneously.更多还原
