关于斜支撑用于框架结构托梁拔柱加固的探索

Exploration of lateral bracings in supporting beam and removing column reinforcement of frame structure

对比国内目前关于托梁拔柱改造的几种主要加固方式,结合某工程实际改造要求,将柱间斜支撑的设计方法引入既有建筑托梁拔柱改造加固工程中,取得良好实际效果,为托梁拔柱的改造方法的创新作出了有益的尝试,并总结了增加斜支撑加固方法的适用条件,以指导工程实践。

In light of several reinforcement modes of supporting beam and removing column in China recently,combining with actual project reconstruction requirements,it introduces lateral bracings design method into existing supporting beam and removing column reconstruction reinforcement project,and achieves good practical results,which has done great contributions to reconstruction methods of supporting beam and removing column.In the end,it summarizes the applicable conditions of increasing lateral bracings reinforcement method,with a view to guide project practice.
