【摘要】 基于西昌市某多层框架结构加固工程,采用增大截面法加固框架柱。对比分析加固前后,该工程局部单柱各项内力参数和各楼层综合抗震能力指数,证明增大截面法对框架柱软弱有明显加固作用,以便类似工程借鉴,服务于工程建设。更多还原

【Abstract】 Based on the reinforcement engineering of a multilayer frame structure in Xichang,the increase section method is used to reinforce the frame column.By comparative analysis of the internal force parameters for local column and the comprehensive seismic capacity index for every floor before and after the reinforcement,it demonstrates that increased frame column section has obvious effect for the reinforcement,which will be covered in the similar projects,and serve the engineering construction.更多还原
