摘　　要：地震会产生次生灾害,为解决灾后避难问题,本文拟对既有大空间结构进行加固,根据PKPM软件计算出增大截面法和增设钢支撑法对大空间建筑抗震加固的效果并进行分析。通过工程实例计算及分析,表明增大截面法无法显著提高原结构的抗震性能,且不符合绿色环保的设计理念,而增设钢支撑法可明显提高结构的抗侧移能力,故采用钢支撑加固法对实例体育馆进行加固改造更为科学可行。Earthquake will produce secondary disasters,to solve the problem of post-disaster refuge,the large space structure is reinforced,the effect of enlarged cross section method and adding steel support method on large space building aseismic reinforcement is calculated with PKPM software and analyzed. Through comparative analysis and calculation of engineering examples,the results show that increasing the cross section method can＇ t significantly increase the seismic performance of the original structure,and do not conform to the green environmental protection design concept,while adding steel support method can significantly improve the lateral resistance of the structure. So the steel support reinforcement method adopted to the gym is more scientific and feasible for reinforcement and reconstruction.
