摘要
未考虑抗震设防或抗震设防标准较低的既有体育馆安全性往往不满足现行规范抗震设防要求,因此需进行抗震鉴定及抗震加固。以20世纪70年代建造的大型体育馆为依托,对装配式场馆进行检测和抗震性能分析,根据检测及分析结果提出具体加固方案,从而在整体上提高体育馆抗震性能。
The safety of existing gymnasiums without considering seismic fortification or with low seismic fortification standards often fails to meet the requirements of current codes for seismic fortification,so seismic appraisal and seismic reinforcement are needed.Based on the large gymnasium built in the1970 s,the inspection and seismic performance appraisal of the prefabricated gymnasium are carried out.According to the results of the inspection and analysis,the concrete reinforcement scheme is put forward,so as to improve the seismic performance of the gymnasium as a whole.
