［提要］根據(jù)使用要求和鑒定結(jié)果，對(duì)北京工人體育館進(jìn)行抗震加固。通過(guò)多種方案比選，確定了整體加固方案。對(duì)柱采用增大截面方法加固，對(duì)梁、板等采用鍍鋅鋼絲繩網(wǎng)片 聚合物砂漿方法加固。加固后，結(jié)構(gòu)抗震性能得到了改善。分析和試驗(yàn)結(jié)果表明，在屋蓋穩(wěn)定索上直接懸掛吊重，對(duì)原結(jié)構(gòu)影響較小，方案簡(jiǎn)單、滿足安全可靠要求。

Abstract: According to the service requirements and seismic appraiser results, Beijing Worker"s Gym is seismically strengthened. Strengthening method is determined after comparison of different measures. The columns are strengthened with reinforced concrete, beams, slabs are strengthened with wire rope net polymer mortar method. After strengthening, the seismic performance of Beijing Worker s Gym is enhanced. The additional load is directly exerted on the stabilizing cable. Analysis and experiments show that this method is easy and safe.

Keywords: Beijing Worker"s Gym; seismic strengthening; galvanic wire rope ne-polymer mortar; cable supported roof
