摘要
某5层砖混结构办公楼拟改造为商场,需拆除结构底部墙体以形成大开间。结合结构检测鉴定结果及其受力特点,确定了结构"整体隐形钢框架体系"加固设计方案和"三重连接"加固方法。采用夹墙梁或柱加固原结构后的监测结果表明:该改造工程加固效果达到设计要求,结构整体安全可靠,满足使用要求。
A five-storey brick-concrete office building was planned to be rebuilt into shopping mall , and the wall of the 1st and 2nd floor would be dismantled to form a large space.Based on the test appraisal and the structure forced characteristics, the holistic hidden steel frame structure system strengthening scheme and tri-connection structure strengthening method were used.With the holding-wall beam to the key member of the structure, the monitoring results showed that the result of strengthening achieved the request of the design , and the building was safe in use up to now.
