【摘要】 介绍了中国银行大楼复杂的结构体系和健康状况,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。对部分重要的或有代表性的关键构件(梁、板、柱等)进行了补强加固的试验验证,用纯钢框架模型对加固后的构件进行计算,将计算结果与实测值进行了分析比较,表明该大楼工程加固效果达到设计要求,加固后大楼整体安全可靠性满足使用要求。更多还原

【Abstract】 Complicated structure and healthy state of China Bank, Hankou Building, and " integer contact steel frame system" structure strengthening plan and " tri-connection" structure strengthening method are introduced. Using experiment, some important member and representational crux member are validated. Reinforced structure are calculated as pure steel frame model, and the calculated result are compared with experimental result. The appraisal shows that the effect of strengthening achieves the request of design, and the building is safe in use now.更多还原
