摘　　要：以上海某1995年建成的超限高层办公楼特殊类装修项目为研究对象,探讨了既有建筑在未经超限分析情况下的加固改造设计。阐述了加固设计中的关键要点,包括结构抗震措施、计算分析及主要加固措施。通过多种软件进行结构模型计算和分析,确保了结构在设防烈度及罕遇地震时的安全性。加固措施包括剪力墙、柱和梁的加固方法,优先采用轻量化加固方法以减小对原结构的影响。项目成功保证了结构安全,最大程度保留了原始结构,展现了良好的经济适用性,为类似超限高层建筑的加固设计提供了实例参考。Focusing on the special decoration project of an over-limit high-rise office building built in 1995 in Shanghai,the reinforcement and renovation design of an existing building without prior over-limit analysis is explored.The key aspects of the reinforcement design are detailed,including seismic measures,computational analysis,and primary reinforcement strategies.Structural modeling and analysis are conducted using various software tools to ensure the safety of the structure under both design intensity and rare seismic events.Reinforcement techniques include strengthening of shear walls,columns,and beams,with a preference for lightweight reinforcement methods to minimize the impact on the original structure.The project successfully guarantees structural safety,preserves the original structure to the greatest extent,and demonstrates excellent economic feasibility,offering a reference for similar over-limit high-rise building retrofits.
