摘　　要：杭州体育馆建于20世纪60年代末,是我国较早建成的马鞍形悬索屋面体育建筑,至今已超过一般建筑50年的设计使用年限,作为历史保护建筑,其将继续使用,并将作为2022年杭州亚运会拳击比赛主场馆。根据后续使用年限30年的A类建筑结构安全性和抗震性能鉴定结果及提升改造后的建筑功能要求,分析了上部承重结构体系不合理之处及需要加固的结构构件。采用综合抗震能力验算的方法,分别从地基基础、结构体系、结构构件、梁柱节点、屋面索网结构等方面对本工程进行了结构加固改造设计。同时,鉴于原建筑按非抗震设计,本工程采用性能化设计的思路,通过利用结构构件抗震承载力冗余度,放宽部分构造要求从而缩小加固范围、节约成本、缩短工期,同时最大限度减轻结构加固对原有建筑的影响,实现对历史建筑的保护。Built in the late 1960 s,Hangzhou Gymnasium is a saddle-shaped suspended roof sports building built earlier in China.It has exceeded the design service life of general buildings for 50 years,as a protective historical building,it will continue to be used for Asian Games Hangzhou 2022 boxing competition.According to the appraisal results of the safety and seismic performance of the class A building with a subsequent service life of 30 years and the functional requirements of the upgraded building,the unreasonable load-bearing structure system of the superstructure and the structural components that need to be reinforced were analyzed.By adopting the method of comprehensive seismic capacity checking,the structural reinforcement and reconstruction design of this project was carried out from the aspects of foundation,structural system,structural components,beam-column joints,roof cable-net structure and so on.At the same time,in view of the non-seismic design of the original building,this project adopted the idea of performance-based design.By using the redundancy of seismic bearing capacity of structural components,some structural requirements was relaxed.Thus,the scope of reinforcement was reduced,the cost was saved and the construction period was shortened.The influence of structural reinforcement on the original building was minimized,and the protection of historical buildings was achieved.
