摘　　要：采用YJK和ETABS对广州白云国际会议中心国际会堂结构进行弹性分析,采用Perform-3D进行罕遇地震作用下的整体结构弹塑性动力分析,并通过采取针对性的加强措施,改善了结构受力,提高了结构抗震性能,达到了预设的抗震性能目标。对大跨度钢结构构件进行方案选型,提出了大跨度钢结构桁架局部构件后装施工控制法和大悬挑钢结构桁架构件局部弯矩释放法,可以有效地减小结构构件局部受力,更加经济合理。对主会场大跨度楼盖进行竖向舒适度分析,结果表明竖向振动加速度满足规范要求,人群激励模式起控制性作用。通过采用合理的结构方案,以及与建筑专业的密切配合,很好地实现了建筑功能及建筑造型,以及项目快速建造的要求。The elastic analysis of the international hall structure of Guangzhou Baiyun International Conference Center was carried out by YJK and ETABS.The elastic-plastic dynamic analysis of the whole structure under rare earthquake was carried out by Perform-3D.By taking targeted strengthening measures,the stress of the structure was improved,the seismic performance of the structure was improved,and the preset seismic performance target was achieved.The scheme selection of large-span steel structure members was carried out,and local members after installation construction control method of large-span steel structure truss and the local moment release method for member of large cantilever steel structure truss members were proposed,which can effectively reduce the local stress of structural members and is more economical and reasonable.The vertical comfort analysis of the large-span floor of the main venue was carried out.The results show that the vertical vibration acceleration meets the requirements of the code,and the crowd excitation mode plays a controlling role.Through the use of reasonable structural schemes and close cooperation with the architectural profession,the requirements of architectural functions and architectural modeling,as well as the rapid construction of the project,are well realized.
