摘要(Abstract):

杭州滨江宝龙酒店为双核心筒上支撑大跨钢桁架连体结构体系,结构超限。为了保证结构的安全性,采用YJK和SAP2000对结构进行了抗震性能设计。针对各主要受力构件的抗震性能目标,采用YJK和SAP2000对结构进行了小震弹性反应谱分析、小震弹性时程分析、中震构件性能分析、大震弹塑性时程分析以及楼板舒适度分析。计算结果表明,对部分构件采取一定的构造措施加强后,结构能实现预定的性能设计目标,同时也能提高结构的安全性。
Connective structure with steel truss is adopted for Powerlong Plaza in Binjiang of Hangzhou.The structure performance index is beyond the limits of codes.In order to meet the functional requirements of the building,performance-based seismic design was carried out using YJK and SAP2000.According to the performance-based seismic design objectives of the structure,various programs were used to conduct the elastic response spectrum analysis and elastic time-history analysis under frequent earthquake,structure member performance analysis under moderate earthquake,elastic-plastic time-history analysis under rare earthquake and floor stress analysis.The analysis results illustrated that the structure can meet with seismic performance requirements,improve the safety and reliability of the structure by the strengthening measurement.
