新疆伊泰甘泉堡会展中心消能减震抗震设计

Energy-Dissipated and Seismic Design of Ganquan pu Convention and Exhibition Center in Xinjiang Uygur Autonomous Region

新疆伊泰甘泉堡会展中心结构体型十分复杂,且结构构件截面受到一定限制。通过框架-普通支撑和框架-屈曲约束支撑两种结构方案的比较,优化结构选型,探讨了框架—屈曲约束支撑框架结构的设计方法及计算要点。经过分析,结构变形满足小震和大震作用下的位移要求,并实现了"大震可修"的设计目标。

Xinjiang Yitai GanQuanPu Convention Center is located in GanQuanPu Development Zone in Ummqi, with seismic intensity of 7 degree, 0.15g, site class III. Because of building functional requirement, the structure is very complicated and the section of structural members is limited. This paper introduces the design method and the key calculation points of the buckling restrained braced （BRB） frame structure and optimises the structure selection through comparing of frame-bracing system and frame-BRB system. After analysis, Structural deformation can not only satisfy the displacement requirements under small earthquake and strong earthquake, but also can reach seismic performance requirement of＂ repairable under Large earthquake＂.
