宿迁市文体综合馆基础隔震设计
Design of base isolated structure of Suqian City Gymnasium
【摘要】 宿迁市文体综合馆位于地震高烈度区,钢筋混凝土空间框架结构、钢网壳屋盖。该工程采用基础隔震技术设计,隔震层由橡胶隔震支座和粘滞消能器组成。对主体结构基础隔震体系的空间模型时程分析结果表明:采用基础隔震措施可显著降低上部结构的地震作用;设置粘滞消能器能较好地解决降低上部结构地震作用和限制隔震层位移之间的矛盾。在该工程中采用基础隔震技术,具有明显的技术经济效益。
【Abstract】 Suqian City Gymnasium is a reinforced concrete spatial frame structure with a steel spatial grid roof located in a region of high earthquake intensity. It occupies 4500 seats and an area of about 13000m2. The isolation layer consists of laminated rubber bearings and viscous dampers. Calculation results of the nonlinear space model time history analysis by SAP2000N software show that the horizontal earthquake action upon the super structure can be greatly reduced by using base isolation technique,as the viscous dampers can effectively restrict the displacement of isolation layer and meanwhile reduce the earthquake action. The base isolation technique used in this project demonstrates obvious technical and economic benefit.
