| 摘 要： | 某工程位于昆明市,主体结构高153.1m,为型钢混凝土框架-剪力墙核心筒体系。建筑总高度超过了《高层建筑混凝土结构技术规程》中规定的B级高度,为提高结构的抗震性能,该工程采用消能减震技术控制结构的地震反应,对消能减震结构进行了设计,确定了消能器附加给结构的阻尼比值。为给结构设计提供可靠的参考依据,采用PERFORM-3D软件,对设有非线性粘滞阻尼器的该结构进行罕遇地震作用下动力弹塑性时程分析,评估该结构的整体性能及其构件的屈服情况,结果表明该消能减震结构基本能达到预期抗震性能目标。

| Abstract: | This project is located in Kunming City, the height of main structure is 153.1 m and it uses steel-reinforced concrete （SRC） frame-core wall structure. The total height of structure is beyond that of B level specified in Technical Specification for Concrete Structures of Tall Build- ing. Seismic energy dissipation technology was adopted to improve the seismic performance. Be- sides, structure of energy dissipation was designed, and the additional damping ratio of damper was determined. Dynamic elastoplastic analysis of the structure with nonlinear viscous damper and undergoing rare earthquake was conducted by software PERFORM-3D. Results show that the structure can achieve predetermined earthquake resistance performance target. |
