[摘要]郑州科技馆属于特别不规则抗震超限高层建筑,其结构布置存在平面凹凸不规则、扭转不规则、楼板开洞、夹层、斜柱等不规则项。为满足抗震设计要求,采取了基于性能的抗震设计方法,并采用SAUSAGE软件进行罕遇地震下的动力弹塑性分析,以研究整体结构在大震下的动力响应。本工程采用了连梁阻尼器增加了结构的耗能能力,提升了结构的整体抗震性能。

Abstract:Zhengzhou Science and Technology Museum belongs to seismic overruns tall building, for its structural arrangement with plan concave-convex irregularity, torsional irregularity, openings in the floor, mezzanine floors and inclined columns. In order to satisfy the requirements of the structural seismic design, the performance-based seismic design method was selected.The dynamic elasto-plastic analysis was carried out using SAUSAGE software to study the response of the structure under rare earthquake. The application of the coupling beam damper in the project increases the energy dissipation capacity and improves the anti-seismic performance of the structure.

Keywords:Zhengzhou Science and Technology Museum; beyond code limit; performance-based design; dynamic elasto-plastic analysis; coupling beam damper
