| 摘 要： | 为加强超限高层建筑结构的抗震性能,最大程度减小地震损失,以某一超限高层建筑为对象,对其结构抗震设计的加强措施和建议进行详细分析。在小震作用下运用pkpm软件MIDAS/Building对建筑结构进行弹性计算对比分析,证明弹性计算的可靠性;借用SATWE对结构在中震或大震作用下不同构件的承载力和截面进行验算;采用midasbuilding软件对该超限高层建筑进行罕遇地震作用下的静力弹塑性分析。根据不同震级下建筑结构线弹性分析结果,对建筑主体结构、结构抗震和地基基础进行加强设计,从中归纳出整体结构的抗震加强措施和建议,说明该超限结构能满足规范的设防要求,是安全可靠的。

| Abstract: | To improve the seismic performance of out-of-code high-rise buildings and minimize earthquake loss, in this work, we propose detailed measures and suggestions for strengthening the seismic design of a certain out-of-code high-rise building structure. Under the action of a small earthquake, we used the pkpm software MIDAS/Building to calculate the elastic properties of the building structure. We used the CAD program SATWE to check the bearing capacity and sections of different members during a moderate or strong earthquake, and midasbuilding software to conduct a static elastoplastic analysis of the high-rise building during rare earthquakes. Based on the results of our linear elastic analyses of the structure during earthquakes of different magnitude, we strengthened the design of the main structure, the seismic structure, and the foundation of the building. We present a summary of the proposed seismic strengthening measures and make suggestions for the whole structure, by which the structure can meet the seismic fortification code requirements and be safe and reliable. |
