超限高层建筑结构设计研究

Structural Design of Over-limit High-rise Buildings

本文针对超限高层建筑的超限情况,对结构进行小震作用下振型分解反应谱分析和弹性时程分析;大震作用下弹塑性时程分析;对关键构件在中震和大震作用下进行抗震性能化设计。根据分析结果对结构提出相应加强措施,使结构具备良好的抗震性能,为超限高层建筑结构设计相关工程项目提供参考。

In this paper,the vibration mode decomposition response spectrum analysis and elastic time-history analysis under the action of small earthquakes are carried out for the over-limit situation of high-rise buildings.Elastic-plastic time history analysis under large earthquakes and the seismic performance design of key components under medium and large earthquakes are carried out.According to the analysis results,the corresponding strengthening measures are put forward to make the structure have good seismic performance and provide reference for the related structural design of over-limit high-rise buildings.
