摘　　要： 一般复杂高层建筑的质量中心和刚度中心不重合,由此产生结构平扭耦合响应。随着高度的增加,高层建筑结构对风的作用愈加敏感,作用在结构上的风荷载成为控制结构设计的主要荷载。本文对具有刚度偏心的高层建筑结构的风振响应进行研究,通过有限元分析结果发现:风作用于高层建筑结构时,结构刚度中心的偏移对结构响应有明显的影响。 The centers of mass and rigidity of complex high structure can not coincide at all which leads to translation-torsion coupling effects of structure.High building is sensitive to wind effects with building's height increasing,therefore wind effects which act on structure become main control load of structure design.In this paper,wind induced response of high building which having rigidity eccentricity is studied by finite element method.When wind acts on the high building,structure responses are obviously influenced by the offset of rigidity center of the structure by the analysis results.
