| 摘 要： | 带加强层高层、超高层建筑结构目益增多,针对此类结构提出合理的抗震设计方法十分必要.根据模态理论考虑高阶振型对结构反应的贡献,基于较成熟的多层结构直接基于位移的抗震设计理论,提出了带加强层高层建筑结构直接基于位移的抗震设计方法.方法根据模态理论将结构各个振型分别等效为单自由度体系,计算各单自由度体系的地震响应,进而以振型...

| Abstract: | High rise structures with strengthened stories are widely used nowadays.A rational seismic design procedure for this kind of structure is thus necessary.Higher mode contributions to the seismic response can be considered according to the modal theory.So based on the directly displacement-based seismic design theory,this paper proposes a new directly displacement-based seismic design procedure.In the procedure,each mode of the high-rise structure is equivalent to a single-degree-of freedom system according t... |
