超高层建筑结构时变作用耦合效应分析方法

Coupling effect analysis of time-varying action for super tall building structures

传统的超高层建筑时变分析分析方法是通过结构弹性时变分析得出结构的内力时程进而得出构件的非弹性变形时程,而并未考虑内力时程与变形时程之间的相互关联性。事实上,这种由于内力时程与变形时程之间的相互耦合作用而产生的结构内力以及变形差异在设计过程中是不可忽略的。本文基于超高层建筑结构的非弹性时变作用分析方法,分别对竖向构件的变形以及结构的强度设计进行计算,得出考虑耦合作用的时变分析方法在设计过程中与传统的结构设计方法的差异。

The forces of super tall building structures is obtained by the structural elastic time-varying analysis method in the traditional time-varying analysis, thus derived inelastic deformation of time-histories of components, without considering the coupling effect between internal forces and deformation of time-histories. In fact,the structural internal forces and different deformation produced by the mutual coupling effect between internal forces and deformation of timehistories can't be ignored in the design process. The deformation of the vertical members and the design of structure strength have been calculated based on the inelastic time-varying analysis method of the super high-rise structures in this paper to obtain the differences between the time-varying analysis methods considering the coupling effect and the traditional structural design methods.
