摘要
通过单层偏心结构运动方程的解析过程,确立了影响结构弹性反应的主要结构参数,并采用Matlab模拟各参数对结构地震作用效应的影响规律。分析了强度偏心距对偏心结构非弹性地震反应的影响规律,提出在实际结构设计中可以通过提高柔性边抗侧力构件的屈服强度来降低非弹性扭转破坏的影响,为偏心结构的抗震设计提供了有价值的参考依据。
According to the analysis of the dynamic equation, the main parameters influencing the structure's elastic response are established, and the earthquake action's effects laws influenced by those parameters is presented. The main parameter influencing the eccentric buildings' inelastic response is strength eccentricity. During the seismic design, the inelastic twist destroy can be reduced according to strengthen the flexibility side elements. [
