| 摘 要： | 以8度区某5层框架结构为例,探讨第一周期比及第一、二主振型对扭转效应的影响.通过调整第一周期比和对第一、二主振型提出相应限制,避免引起平面振动与扭转振动的耦合反应,降低结构破坏的几率.采用空间有限元软件SATWE等手段对该框架建立多个实体模型,并进行整体对比分析,提出了该工程较理想的结构抗扭设计方案.

| Abstract: | Taking an example of a five-story frame building in the area of 8-degree earthquake,the influence of 1st period ratio and 1st and 2nd main vibration shapes on tortion effect is discussed.Through adjusting 1st period ratio and controlling 1st and 2nd main vibration shapes,coupling reaction to lead to plain vibration and torsional vibration is avoided and the probality of structural damage is reduced.Using SATWE,a space finite element software,many solid models of the frame strucutre to conduct a whole comparison and analysis so as to bring forth an ideal scheme of anti-torsion design of structures for the project are established. |
