| 摘 要： | 针对水平地震作用下对称结构抗扭设计中存在的问题,分析了对称结构扭转振动的原因,然后分别采用静力和动力方法研究了考虑偶然偏心作用时结构反应的增大效应,比较了这两种方法计算结果的异同,最后结合我国抗震规范提出了适当的结论和改进建议,为对称结构的抗扭设计提供了理论依据。

| Abstract: | The paper studies torsional response of symmetric structures subject to horizontal earthquakes.Some factors that are induced torsional vibration during an earthquake are discussed.Seismic torsion is led to increased displacement at the extremes of the structures.Both static analysis and dynamic analysis of the torsion effects are studied.Results and proposals of the analysed studies are presented,which are provided theoretically reasonable design for forces induced by seismic torsion. |

| Keywords: | symmetric structures torsional response to earthquake accidental eccentricity design resistant to torsion |
