对称结构在水平地震作用下的扭转效应和抗扭设计探讨

Torsional response and seismic design of symmetric structures subject to horizontal earthquakes

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。

The paper studies torsional response of tors that are induced torsional vibration during an placement at the extremes of the structures. Both ied. Results and proposals of for forces induced by seismic the analysed studies torsion. symmetric structures subject to horizontal earthquakes. Some facearthquake are discussed. Seismic torsion is led to increased disstatic analysis and dynamic analysis of the torsion effects are studare presented, which are provided theoretically reasonable design
