平面不规则高层建筑结构在水平地震作用下的扭转效应与设计

针对平面不规则高层建筑结构在抗扭设计中存在的一些问题,分析了不规则结构扭转振动的原因,分别对平面不规则结构扭转角和周期关系及扭转位移比和周期比的控制问题进行了探讨,结合我国的抗震设计规范和高层建筑混凝土结构技术规程对平面不规则高层建筑结构抗扭设计给出了适当的结论.为平面不规则高层建筑结构抗扭设计提供了参考依据.

Torsional Response and Seismic Design of Irregular Tall Building in Plane Subject to Horizontal Earthquakes

The paper studies the torsional response of irregular tall building in plane subject to horizontal earthquakes.Some factors that induce torsional vibration during an earthquake are discussed.The relation between the torsional angle and period,and the control of the torsional displacement ratio and period ratio are explored.Combining our country's current seismic design,an appropriate conclusion is finally given,which can provide reference to the designs resistant to torsion of irregular tall building in pla...
