扭转位移比
1.
Based upon the analysis on torsion angle effect of vertical members in torsionally irregular structure,it is pointed out that controlling torsional displacement ratio can not totally control the torsional angle of both the floor and the vertical members and disadvantageous effect on the member by torque aroused.
对水平地震作用下扭转不规则建筑竖向构件因层间扭转角引起的扭矩影响进行了分析,指出仅控制结构扭转位移比,并不能涵盖对于楼层及竖向构件产生扭转角,以及由此引起的扭矩不利影响的考虑和控制。
2.
The relation between the torsional angle and period,and the control of the torsional displacement ratio and period ratio are explored.
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。
