摘　　要：通过对结构在水平力作用下扭转效应的几何关系及受力机理的分析,比较了分别采用扭转位移比及层扭转角作为判别指标的不同计算结果及合理性,提出了采用层扭转角作为结构扭转控制辅助判别指标的建议,同时给出了不同结构类型层扭转角正切的建议限值,可作为相关结构设计的参考。Based on the structure under the action of horizontal force torsion effect of the geometric and stress mechanism analysis,it compared the torsional displacement ratio and twist angle used respectively as the discriminant index,the different calculation results and rationality of proposed using torsion angle as discriminant index structure torsion control proposal.At the same time puts forward some suggestions of different structure types of reverse tangent limit,which can be used as reference for structure design.
