（广州瀚华建筑设计有限公司，广州 510655）[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。[关键词] 结构扭转; 扭转位移比; 扭转角中图分类号：TU318.1 文献标识码：A 文章编号：1002-848X(2013)S2-0423-03作者简介：郑建东，教授级高级工程师，一级注册结构工程师，注册土木工程师（岩土）,Email:zhengjiandong@gzhanhua.com。Using torsion angle as the structure torsion control indexZheng Jiandong, She Jun（Guangzhou Hanhua Architects&Engineers Ltd., Guangzhou 510655, China）Abstract： 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.Keywords：structure torsion; torsion displacement ratio; torsion angle
