（廣州瀚華建筑設計有限公司，廣州 510655）[摘要] 通過對結構在水平力作用下扭轉效應的幾何關系及受力機理的分析，比較了分別采用扭轉位移比及層扭轉角作為判別指標的不同計算結果及合理性，提出了采用層扭轉角作為結構扭轉控制輔助判別指標的建議，同時給出了不同結構類型層扭轉角正切的建議限值，可作為相關結構設計的參考。[關鍵詞] 結構扭轉; 扭轉位移比; 扭轉角中圖分類號：TU318.1 文獻標識碼：A 文章編號：1002-848X(2013)S2-0423-03作者簡介：鄭建東，教授級高級工程師，一級注冊結構工程師，注冊土木工程師（巖土）,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
