【提要】 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。提出了相应的竖向构件考虑扭转角影响在内的抗震验算方法，作为对新抗震规范和新高规扭转不规则建筑抗扭设计方法的一点补充建议。

Aseimic Analysis on Torsion Angle Effect of Vertical Members in Torsionally Irregular Structure
/Wei Lian,Wang Sen(Shanghai Wei Lian Structure Design Institute Shenzhen Office, Shenzhen 518034，China)
Abstract:Based upon the analysis on torsion angle effect of vertical members in torsional
ly 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.It also provides methods on designing vertical members resisting torque as a supplementary suggestion to the torsion design methods described in the codes.
