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.
