目前对平面不规则结构扭转振动效应研究集中于弹性阶段，对结构非弹性受力阶段的扭转效应控制缺乏明确的评价方法和指标。提出通过考察θr／u在弹塑性阶段的变化来对结构扭转振动响应进行评价，并以此为基础定义了结构弹塑性扭转振动效应的敛散性。采用PERFORM-3 D对三种典型的结构平面布置进行弹塑性扭转振动效应敛散性计算，对计算结果进行对比分析，验证了敛散性分析对结构弹塑性扭转振动效应评价的有效性和必要性，并进一步对结构弹塑性扭转振动效应敛散性的主要影响因素进行简要分析。最后，探讨了敛散性指标作为结构的弹塑性扭转振动效应评价指标的合理性和优越性。

Current studies of the torsional vibration effect in symmetric buildings focus on the elastic stage and there is no clear evaluation methods or index for inelastic torsional effect control .This paper proposed a method to evaluate torsional vibration effect by investigating variation of θr/u.A convergence index of elasto-plastic torsional effect in asymmetric buildings was also defined .Torsional vibration effect convergence calcula-tion was finished for three typical buildings by using PERFORM-3 D.Calculation results were analyzed to veri-fy the necessity and effectiveness of convergence index .A brief analysis on main factors of convergence index was carried out .Finally, the rationality and superiority of convergence index as a structural elasto-plastic tor-sional vibration effect evaluation index were discussed .
