| 摘 要： | 地震时对称结构产生扭转振动的原因是多方面的,其中空间变化地震动作用和结构本身的偶然偏心都可能是引起结构扭转的重要因素.为了能明确实际对称结构会存在偶然偏心现象这一客观事实,从数学概率意义上推导了设计计算时应考虑结构质心偶然偏心影响的必要性,并指出对于多高层结构尤其要考虑偶然偏心的影响. |
| 关 键 词： | 对称结构 偶然偏心 扭转效应 |

| Abstract: | Torsional vibration for symmetrical structure under horizontal seismic has many reasons,spatial variation of ground motions and structure of their own occasional eccentricity are likely to be important factors. In order to show the symmetrical structure will exist accidental eccentricity,the structure accidental eccentricity should be considered in design derived from the mathematical,and noted that the multi-level structure,in particular, to consider the impact of occasional eccentricity. |
