| 摘 要： | 对于不规则多高层建筑结构在地震作用下的反应,本文从两个方面进行分析,一是分析结构竖向质量的变化对设计中所采用的基底剪力及结构自振周期的影响,二是对于较复杂的局部层偏心结构(平面不规则)发生的质量中心与刚度中心偏离进而产生平移-扭转耦合作用进行分析。

| 关 键 词： | 结构竖向不规则性 结构平面不规则性 偏心结构 平移-扭转耦合震动 |

| Abstract: | For the response of irregular multi-storey structures under earthquake action,this paper analyze it from two respects.One is to analyze the variations of the base shear of the structure and the period of vibration due to the change of the vertical mass of the structure.The other is to analyze the effect of couple lateral-torsional vibration of eccentric structure(aclinic irregularity of the structure)due to separation of the center of mass and the center of stiffness. |

| Keywords: | Vertical irregularity of the structure Aclinic irregularity of the structure Eccentric structure Couple lateral-torsional vibration |
