| 摘 要： | 结合工程实例，指出了大底盘不对称双塔结构的振动属于空间的扭转耦联振动，各阶振型对基底剪力的贡献并不是随振型序递增而单调递减的，应该选取足够的振型数计算地震作用效应。 |
| 关 键 词： | 非对称双塔 大底盘 平移-扭转耦联 动力特征 |

| Abstract: | The calculation result of the example structure is presented.It shows that the vibration of non-mirrored two-towers high building with enlarged base is translational-torsional coupled vibration.The devotion of every vibration mode to the total shear-force at the bottom of the building is not reduced with the increasing of vibration mode number.The vibration mode number should be chosen adequately. |
| Keywords: | non-mirrored two-towers enlarged base translational-torsional coupled vibration dynamic property |
