| 摘 要： | 大底盘非对称结构的受力情况比对称结构更为复杂,文章分析了在水平地震作用下大底盘非对称多塔楼结构协同计算与各单塔独立计算时的地震反应,并指出多塔楼协同计算时,应选取足够数量的振型数才能使高阶振型中对地震反应起一定作用的振型考虑进去,以满足结构设计精度的要求。

| Abstract: | The horizontal eathquke response of non-symmetrical structure with multi-towers is more complex than the symmetrical one.In order tho prove this,the multi-towers structure and the separate tower which is separated from the multi-towers are culculated and analysed respectively,showing that enough number of vibration mode is needed to make sure that high vibration mode which is important to the horizontal seismic response is considered in the calculation. |

| Keywords: | mutil-towers structure non-symmetrical structure seismic response vibration mode number |
