| 摘 要： | 钢筋混凝土异形柱由于截面几何性质的特殊性,在进行该类结构的抗震计算时,地震作用方向是一个不可忽视的因素,通过对异形柱截面和异形柱结构的计算结果分析,说明了无论是在异形柱框架结构中,还是一般结构中部分采用了异形柱,都应根据具体情况考虑地震作用方向的不利影响。

| Abstract: | Due to the particularity of geometric property of special-shaped cross-section,the horizontal directions of earthquake action could not be neglected for the design of structures with such type of columns.According to the numerical result of cross-section calculation and global analysis of the structures with special-shaped columns in this paper,adverse effect of the earthquake action direction on seismic responses of the structures should be taken into account. |

| Keywords: | special-shaped column global analysis horizontal seismic direction ratio of section height to section thickness sensitivity |
