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。
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.
