讨论了不规则桥梁地震反应分析中地震动输入主方向的问题 .根据本文讨论的方法 ,对于不规则桥梁 ,只需沿结构水平面内任意两个不重合的方向输入地震反应谱 ,通过两次反应谱分析 ,便能得到地震沿最不利方向作用时桥梁结构中任意一点或任意一个截面上的最大反应 .
According to the method discussed in this paper, the seismic response spectrum is input to any irregular bridge along any arbitrary two non-coincident directions in the horizontal plane of the structure. Through two reactions Spectral analysis gives the maximum response at any point or in any section of the bridge structure when the earthquake is acting in the most unfavorable direction.
