摘　　要：利用多点非一致激励反应谱分析理论，分析研究了长跨结构的抗震可靠度。建议了一类基于非一致激励反应谱分析的结构抗震可靠度的计算方法，并通过实例分析，研究了一类长跨结构──输煤栈桥在不同地震烈度下的失效概率。In thispaper the aseismatic reliability of the long-span structure with multifoundations are analyzed and studied by means of the modified response spectrum meth－ od which accounts for the non-uniform seismic excitation. A kind of new seismic reliablity computational procedure is suggested based on the non-uniform excitation response spectrum method. The proposed computational procedure is illustrated through analyzing a kind of long-span structures.
