大型电厂的输煤栈桥可靠度分析

本文利用多点非一致激励反应普分析理论分析研究了在不同烈度下的输煤栈桥的抗震可靠度。利用响应港分析方法，假定地震过程为平稳随机过程，考虑行波效应及部分相干效应，选择合适的可靠性震害参数，按照结构可靠度分析理论的要求，计算出了结构在不同地震烈度下的失效概率，并给出了震害预测结果及建议。

The Reliability Analysis of The Bridge Used to Carry Coal of the Great Electric Power Plant

In this paper the aseismatic reliability of the long - span strucure with mulifoundatons are analysized and studied by means of the modified response spectrum method which accounts for the mon-uniform seismic excitation. A kind of new seismic reliability computational procedure is suggested base on the non-uniform excitation response spectrum method. The proposed computational procedure is illustrated through analysizing a kind of long - span structures.
