摘要
本文对结构系统可靠性分析问题进行了深入的研究 ,在全局分枝 约界算法的基础上 ,建立了结构系统失效模式识别和可靠性分析的统一理论 。
In last two decades,collapsing and overturning events are unceasingly occurred in some large?scale structures in the world wide These structures may be large?scale bridges,tall buildings or offshore?drilling platforms It is attracted the attention from the world There two methods are used for estimating the reliability of large?scale structures A unified theory of the failure mode identification and reliability for structural system is proposed in the paper It is based on the global branch?and?bound algorithm Some discussions are made on the provableness of structural reliability estimation in the field of civil engineering
