摘　　要：本文建立对桥梁中钢与钢筋混凝土结合梁可靠度分析的半随机过程模型，研究了考虑车辆荷载（包括活载和冲击荷载）与恒载组合作用于下结合梁的可靠度评估。ＴＲ荷载组合规则被用来考虑荷载效应之间的关系。运用系统可靠度评估的方法，结合梁被模型化为由混凝土板、剪力传递器和钢梁串联而成的结构系统。工程设计的数值算例表明，本文提出的可靠度分析模型可用于进行结合梁目标可靠度设计。A semi stochastic process model is developed for reliability analysis of steel concrete beam in bridge engineering. Reliability evaluation was made on composite beam structure under combined action of dead load and traffic load. The TR combination rule was used to consider the relation between load effects. The composite beam structure is modeled as a series system consisted of concrete slab, shear studs and steel beam. The numerical example from design practice puts the achieved reliability model into use of object reliability design.
