摘要
以结构的总费用最小为目标 ,建立考虑动态风险成本的工程结构系统可靠性优化模型 ,分析给出风险成本与结构可靠性之间的定量关系 ,提出考虑动态风险成本的工程结构系统可靠性分配方法。算例结果表明 。
The optimal model of engineering systems reliability with the consideration of dynamic risk cost was presented with the object of minimum cost. The relationship between risk cost and structural reliability is derived. The optimal allocation method of engineering systems with the consideration of dynamic risk cost is proposed. The obtained results are illustrated by a numerical example, moreover, the results indicate that the total cost of engineering systems considering dynamic risk cost is more economical than that of engineering systems only considering original cost.
