【Abstract】 Applying an approximate method for structural system reliability analysis, the main failure mechanism of structural system is simplified to an equivalent series system. Approximate assignment of structural system is proposed based on the same cost function of main failure mechanism, and the assignment results show that the proposed method can meet the economical and reliable requirements of engineering design.更多还原
