the rationale of reliability analysis considering damage the rationales involved in the methods adoptive in this article mostly include : reliability theory, finite element theory, monte carlo theory and sensitivity theory etc . the reliability assessment for the structures on active duty developed base on the notions and practical methods of structure reliability design, and at present, the methods which are used more are probabilistic limit design means based on reliability theory 基于損傷下結(jié)構(gòu)可靠性分析的基本原理本文所采用的方法涉及到的基本原理主要包括可靠度理論、有限元理論、montecarlo基本理論、靈敏性理論等。對于現(xiàn)役結(jié)構(gòu)的可靠度評定是以結(jié)構(gòu)可靠度設(shè)計的概念和實用方法為基礎(chǔ)發(fā)展起來的,目前使用較多的是基于可靠度理論的概率極限狀態(tài)設(shè)計法。
