摘要: The system reliability evaluation of ductile frame structures presents two difficulties. One is the identification significant failure modes; other computation overall probability contributed from these modes. In this paper, a practical procedure developed, in which mode independent performance function defined using load factor obtained by limit analysis, and response surface approach used to approximate function. With explicit second-degree polynomial, can be readily First Second Order Reliability Method (FORM/SORM). Several examples are investigated, it found that good approximation inner connotative state surfaces structural system. proposed has efficiency enough accuracy for framed structures. difficulty both avoided procedure.
