On the safety prediction of deteriorating structures

Abstract

Engineering modeling of safety prediction of the structures subjected to aggressive environmental actions and rectangular renewal pulse processes of single and co-incident extreme loads is considered. The safety margins of deteriorating particular members are modeled as a random decreasing sequences. The prediction of long-term survival probabilities of structures is based on the unsophisticated method of transformed conditional probabilities. The prob-ability-based design of deteriorating members is illustrated by the numerical example.
