Risk, Fragility and Reliability Analyses in Structural Engineering

摘要

It has been for a long time that the structural systems’ load andstrength were considered in a deterministic manner by engineers anddesign codes. In this case, a safety factor was defned based on the ratiobetween the strength and the applied load on structure, which usuallyreferred as the measure of the reliability of the considered structure.However, in the recent years, the researchers found that because of theuncertainties available in the strength, loadings and modeling of thestructural system, the traditional deterministic approach cannot beconsidered accurate anymore. Hence, the probabilistic techniques havedeveloped and are being used to evaluate the life-cycle performanceand reliability of structures [1,2]
