Abstract:

Through the United States the structural safety of major and/or innovative structures has become a serious concern for engineers and to the general public. The objective of this paper is to present an integrated risk assessment methodology for structural safety. The practical applicability and versatility of this integrated methodology has been illustrated based on a priori probabilities for specific events. The risk assessment process includes two major components: 1) risk estimation, and 2) risk acceptability analysis. For the risk estimation, a quantitative analysis procedure incorporating the event tree and fault tree has been developed. For the risk acceptability analysis, a revealed preference model based on the anatomy of risks for a reinforced concrete structure has been formulated.
