Risk Acceptance Criteria for Performance-Oriented Design Codesby Stuart G. Reid, Univ of Sydney, Sydney, Australia,
Abstract: A general basis for the determination of 'acceptable risks' needs to be established to facilitate the development of risk-based performance-oriented design Codes. To determine acceptable risks, it has been proposed that the methods of probabilistic risk assessment should be used. The paper briefly reviews the methods of probabilistic risk assessment, with regard to applications for the purposes of building regulation. It is concluded that design decisions should not be based on single-valued measures of risk such as those contrived according to the methods of probabilistic risk assessment. A general basis for the development of risk-based design criteria is outlined.
