Abstract
Development of reliability and risk methods for structural components and structures is a major activity at Lewis Research Center. It consists of six program elements: (1) probabilistic loads, (2) probabilistic finite element analysis, (3) probabilistic material behavior, (4) assessment of reliability and risk, (5) probabilistic structural performance evaluation, and (6) extension to other applications. Recent progress includes: (1) the evaluation of the various uncertainties in terms of cumulative distribution functions for various structural response variables based on known or assumed uncertainties in primitive structural variables, (2) evaluation of the failure probability, (3) reliability and risk-cost assessment, and (4) an outline of an emerging approach for eventual certification of man-rated structures by computational methods. Collectively, the results demonstrate that the structural durability/reliability of man-rated structural components and structures can be effectively evaluated by using formal probabilistic methods.
