Multi-Objective Inverse Reliability Design Approach in Geotechnical Engineering
Key Laboratory of Ministry of Education for Geomechanics and Embankment Engineering, Hohai University, Nanjing, China
ABSTRACT
In order to further expand the application of inverse reliability methods in geotechnical engineering, a multi-objective inverse reliability design method is presented in this paper. Based on the HLRF algorithm, the approach can easily realize the traditional single-objective inverse reliability design. Further, multi-objective inverse reliability design is achieved by combining several single-objective inverse reliability analysis modules in a matrix directly without any other mapping functions. The design parameters can be independent of the basic random variables or associated with those random variables, such as their means or standard deviations. Verifications of the proposed algorithm are illustrated through several examples to show the feasibility and accuracy. Based on the proposed approach, the multi-objective inverse reliability design of a strip footing and retaining wall are performed.
Keywords: Geotechnical uncertainty, Inverse reliability analysis, Reliability-based Design, Implicit performance function.
