General purpose procedure for reliability based structural optimization under parametric uncertainties
The objective of this paper is to integrate the general purpose structural reliability analysis program, NESSUS (Numerical Evaluation of Stochastic Structures Under Stress), with mathematical optimization capabilities for achieving optimal designs. The field of reliability analysis has matured in the last few years to the level where probabilistic analysis is conducted for a multitude of finite elements by considering the uncertain information on geometry, material properties, loads and boundary conditions. For conducting structural reliability analysis, several disciplines are incorporated in NESSUS to consider different failure modes. This research developed RELOPT (RELiability based structural OPTimization), an automated procedure for design optimization by integrating reliability analysis, sensitivity analysis, function approximations and data base management. Example problems are presented on beam and plate structures with strength and eigenvalue requirements and structural mass minimisation.
