Garbatov, Y. e Georgiev, P. (2017), “Optimal design of stiffened plate subjected to combined stochastic loads”, Progress in the Analysis and Design of Marine Structures, Guedes Soares, C. & Garbatov Y. (Eds.), Taylor & Francis Group, London, UK, pp. 243-252
The objective of this work is to perform a multi objective nonlinear structural optimization of a stiffened plate subjected to combined stochastic compressive loads accounting for the ultimate strength and reliability based constraints in the design. The solution of a dual objective structural response, in minimizing the weight and structural displacement, is considered as a multi-objective optimization problem. The Pareto frontier solution is used to define the feasible surface of the design variables. The reliability index, which defines the shortest distance from the origin to the limit-state boundary, is employed to identify the topology of the stiffened plate as a part of the Pareto frontier solution in reducing the failure probability for the critical limit states by satisfying the target reliability level and identifying the existence of risk driven by the design solution.
