Maximum Load and Minimum Volume Structural Optimization
A bi-criteria optimization is considered whose objectives are the maximization of the load sustained by a structure and the minimization of the structure's volume. As the objectives are conflicting, the solution to the problem is of the Pareto type. The problem is elaborated for a thin-walled column of cruciform cross-section, prone to flexural and torsional buckling. A numerical example is als...
متن کاملEvolutionary Algorithm For Structural Optimization
This poster paper summarizes ongoing dissertation research (under the direction of Dr. Christopher M. Foley) concerned with the utilization of genetic algorithms for the optimization of steel structures that have semi-rigid connections using advanced inelastic analysis and performance based engineering design. An evolutionary algorithm has been developed that extends the standard genetic algori...
متن کاملRank-Based Evolutionary Algorithm For Structural Optimization
An evolutionary algorithm that utilizes a-priori problem specific information and allows intuitive representation of the problem design variables is proposed. A technique for conditioning the components of the fitness statement using ranking and a graphical method for monitoring components of the rank based fitness function are presented. By utilizing generationally dependant non-linear rank ba...
متن کاملMulti-objective Optimization of web profile of railway wheel using Bi-directional Evolutionary Structural Optimization
In this paper, multi-objective optimization of railway wheel web profile using bidirectional evolutionary structural optimization (BESO) algorithm is investigated. Using a finite element software, static analysis of the wheel based on a standard load case, and its modal analysis for finding the fundamental natural frequency is performed. The von Mises stress and critical frequency as the proble...
متن کاملFirst order rejection tests for multiple-objective optimization
Three rejection tests for multi-objective optimization problems based on first order optimality conditions are proposed. These tests can certify that a box does not contain any local minimizer, and thus it can be excluded from the search process. They generalize previously proposed rejection tests in several regards: Their scope include inequality and equality constrained smooth or nonsmooth mu...
