Reliability-Based Optimization of Structural Systems involving Discrete Design Variables

Reliability-Based Design Optimization of Trusses with Linked-Discrete Design Variables using the Improved Firefly Algorithm

In this paper, an approach for conducting a Reliability-Based Design Optimization (RBDO) of truss structures with linked-discrete design variables is proposed. The sections of the truss members are selected from the AISC standard tables and thus the design variables that represent the properties of each section are linked. Latin hypercube sampling is used in the evaluation of the structural rel...

Optimum Structural Design with Discrete Variables Using League Championship Algorithm

In this paper a league championship algorithm (LCA) is developed for structural optimization where the optimization variables are of discrete type and the set of the values possibly obtained by each variable is also given. LCA is a relatively new metaheuristic algorithm inspired from sport championship process. In LCA, each individual can choose to approach to or retreat from other individuals ...

Methods for reliability based design optimization of structural components

Cost and quality are key properties of a product, possibly even the two most important. One definition of quality is fitness for purpose. Load-bearing products, i.e. structural components, loose their fitness for purpose if they fail. Thus, the ability to withstand failure is a fundamental measure of quality for structural components. Reliability based design optimization (RBDO) is an approach ...
