STRUCTURAL OPTIMIZATION MODEL WITH IMPRECISE RESOURCES

The main goal of the structural optimization is to minimize the weight of structures while satisfying all design requirements imposed by design codes. In this paper, an algorithm is proposed to minimize the weight of nonlinear truss structure under uncertainty. We consider a single objective nonlinear structural design model from Nicholas Ali et al.’s [14] to verify that the proposed algorithm is an effective optimization algorithm in the creation of an optimal design for truss structures. Numerical example is provided to illustrate our algorithm. The result shows that this algorithm is a powerful search and optimization technique for structural design. KEYWORDS: Optimization
