Discrete-continuous design optimization of steel structures using simulated annealing

Abstract

This paper is concerned with the use of the simulated annealing algorithm in optimum design of structures. Specifically, discrete and continuous size optimization of steel trusses is discussed. The objective function is chosen as the weight of the structure and stress, displacement and stability constraints are considered as per Turkish and AISC specifications. Numerical examples are solved using the computer .program SAOPT developed for the purpose. Comparison of results obtained with previously published work reveals the efficiency of the S A approach in both continuous and discrete structural optimization problems.
