Abstract
There are benefits of weight optimized structures in many engineering fields. In civil
engineering it can for instance be associated with cheaper structural parts and easier
transportation. In this study a genetic optimization algorithm for weight minimization of steel
trusses has been developed in MATLAB. Constraints regarding material strength and
buckling stability are taken from “Eurocode 3: Design of steel structures” and implemented in
the algorithm.
Genetic programming is an effective search technique based on natural selection. The
basic idea is to combine good solutions to a certain problem over many generations to
gradually improve the result. All solutions are initially created randomly, and they are
individually... (More)

individually represented by a binary string with some similarities to natural chromosomes,
hence the name genetic programming. (Less)
