Discrete minimum weight design of steel structures using EC3 code
The paper presents a practical method of the discrete minimum weight design of steel structures. It is based on a concept of removal of the redundant material by successive diminishing of the size of the least stressed member. It is assumed that the member sizes are available from the European Steel Profiles Catalogues, and the design constraints are given by the rules of the code EC3 for nonsway buildings. Two numerical examples are presented: the classical benchmark problem of a ten-bar truss made of circular hollow sections (24 element catalogue, buckling taken into account) and a portal frame made of HEB sections with broad parallel flanges (11 element catalogue). The proposed method gives, after a reasonable calculation time, a very good approach to the exact optimum solution.
