Flat rod systems: optimization with overall stability control

Igor Serpik, Anatoly Alekseytsev, Pavel Balabin & Natalia Kurchenko
An algorithm for discrete optimization of steel flat rod systems was developed on the basis of an evolutionary search. The task is to minimize the weight of the bars via taking into account constraints on stresses, displacements, and overall stability. The cross-sectional dimensions of the bars and the coordinates of their node connections were varied. Buckling is taken into account when stability is lost both in the object plane and out of the plane. Analysis...
