Optimum synthesis of steel plane trusses with subdivided panels

Abstract

Abstract.A computation scheme for topology and size optimization of steel trusses with subdivided panels has been developed. The framework strength, stiffness and stability limitations have been taken into consideration. The search for effective solutions is carried out on the basis of a genetic algorithm. An example of using the approach for optimization of the plane lenticular girder-type truss with 72 m span is given. A topology variant of the additional rods system for the truss panels and values of rod cross-sections for the whole structure has been obtained.
