OPTIMAL SIZE-AND-SHAPE SYNTHESIS OF SYSTEM OF STRENGTHENING OF STEEL TRUSSES

Cover Page

Abstract


The computing circuit for search the optimal size/shape of structural design to improve the bearing capacity of metal trusses based on the evolutionary modeling is developed. We considered strengthening by increasing the rod cross section and a change structural layout of the object. The topology formation is performed based on exception of some redundant rods of structure and a change position of nodes. By increasing of cross section rods the strengthening is modeled by introducing finite elements with hard consoles. Optimization is carried out by path the minimum cost of structures. The examples of strengthen in truss equipment building overhead cranes and increase operational load on the roof is given.
