Baukastensystem für CFK-Fachwerkstrukturen – Diskrete Optimierung der Strebenquerschnitte

Abstract

Fiber-reinforced plastics have a high potential for lightweight structures due to their high specific strength and stiffness. A modular system enables a reduction of the manufacturing costs for trusses by standardizing the components. The subdivision of the truss struts into groups and the selection of the profiles for the strut groups can be done by optimization with a genetic algorithm and the initial population generation by the bisection method. The proposed method reduces the number of necessary iterations and improves the optimum in comparison to the previous descriptions.
