Optimization of plane frames with changing cross-section

Abstract

Structural optimization is a new field of mechanical research. It is a combination of mechanical computation and mathematical optimization. So the optimization process is a numerical computation. With the development of computing technology on computers, it is more convenient than ever to calculate large systems to solve optimization problems. The author builds and successfully solves the optimization problem of flat frames by force method with constant cross section and variable column cross section. Building algorithms, designing block diagrams and programming to build optimization problems of flat frames by force method on Matlab programming language. Calculation results with comparison of manual calculation, programming and reference are error-free.
