ABSTRACT

An approach is presented for the optimization of steel truss by combining evolutionary algorithms and
commercial structure analysis program. Genetic algorithms (GA) have been shown to be effective optimization
tools for practical optimization problems. The use of nonlinear finite element can assist greatly in achieving a safe
design. However, commercially available finite element programs are not designed for optimization tools. ‘Home-
written’ structure analysis program can be designed to achieve this task, but it may suffer from serious drawbacks
such as bugs, lack of user friendliness, lack of generality, and unproven reliability. The purpose of this paper is to
discuss combining SAP2000 structure analysis program with genetic algorithm for optimizing steel truss structure.
The implemented method is tested on 10 members of 2D steel structure, 25 members of 3D steel structures and 72
members of 3D steel structure, where the results are compared with previous researches. It is concluded that this
method can serve as a useful tool in engineering design and optimization.
