Main goal of present study is optimal design of three dimensional flexural frame with using genetic algorithm. Genetic algorithm, it is an evolutionary algorithm based on intelligent search and it is highly efficient in discrete decision making. Also, in this respect, it may be appropriate to optimize the steel frames with the available profiles in the market. In terms of control design restraint, OpenSees software for determining response of structure was used. In continue, OpenSees results with genetic algorithm connected with using Matlab software. Design methodology in this research is LRFD. Also, in present study three dimensional frame including a frame with six stories, two frames with 10 stories under gravity, seismic and wind loads have been expanded. In optimal processing, frames with and without construction restraint analyzed and both of results have been proposed. Results of present study showed that optimal model have high applicable in proposing optimal design.
