The comparison of portal frame design by penalty function optimization and traditional method aim at 30m span portal frame with tapered members was made. It was found that the essence of optimization design was to research the reasonable distributing of sections, through the interaction between capacity and key section parameters the optimization design were realized. Now the idea of green and less energy is fashionable, then optimization design is very significant in practical engineering. According to engineering statistics the optimization design can reduce 15%~30% of material quantity. In this article the selection of parameters during optimization design was expounded. © (2012) Trans Tech Publications.
