Multi-span gable frame structures shows significant cubic effects that may reduce the displacements and stress resultants of the frame. The optimal weight may express not only a literal design standard of a structure but also a quantitative evaluation of the cubic effect of the structures. Then, adopting the genetic algorithms to optimize the weight of the multi-span gable frame structures that have a same plan and height of eaves but have various gable frame pitch and beam pitch, we examine the minimum weight design of the structures and the cubic folded plate effects on the design. It takes much computing time, when the genetic algorithms is applied to the design. In order to reduce the computing time, we adopt equivalent beam theories of the multi-span gable frame structures.
