Abstract:
Optimizing of structures in civil engineering will be observed if designing will be technical and implementation cost will be affordable.On the other hand ,according to different application of trusses in construction projects and importance of lightening, always appropriate methods have been considered by the engineers these days.Optimizing of truss structures by genetic algorithm was first introduced in 1386. In the past, to optimize the size, shape and topology of two-dimensional and three-dimensional trusses, both classical method of forces and genetic algorithm was used to optimize truss structures.However, different criteria can be considered, but usually various criteria are influenced by one of them. In other words, with the optimization of those criteria, others are being pushed towards its optimal state. In truss structures you deal with a series of bars, for this case almost all design parameters of truss are influenced by the cross section area of this bar. Therefore, different criteria are influenced by the weight of truss. In this article, in addition to observing possible states for determining the optimization of trusses, also tried to get a minimum weight structure that can provide all predicted design constraints.
