چکیده :

Using genetic algorithms to design a building frame section, is a science that can check the behavior of structure against the criteria for algorithm changes, infeasible problem, sections range, type of frame, type of loading and the way to apply them. To achieve the specified outputs, we should define a function for the considered algorithm based on infeasible condition to gain the special purpose. In the current study, we attempted to find a structural mechanism using, three types of moment frame under different circumstances. Regarding the obtained results in our analysis, some of the studied criteria have been considered fixed; moreover, the effect of one variable on structural mechanism with plastic hinge formation has been examined. The collapse load factor has been calculated in formation mechanism of the analysis, which according to the defined constraints of the algorithm will obtain the maximum collapse load factor from every population formed. Finally, the frame performance is investigated based on different characteristics such as collapse load factor, number of hinges, displacement and type of the formation mechanism.
