Abstract:

Production of High strength steel (HSS) with well ductility and weldability has been developed in recent 50 years. Usage of HSS did not expanded, because civil engineers were not familiar with them. Until their characteristic and their performance in cyclic loading are not being studied, their final usage will not be expanded. So in this research, rigid connections have been modeled by finite element software Ansys and have been applied to quasi-static cyclic loading. The results show that, using HSS reduced ductility only 30 percent and this reduction can be counteracted by increasing allowable stress in High strength steel.
