Abstract :
    One of the objectives of seismic design is the control of damage to structures due to severe earthquakes Which even reveals the structure s attitude of increasing the structural strength to increasing the ductility of the need to pay attention to the seismic assessment of the structure with respect to the attitude of ductility capacity. The use of elements for increasing the inertia and loss of seismic energy is the kind of attitude that is performed by the dampers.Which is different for each project to be designed. In this study, the construction of 4-8-12-steel buildings with three 5-meter spans with a converging bracing system with and without friction damper is based on the 2800 Editorial Rev. 3 with increasing dynamical analysis and modeling with the sap 2000-v 18-Etabs software. the payment.
