Evaluate the Effectiveness of the use of, Viscoelastic Damper on the Behavior of Steel Structures

Today, the use of seismic dampers to control vibrations of the structure against earthquake forces, as depreciated energy systems, while concentrating inelastic deformations, during an earthquake, in these systems, ease finds, as well as the repair and rehabilitation of structures. In this method, be used as a method of controlling structures. So, to review the results of using this method, the performance of steel structures, steel building, is modeled on the 12 floor, and a three-dimensional, and the increase in viscoelastic damper, the structural analyzes of is, in terms of time histories, acceleration, and displacement of the roof, and the relative displacement stories, have been investigated. The results show that, this method has caused reductions roof displacement. Comparison of all results is presented in the context of this paper
