The structural vibration system has been taken into consideration to boost the dynamic performance subjected to earthquake. The viscoelastic damper is considered to be as an inactive damper, dissipating the energy imposed to the structure through fluid turbulence. The fluid viscoelastic dampers are adequate devices to improve the overall structural performance through the reduction of demanded deformation and force, because of its substantial energy dissipation capacity. Therefore, it is believed that the viscoelastic dampers come out with satisfactory performance subjected to impact loading. This paper investigates the performance viscoelastic dampers under explosive loading, through presenting the dynamic behaviour of the steel moment frames, with and without dampers. The fundamental design of structures subjected to shock pulse excitations also are discussed. For this purpose, two, five and ten story frames, each one with three and five spans, were considered using nonlinear dynamic analysis through OpenSees software. The results indicated that the maximum displacement of roof was decreased by around 50 percent in frames retrofitted by viscoelastic dampers. In addition, the results showed that the maximum base shear parameter is significantly dependent on the explosive intensity rather than the number of stories or bays in frames with viscoelastic dampers.
