Abstract (EN): Building pounding has been recently studied by different researchers around the world to evaluate impact between two adjacent buildings. Numerical studies are an important part of impact, in which several researchers have tried to simulate the impact by using different formulas. Estimation of the impact force and the dissipated energy depends significantly on some parameters of impact. Mass of bodies, stiffness of spring, coefficient of restitution, damping ratio of dashpot and impact velocity are some known and unknown parameters to simulate the impact and to measure dissipated energy during collision. In this paper, a mathematic part of steady state response of single degree of freedom system due to the external force has been evaluated. Impact damping ratio due to viscose damping was calculated to simulate nonlinear viscoelastic model and the results of impact were compared with other similar impact damping ratios, suggested in previous studies. Here, a new equation of motion is presented to get the best available estimation of impact damping ratio and is also simulated to compute impact force during seismic excitation.
