Keywords: impact, impact velocity, dissipated energy, damping..

Summary

Building pounding has been recently studied by different researchers around the world to evaluate the 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 the dissipated energy during collision.

In this paper, the steady state response of single degree of freedom system as a result of the external force has been evaluated. The impact damping ratio from viscose damping was calculated to simulate the nonlinear viscoelastic model and the results of the impact were compared with other similar impact damping ratios, suggested in previous studies. Here, a new equation of motion is presented to obtain the best available estimation of the impact damping ratio and is also simulated to compute the impact force during seismic excitation.
