Several research studies have been conducted in order to investigate, through numerical simulations, the problem of earthquake-induced pounding of neighbouring buildings. A significant part of this numerical problem has to do with the simulation of impacts. The numerical modelling of impact phenomena and the estimation of the impact-forces acting on the colliding bodies is an important issue, not only for the cases of structural poundings, but also for other computational problems involving impact. In the current paper, a discussion is made on the various impact models that have been used in the scientific literature, while two new impact models are presented. This paper also examines the effect of using different types of impact models to simulate structural pounding on the overall structural response, since there is a logical question whether it would be valuable to improve the accuracy of an impact model, which is, after all, an oversimplification of the very complicate impact phenomenon.
