# Modelling of Structural Pounding

## Abstract

Modelling of earthquake-induced pounding between buildings, or bridge segments, requires the use of accurate structural models as well as appropriate models of the effects of collisions. Two different approaches can be found in the literature, which are usually used to simulate structural pounding during ground motions. The first approach considers the classical theory of impact, which is based on the laws of conservation of energy and momentum and does not consider stresses and deformations in the colliding structural elements during impact. Since this is not a force-based approach, the effect of collisions is accounted through updating the velocities of the considered bodies or structural elements. In the second approach, the earthquake-induced structural pounding is simulated using the direct model of impact force during collision.
