The use of seismic isolation in bridges is considered as one of the most promising advanced technologies to enhance the structural safety during earthquakes. However, the method results in larger displacements of superstructure segments increasing the probability of pounding between them. Reports after severe ground motions show that the earthquake-induced structural pounding may lead to significant damage in isolated bridges. The aim of this paper is to analyze pounding between superstructure segments of a typical isolated highway bridge induced by the seismic wave passage effect. The analysis has been conducted on simplified lumped mass model with the simulation of collisions by impact elements. The results of the study confirm that pounding has considerable influence on the behaviour of the analyzed isolated bridge and may lead to the substantial increase in the structural response.
