Earthquake-induced structural pounding between insufficiently separated build-ings, or bridge segments, has been repeatedly observed during ground motions. The reports after earthquakes indicate that it may lead to some local damage in the case of moderate seismic events or may result in considerable destruction or even collapse of colliding structures during severe ground motions. Pounding in build-ings is usually caused by the differences in dynamic properties of structures which make them vibrate out-of-phase under seismic excitation. On the other hand, in the case of longer bridge structures, spatial seismic effects related to the propagation of seismic wave are more often responsible for collisions between superstructure segments during earthquakes. The aim of the book is to analyse different ap-proaches of modelling the earthquake-induced structural pounding as well as to the show the results of the studies on collisions between buildings and between bridge segments during ground motions. The aspects related to mitigation of pounding effects as well as the design of structures prone to pounding are also dis-cussed.
