This books analyzes different approaches to modeling
earthquake-induced structural pounding and shows the results of
the studies on collisions between buildings and between bridge
segments during ground motions. Aspects related to the mitigation
of pounding effects as well as the design of structures prone to
pounding are also discussed.

Earthquake-induced structural pounding between insufficiently
separated buildings, and between bridge segments, has been
repeatedly observed during ground motions. The reports after
earthquakes indicate that it may result in limited local damage
in the case of moderate seismic events, or in considerable
destruction or even the collapse of colliding structures during
severe ground motions. Pounding in buildings is usually caused by
the differences in dynamic properties between structures, which
make them vibrate out-of-phase under seismic excitation. In
contrast, in the case of longer bridge structures, it is more
often the seismic wave propagation effect that induces collisions
between superstructure segments during earthquakes.
