The seven-story reinforced concrete building studied in this work was damaged during the 1994
Northridge, California earthquake. The damage was widespread but was mostly concentrated in
the columns on the fourth floor, below the spandrel beam and the floor slab on the fifth floor. We
show that such a concentration of damage can be explained by interference of non-linear waves
in the building resulting from incident, upward-propagating earthquake pulses and downward
propagation of pulses reflected from the roof of the building. We conclude that the analysis and
prediction of where the localized damage may occur and the proper design to minimize and
control such damage can be carried out best by non-linear wave propagation methods.
