Abstract

The main aspect of seismic response of two adjacent multistory build- ings is their possible pounding due to an earthquake. Both buildings are treated as non-symmetric with respect to their mass and/or stiffness charac- teristics, so, when subjected to earthquake excitation, both buildings per- form the corresponding 3D motion. If the mechanical characteristics of buildings are different, buildings perform an out-of-phase motion so, if the initial separation of buildingss is not sufficient, occasional pounding between slabs of the same level is to be expected. The final result of collision be- tween buildings may be a substantial damage, or even worse, a collapse of buildings. Possible occasional pounding of buildings due to eart
