ABSTRACT: The present contribution reviews the already classical transformations of seismic input energy
into multi-story structures and emphasizes the less developed distribution of this energy to the natural modes of
vibration. The computation is conducted on two scaled down steel multi-story frames dynamically modeled as
mdof systems. The main objective
