The effect of the column size and the effect of the input motion characteristics on the dynamic response of free standing columns are studied. Single columns and two columns coupled with an architrave subjected to a set of 20 ground motions are examined. The selection of the seismic excitations was made in order to provide a wide spectrum of structural damage due to statistical reasons. Further various prototype geometry sections are considered in order to include as key parameter the column size effect on the seismic behavior of these structural systems. Correlation study is performed to estimate the interrelationship between the most substantial ground motion parameters and the damage indices. Moreover the effect of the column geometry on the seismic response of classical column structural systems is studied based on the results of the linear regression analysis. Finally the relation between the maximum developed rotations and the residual displacements is examined. For the purposes of this study finite element models for the in space simulation of the members are adopted and results in term of relative rotations and relative residual displacements between the drums are presented.
