Ancient temples consisting of classical columns have been exposed through the years to dynamic loads with sometimes detrimental effects. Predicting their dynamic behavior is important for their restoration and preservation. This paper analyzes the behavior of classical columns under dynamic loading using simplified two-dimensional finite element models. The adequacy of these models for the prediction of the dynamic behavior of classical columns is verified comparing the numerical results with experimental measurements. The most important parameters that influence the model’s behavior are identified. The behavior of classical columns can be predicted in the direction of excitation with reasonable accuracy using two-dimensional finite element models when the properties of the models are selected appropriately.

Preservation of the original architectural features of historic structures during their restoration and strengthening is challenging. A simple way to preserve the appearance of ancient classical columns and simultaneously protect them from earthquakes is to replace damaged or missing parts by a system that absorbs the incoming seismic energy. This paper examines the effectiveness of particle dampers in reducing the dynamic response of multi-drum and monolithic columns with capital. The properties of the damper that influence the column’s dynamic response were also examined with emphasis on the position of the damper. The measurements suggest that the replacement of the capital by a particle damper has small effect on the dynamic response of multi-drum and monolithic columns. The damper can enhance the column’s seismic safety if it replaces one of its top drums.
