ABSTRACT
The paper presents results obtained by experimental in situ dynamic testing of two similar Imperial Age monuments built of white marble blocks, located in Rome’s historical center: the Column of Trajan and the Column of Marcus Aurelius. Experimental testing is the first phase of a project for evaluation of seismic behaviour of the column of Marcus Aurelius, performed in cooperation between Institute of Earthquake Engineering and Engineering Seismology, University St. Cyril and Methodius, Skopje, Republic of Macedonia and Istituto Nazionale di Geofisica, Rome, Italy. The dynamic properties of the columns have been investigated in terms of natural frequencies, mode shapes, damping coefficients and soil-structure interaction.
