This paper presents a numerical study of the seismic response of ancient columns. The multidrum column analysed here corresponds to the Hellenistic portico of Lindos acropolis. This structure was modelled using a finite element model, which also included its base. The simulations were made in three dimensions. Extensive time domain parametric analyses were performed in order to examine the behaviour of the column subjected to seismic motion having different values of peak ground acceleration. The seismic input used consisted of horizontal components of three earthquakes, with different frequency content. Three different systems connecting the drums of the column are analysed in order to examine their influence on the seismic response of the column. Our study takes into account the complex behaviour of the structure with the aim to determine the PGA value that is the threshold before its collapse. Finally, we present a procedure to estimate the dominant period of a monolithic, a multidrum, and two multidrum columns connected with an architrave from microtremors measurements. The results of the microtremor measurements are compared with the numerical simulations to assess the effectiveness of the procedure. Our results show that microtremor measurements are useful to estimate the modal shapes of ancient columns. Code: *************************************** |
