Seismic Vulnerability of the Concordia Temple

This work focuses on the seismic risk evaluation of the Concordia temple, situated in the Valley of the Temples in Agrigento (Italy). In the paper a general methodology to assess the seismic vulnerability, to be applied also to any kind of structures composed of stone blocks, is proposed. The vulnerability assessment has been conducted by means of equivalent nonlinear static analyses along the principal directions of the structure and the subsequent identification of equivalent single degree of freedom systems. Furthermore, the seismic vulnerability has been expressed both in a deterministic and a probabilistic context by evaluating the severe damage probability.
