Seismic response analyses of Parthenon's columns have been conducted to study their feasibility to safely withstand anticipated earthquake ground motions. The masonry columns were first modeled by lumped mass systems with both translational and rotational degrees of freedom. The rotational spring stiffness and the dynamic characteristics such as the natural periods of the columns were estimated by employing dynamic analysis of the microtremor records at Zeus-Olympeion Athens. Linear response analysis was performed to examine the earthquake resistant capacity against the synthetic ground motions corresponding to return period of 100 and 100 years. Furthermore, non-linear response analysis was carried out using an equivalent system with only translational degree of freedom. The analytical results indicate that Parthenon in existing state is not enough safe against the earthquake ground motion derived probabilistically for both return periods. The seismic loads may cause translational displacement at the interfaces of drums which compose the columns without any member on their capitals', In case that the pivots at the interfaces become ineffective due to weathering. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
