Περίληψη:	Classical monuments are often founded upon deposits of very soft soil or upon the debris of ancient cities, the deformability of which can significantly affect their seismic response. Focusing on monuments which are prone to experiencing overturning failure, the role of soft soil on seismic performance is investigated through dynamic time history analyses using nonlinear finite elements. Inspired by “Triumph Columns”, monuments of Roman origin that are widespread across the Mediterranean, the paper presents a parametric analysis of inertial loads, drift demands and permanent deformations exerted upon columns founded on idealized soil profiles of strikingly different stiffness characteristics. Ricker pulses of varying acceleration amplitudes and frequencies are used as bedrock excitations. Comparative presentation of results from 72 dynamic analyses indicates the dominating effect of soil nonlinearity. Acting as a double fuse, the latter can first attenuate the seismic motion that reaches the ground surface and then cut-off the inertial load transmitted on the superstructure. The unavoidable shortcoming is presumably associated with permanent deformations of the soil-foundation interface, especially settlements.
