Abstract

In this paper, the experimental results of a multiblock column have been demonstrated by the harmonic and cyclic impulse movements of the base. The tests were performed on a shaking-table with one degree of freedom at the Materials Testing Laboratory “M. Salvati” of the Polytechnic University of Bari for the rigid and deformable foundation column. Through the use of 3D printing, a staircase prototype of 6 blocks along the stem plus the capstone was built, with a base-diameter ratio of 6.5. Geometric features represent a “standard” column belonging to the classical Doric order in the Mediterranean basin. The main aim of this paper was to study the influence of deformability of the foundation on the overall dynamics of the phenomenon in order to address operational solutions that reduce the seismic vulnerability of such structures that are technically and technologically compatible with the current archaeological culture.
