Abstract

The seismic behaviour of ancient monumental structures with monolithic or multi-drum classical columns and colonnade systems in two rows is investigated. In particular, the Discrete Element Method (DEM) is utilized in the study of ancient columns under strong ground excitations, by simulating the individual rock blocks as distinct bodies. A specialized software application is developed, using a modern object-oriented programming language, in order to enable the effective simulation of multi-drum columns and colonnades under harmonic and earthquake excitations. The results obtained by the developed software are compared with results from analytical equations of motion of rigid blocks, so as to validate the software. A large number of parametric studies is performed in order to investigate the effect of excitation characteristics as well as the influence of geometrical and mechanical characteristics of multi-drum columns on their behaviour and response under harmonic and earthquake excitations. Furthermore, colonnade systems with epistyles, as well as, with two rows of columns, one over the other, are examined with earthquake ground motions.
