Effect of the seismic excitation angle on the dynamic response of adjacent buildings during pounding
Polycarpou, Panayiotis C.; Papaloizou, Loizos; Komodromos, Petros I.; Charmpis, Dimos C. (2015)The excitation angle or angle of incidence is the angle in which the horizontal seismic components are applied with respect to the principal structural axes during a time history analysis. In this study, numerical simulations ...

Two-dimensional numerical investigation of the effects of multiple sequential earthquake excitations on ancient multidrum columns
Papaloizou, Loizos; Polycarpou, Panayiotis; Komodromos, Petros I.; Hatzigeorgiou, George D.; Beskos, Dimitri E. (2016)Ancient monuments of Greek and Roman classical architecture usually consist of multi-drum columns that are constructed of stone blocks placed on top of each other. Several research studies deal with the seismic behaviour ...
