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 ...
