In this study, as-recorded sequential ground motions including the mainshock and at least one aftershock are employed for carrying out nonlinear time history analyses since those seismic sequences represent the real correlation between the mainshock and the aftershock and would not overestimate the structural response significantly in comparison with artificial seismic sequences [22].
