Effects of pulse-like earthquake motions on a typical subway station structure obtained in shaking-table tests

•Large-scale shaking-table tests were carried out for a subway station structure.•Effects of velocity-pulse parameters on structural responses were studied.•Velocity pulse increases the amplitude of soil first-mode shear-type deformation.•Multiple pulse cycles may trigger remarkable resonance-like p...
