DOI: 10.1080/00423114.2017.1398341
Abstract: ABSTRACT Derailments on bridges, although not frequent, when occurs due to a complex dynamic interaction of the train–track–bridge structural system, are very severe. Furthermore, the forced vibration induced by the post-derailment impacts can toss out… read more here.
