It has long been of interest for railway engineers to determine the dynamic response of beams or girders resulting from the passage of moving vehicles across the span. The phenomenon is called 'impact' and extensive studies have been performed in this field. Various kinds of formulae or factors have been adopted in design codes to cover the practical application. The authors re-examined the design formula of impact for concrete railway bridges to make it applicable to the cases that vehicles have different wheel bases and different maximum velocities. Proper impact factor may be taken from the proposed formula within the widen range of velocity parameter from the study.
