Abstract
Materials such as timber, concrete and steel have been utilised in the fabrication of transoms in railway bridges worldwide. Timber transoms are commonly used in Australia's railway network but frequently require maintenance and replacement due to the degradation of the timber. Therefore, they are not favourable for use in today's railway systems. To be a viable option for replacement, proposed transoms should provide practical, financial and structural benefits. This research outlines the structural benefits of composite steel-concrete transoms for ballastless tracks on the Sydney Harbour Bridge. The paper herein considers both reinforced concrete and prestressed concrete and simulates the derailment impact loading of a train through dynamic experimental testing. The paper also evaluates the potential use of 3 different shear connectors; welded shear studs, Lindapter bolts and Ajax bolts. The results of the experimental tests are used to determine whether each transom is a viable option for the replacement of the current timber transoms on the Sydney Harbour Bridge and whether they provide a stronger and longer lasting solution to the current transom problem.
