Abstract

Responding to the urgent need to replace pedestrian level crossings with footbridges on the UK rail network, a fibre reinforced polymer (FRP) bridge has been designed. This novel design incorporates a pretensioned, modified Warren truss structure formed from pultruded FRP sections. The pretension system ensures that the diagonal members in the Warren truss are always held in compression. This eliminates the need for bolted joints. To validate this design, a proof test was carried out, applying a load of 5.16kN/m2 to the bridge deck. The behaviour of the truss assembly was monitored with a strain gauges attached to the pretension system. This test demonstrated that the diagonal members remained in compression, validating the design analysis and proving the footbridge fit for purpose.
