“…Further to the examples mentioned above, SHM via repeat testing and long-term monitoring has been applied to different forms of FRP road bridge. These include bridges with timber decks on FRP beams [19,20], GFRP decking on FRP beams [21,22,23], sandwich FRP decks [24][25][26][27][28], FRP decks on steel beams [29][30][31][32][33][34], a hybrid FRP-concrete arch bridge [35] and a concrete deck on FRP beams [36]. Instrumentation comprised various combinations of strain gauges, deflection transducers, accelerometers and impact hammers.…”

The Frampton Cotterell FRP road bridge deck comprises pultruded GFRP units which are laid longitudinally and are adhesively bonded transversely, in contrast to previous GFRP deck bridges where the pultruded units were laid transversely. This novel layout dictates that transverse distribution of live loading occurs only through the deck's flanges and entails possible transverse tension which should be controlled to avoid cracks through the bonded deck-deck joints. The present paper assesses these structural actions by interpreting strains and deflections recorded during lorry testing of the bridge. Transverse distribution is evaluated by comparing transverse profiles of recorded longitudinal strains and predicted longitudinal moments, with the conclusions qualitatively reinforced using a deflected surface based on the test recordings. Evidence of the deck acting as a continuum free of propagating joint cracks comes from the fact that the strains recorded during complementary lorry runs along the bridge satisfy the superposition principle, and that the recorded strain influence lines replicate an idiosyncratic feature of the moment influence line without redistribution effects. That feature was then exploited to inform the strategy for a braking test which produced valuable vibration data for the bridge. Test data integrity is corroborated by cross checking deflections recorded from different types of sensors. It is concluded that since longitudinal placement of pultruded decks enhances the versatility of FRP bridges, this sensor layout and data interpretation process may form part of a wider strategy for health monitoring of such bridges.

“…FRP deck bridges are a relatively recent innovation, so research is needed to understand key facets of their global and local structural mechanics. To date global features such as dynamic performance, transverse load distribution and deck-beam composite action have been studied via analysis along with lab and field studies [9][10][11][12][13][14][15][16][17][18][19][20]. Even for more conventional (e.g.…”
