THE UK'S FIRST FOOTBRIDGE REINFORCED WITH GLASS-FIBRE RODS

This article describes the design and construction of a footbridge at Chalgrove, Oxfordshire, England, which is being reinforced with glass-fibre composite rods instead of the usual steel. It is one of the demonstration structures being built as part of Eurocrete, a pan- European collaborative programme to develop fibre composite reinforcement, with support from EUREKA. Oxfordshire County Council provided the opportunity to build the footbridge, to replace an existing timber bridge that had deteriorated. Access to the site was good, allowing relatively easy construction and subsequent monitoring. The bridge was designed as one 5m long by 1.5m wide slab, with 13.5mm diameter glass-fibre reinforcement on its top and bottom faces. The main design criteria were deflections and control of early thermal movements. The slab was placed on abutments constructed earlier, and handrails were fitted later. Various load tests were performed on the bridge, in accordance with British Standard BS8110; they confirmed the design assumptions, and will be repeated after six months and one year. Vibrating wire gauges, thermocouples, and fibre optic gauges have been fitted, to monitor the bridge.
