EXPERIMENTAL BRIDGE GIRDER OF REINFORCED PLASTIC

A girder suitable for a primary load-bearing component in a bridge structure and composed entirely of glass-reinforced polyester resin was designed, fabricated, and tested to failure under short-term static loads. The girder was designed with a solid flange and open web by classical procedures based on a pinned-end truss configuration. Reasonably close agreement was achieved between theoretical and experimental measurements. The web and lower chord elements were fabricated by "winding" continuous glass roving impregnated with polyester around preformed web stiffeners. Measured strains and deflections varied linearly with load. Structural failures usually occurred in joints formed with adhesives. An ultimate live load of 93 times the dead weight of the member was achieved for one of the specimens.
