Abstract

Pultruded Glass Fibre-Reinforced Polymer (GFRP) materials are light, durable, strong and can be fabricated economically, providing a great advantage in the area of civil construction. A team at Monash University has constructed a 9 m long pultruded GFRP footbridge to investigate the feasibility of such structures. This paper presents an experimental investigation into the static performance of pultruded FRP composite bridge under uniformly distributed load. A sandwich bridge deck was fabricated using pultruded GFRP box-profiles, adhesively bonded between two GFRP flat plates, supported by two pultruded GFRP I-beams underneath. Bidirectional pultruded profiles with 6 mm-thickness and 9 mm-thickness are used in longitudinal and transverse pultrusion orientations to optimize strength and stiffness, and prevent any local failures. Extensive material testing and full-scale structure testing were carried out to establish the overall structural behaviour accurately. Deflection response, composite action, and bond performance were examined under three span configurations: 9 m and 6 m single span and a 4.5 m continuous span.
