“Application of fiber reinforced polymer (FRP) pultruded sections for civil engineering applications in infrastructure is rapidly increasing. Composite members may potentially provide more durable replacements for steel and concrete in primary and secondary bridge structures, but significant amount of work still needs to be done before the application of composites in infrastructure applications can become a routine. This research work contributes towards achieving that goal.
An extensive experimental and analytical program was carried out to obtain and compare properties (stiffness, strength, failure modes) of 76 mm (3 in) square hollow pultruded glass FRP tubes and their assemblies which were used in the fabrication of an all-composite bridge deck designed for H-20 truckloads as specified by the American Association of State Highway and Transportation Officials (AASHTO). All the coupons were tested in three- or four-point bending. Experimental results show excellent linear elastic flexural and shear behavior up to failure. A quarter portion of the full-size bridge deck was then tested for its structural performance under design and fatigue loading and also for ultimate load capacity to evaluate the bridge response under H-20 loading. The characteristics of the full-size bridge deck were determined by analyzing the tests performed on relatively smaller sections of the same design.
Based on results of the present research, all-composite bridge decks made of pultruded glass and carbon FRP tubes is judged to be a suitable replacement for bridges made of conventional materials”—Abstract, page iv.
