PERFORMANCE OF TUBE AND PLATE FIBERGLASS COMPOSITE BRIDGE DECK
A composite bridge deck system assembled from glass/polyester pultruded components has been developed. This system utilizes square tubes running transverse to the traffic direction, mechanically fastened and bonded together, and flat cover plates bonded to the tubes with an epoxy adhesive and through-anchored to the deck support structure using mechanical connectors. A 4.27 by 1.22 m section of the deck system integrally connected to the superstructure at a 1.2 m girder spacing was tested to failure under a single patch loading. The results indicte a factor of safety of 4 on strength and a deflection-to-span ratio of ~L/300. Another section of the deck was fatigued to 3,000,000 cycles under service loading at a load ratio of R = 0.1 and a nominal frequency of 3 Hz. Results from these tests indicate no loss in stiffness up to 3,000,000 cycles. Following the fatigue testing, this section was also tested to failure; no loss in strength was observed. In addition, a finite-element model of the laboratory tests was developed. Results from the model showed good correlation to deflections and longitudinal strains measured during the tests.
