Abstract: Flexural behavior of composite girders consisting of hybrid fiber reinforced polymer (HFRP) I-girders and ultra-high performance concrete (UHPC) slabs was experimentally investigated. The HFRP I-girders consisting of layers of carbon fiber reinforced polymer (CFRP) and glass fiber reinforced polymer (GFRP) were employed in the experimental investigation. The composite girders were tested under four-point loading scheme. The results showed that the composite girders could provide a very competitive and sustainable solution to accelerated bridge construction. A three-dimensional nonlinear finite element (FE) analysis of simply-supported HFRP-UHPC composite girders was carried out. Nonlinear load-slip relationship for the shear connectors was considered in the FE analysis. Comparisons between the experimental and FE analyses were performed and a fairly good agreement was found.
