Abstract: Application of ultra-high performance concrete (UHPC) in bridges has not been fully promoted due to the lack of the specification on bridge design using UHPC in China. A systemic research with an emphasis on experimental investigation and finite element analysis of UHPC beams is carried out in this study, focusing on the mechanical behavior, failure mode, crack resistance, and ultimate load carrying capacity. Total of 12 reinforced UHPC beams and 2 reinforced concrete (RC) beams are tested, taking steel fiber volume fraction and reinforcement ratio as the key parameters. Utilizing the general purpose program ABAQUS, the finite element model (FEM) for analyzing UHPC beam is established. The effect of different parameters on bending behaviors is investigated using FEMs, including steel fiber volume fraction, reinforcement ratio, yield strength of rebar, and compressive and tensile strength of UHPC. The calculation model is determined according to the mechanical behavior and failure mode of the reinforced UHPC beam.
