Flexural and cracking behaviors of reinforced UHPC beams with various reinforcement ratios and fiber contents

•Nine large-sized reinforced UHPC beams are fabricated and tested under flexure.•Steel rebar and fiber play a significant role in limiting the crack development of UHPC beam.•A high-precision model is developed to predict the average crack spacing of UHPC beam.•Flexural capacity of UHPC beam increas...
