A detailed experimental programme was conducted to investigate the structural behaviour of rebar-reinforced ultra-high-performance concrete (UHPC) beams subjected to pure bending and combined bending and shear. Four flexural bending tests and four bending–shear tests were conducted and four different reinforcement ratios (1·09%, 2·75%, 3·60% and 4·99%) were used. The bending characteristics of the rebar-reinforced UHPC beams under static loading were assessed, including cracking, failure patterns, deflection, ductility and flexural capacity. The influence of the reinforcement ratio on the flexural performance of the rebar-reinforced UHPC beams was observed and analysed. A model was developed for predicting the ultimate flexural capacity of rebar-reinforced UHPC beams. The adequacy of the prediction model was assessed using experimental data from the current study and the published literature, and the results showed that the model can be used to estimate the ultimate flexural capacity of rebar-reinforced UHPC members accurately. The results of this study provide valuable information for a comprehensive understanding of the structural behaviour of rebar-reinforced UHPC members.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
