This paper addresses the calculation of flexural moment capacities of reinforced concrete (RC) members rehabilitated with ultra-high performance concrete (UHPC) at the tensile zone. The prediction was based on a simple modification of current design codes. To compute the flexural moment resistance in the composite section, rectangular stress block diagrams for compressive and tensile zone of the normal strength concrete member and UHPC layer were assumed, respectively. Results showed that the proposed method could predict the flexural moment compared to test results.
