Continuous beams have the capability to redistribute internal forces due to their indeterminate structural features, leading to enhanced beam deformability, reduced reinforcement congestion and more effective cross-section capacity usage. Thus, continuous reinforced concrete (RC) beams are popular members in most structures. However, RC structures located in corrosive environments might be degraded due to steel reinforcement corrosion. In this study, a recently proposed dual-functional intervention method, impressed current cathodic protection and structural strengthening (ICCP-SS), is adopted to repair degraded beams. The carbon fabric-reinforced cementitious matrix (C-FRCM) composite serves dual functions in the intervention method. The effects of reinforcement corrosion, cathodic protection and the C-FRCM strengthening system on the behaviors of continuous beams should be investigated. The aims of this study are to provide experimental data of continuous RC beams rehabilitated by ICCP-SS technology in corrosive environments and to investigate the structural responses, moment redistributions and design rules of these beams. This paper includes an experimental program, a discussion of the results and a design proposal. The results of electrochemical monitoring showed that the steel reinforcements in continuous beams under corrosive environments are successfully
