• A lot of bridge reinforcement and rehabilitation projects are been implementing throughout China and many countries in the world. However, some fundamental questions still remain unsettled, and this paper addressed one of them, which is the bearing capacity of strengthened beams. We analyzed the loading process of beams after strengthening with strain lag effect, and focused on several critical states. To validate our conclusions, we developed a non-linear FEM program, and compared the data yielded by program with those from reference. We found that for adequate reinforcement RC beams the influence of strain lag effect on the bearing capacity depends on the property of reinforcing material. The conclusion matched with experiment very well.
