title = "Strength of Rc Beams with an Frp-Strengthened Web Opening",
abstract = "Web openings often need to be created in existing reinforced concrete (RC) beams for the passage of utility ducts and/or pipes. Such web openings lead to significant decreases in the load-carrying capacities of the beams due to the reduced cross-sectional area and/or severing of some of the existing stirrups. Therefore, an externally bonded fiber-reinforced polymer (FRP) strengthening system is often applied around the web opening to ensure the safety of the weakened beam. A number of existing experimental and numerical studies have provided useful information on the structural behavior of RC beams with an FRP-strengthened web opening. However, it is desirable to develop a simple strength model for RC beams with an FRP-strengthened web opening, if only the strength of such beams is of concern. This paper proposes a strength model for RC beams with an FRP-strengthened web opening for engineering use. Test results are compared with the predicted results using the proposed strength model to verify the accuracy of the model. A good agreement between the predicted and test results is obtained and therefore the proposed strength model is recommended for engineering use.",
