A design method has been developed that can be used for calculating the shear strength of both steel and fiber-reinforced polymer (FRP) reinforced concrete members. While this procedure has been shown to be an effective method for rectangular sections, this investigation explores its applicability for the design of flanged sections. Several design approaches to provide extension of the method are subsequently developed. The range of applicability of the various approaches is illustrated by comparing the computed results with the test results of 154 T-beams and 370 rectangular beams. In general, the proposed design equations provide reasonable and conservative calculations of shear strength for beams in both the T-beam and rectangular beam databases. The results from the proposed methods are also compared with those using the current ACI design procedure to provide perspective on the benefits of the procedure. Based on this study, recommendations are provided for a simple and consistent method that can be used for the calculation of shear strength for both rectangular and flanged sections.
