An experimental study was conducted at the Ferguson Structural Engineering Laboratory in order to investigate the shear behavior of 54-inch deep prestressed concrete U-beams. The primary goal of this research was to improve the design and detailing of the skewed end-blocks commonly used in these beams. As U-beams had been in service for several decades without incident, it was anticipated that there would be little need for change in the design, and the findings of the research would involve a slight tweaking to improve the overall performance. Unfortunately, during the first phase of shear testing (testing of the current design standard) it was found that the U-beam was not reaching the code calculated shear capacity. During this phase of testing the premature failure mechanism was isolated as the breakdown of the web-to-flange interface in the end region of the girder. Therefore, the second phase of testing sought to prevent the breakdown of this boundary by three options: (1) increasing the web width while maintaining current levels of mild reinforcement, (2) increasing the web width while also increasing the amount of reinforcement crossing the web-to-flange boundary, or (3) by increasing the amount of reinforcement at the boundary while maintaining the current web width. Two acceptable solutions to the premature failure method were developed and tested during this phase both of which included an increase in the amount of mild reinforcement crossing the web-to-flange interface (with and without an increase in web width). The research into refining of these new details is ongoing as part of the Texas Department of Transportation's Research Project number 0-5831.

Many studies conducted on the use of Fibre Reinforced Polymer (FRP) sheets for shear strengthening have been completed on beams that are small in relation to the effective bond length of the FRP. This study focuses on the use of FRP sheets for large-scale concrete members. Two series of large scale concrete beams were strengthened in shear to develop a better understanding of the behaviour of FRP shear strengthening on large specimens and to develop a means of predicting the shear capacity for all sizes of members. The first series of three specimens were obtained from a full sized I-section prestressed concrete bridge girder. One of these specimens was tested as a control, with the remaining two strengthened for shear with different configurations of Carbon Fibre Reinforced Polymer (CFRP) sheets. To develop a better understanding of bond behaviour of large-scale specimens, three reinforced concrete T-section beams were fabricated with a web height that was larger than those found in the literature. One of these beams was strengthened in shear using Glass Fibre Reinforced Polymer (GFRP) sheets and two others were strengthened using CFRP sheets. These beams were tested under static loading conditions. (Abstract shortened by UMI.).
