Abstract:
New research funded by the ACI Foundation developed and tested retrofit techniques for diaphragms using externally bonded fiber-reinforced polymer (FRP). Key findings from the research are being translated into guidance on how to establish the effective FRP design strain and the nominal shear strength contribution of the FRP. The recommendations also address the use of intermediate and end FRP anchors and limitations on the clear spacing between sheets
