The use of externally bonded fiber reinforced polymer (FRP) composites to repair, strengthen, and seismically retrofit structural components of existing buildings and infrastructure has been steadily on the rise. However, more research is needed to assess 1) the extent of structural performance improvements after application of FRP composites and 2) how FRP composite performance changes over time. In FY 2018, researchers from the Earthquake Engineering and the (now) Infrastructure Materials Group in the Materials and Structural Systems Division initiated the FRP composite project to improve the state of practice for design and evaluation of FRP-retrofitted structures. The project team hosted a workshop of national experts in May 2018 to identify material and structural level research needs concerning the use of FRP composites in repair and retrofit of structures. In this presentation, the project team will present (1) the project overview, (2) the prioritized research needs (3) the internal NIST research plan and (4) the progress of the research tasks to-date. The presentation will specifically cover the research tasks concerning development of FRP-retrofitted shear wall design guidelines, accelerated weathering and outdoor weathering studies of FRP composites bonded to concrete, field studies, and in-situ tests for performance evaluation of FRP composites.
