Abstract:

***EACH PAPER IS TREATED LIKE A SEPARATE DOCUMENT AND MAY BE VIEWED AND/OR DOWNLOADED THAT WAY*** One of the impediments to the expansion of the use of fiber-reinforced polymer (FRP) composites for the rehabilitation of structures is the lack of design standards, which is the subject of this workshop. By bringing together researchers from academia, practitioners from industry and regulators from government, it aims at providing a snapshot of the state of the practice and establishing research needs to develop national standards on the use of FRP composites for the rehabilitation of concrete and masonry structures. The workshop included a plenary session where nine speakers defined the issues and established a framework for the discussion. Next, participants broke out into three separate sessions, on columns, beams and slabs, and walls, respectively. Areas in need of further research include anchorage of FRP to beams and walls, ductility of beams and walls reinforced with FRP, durability, material safety factors, fire resistance, and nondestructive evaluation methods for quality assurance of field installation. The workshop participants encouraged NIST to be active in researching solutions to all the above issues and to work closely with standards writing organizations, such as ACI, ASTM, ASCE, AASHTO in developing the technical bases for standards for the use of FRP composites in the rehabilitation of civil infrastructure. In particular, the participants would like to see NIST take a leading role in tests of FRP-reinforced concrete and masonry structures subjected simultaneously to fire and loads; to serve as a national data center for FRP material properties, laboratory tests and field performance; and to develop a comprehensive Handbook on Structural Repair with FRP similar in scope to the EUROCOMP Design Code and Handbook (1996).
