Abstract:The permissible crack width of concrete members reinforced by reinforcing steels is generally determined by the durability of the member based on reinforcing steel corrosion. However, since FRP reinforcement does not corrode by rusting, another factor should control permissible crack width for FRP reinforced structures. Paper examines permissible crack width of FRP reinforced concrete members in terms of the esthetics of external appearance. As cracks are wider, appearance deteriorates. Since esthetic evaluation is subjective, the authors used a questionnaire survey to gather information from experts. The surveys were completed by members of the JSCE Research Subcommittee on Continuous Fiber Reinforcing Materials. After reviewing a statistical analysis of the results, the authors offer estimates for permissible crack width of FRP reinforced concrete members.
