Abstract:
The design principle of fiber-reinforced polymer (FRP) reinforcing composite bars for concrete structures
has been well established through extensive research and field practices. Provisions governing certification testing
and evaluation as well as quality control/assessment and FRP design provisions, are now in place to regulate materials
specifications and design aspects and guide FRP manufacturers and end-users. The Canadian Standards Association
(CSA) group addressing the state-of-the-art FRP material specifications and design requirement recently issued two
updated provisions. The new edition of CSA S807 includes several additions and modifications in terms of quality
and qualification requirements, material properties, testing procedures, and material mechanical and durability
limitations. Additionally, the updated Section 16 of CSA S6 for the design of fiber-reinforced structures and highway
bridges aimed at providing more rational design algorithms and allowing practitioners to take full advantage of the
efficiency and economic appeal of FRP bars. This paper presents a summary of these recent modifications in Canadian
codes and standards, introducing the underlying rationale. Additionally, the paper highlights the recent field
applications of FRP bars in different types of concrete civil-engineering infrastructure.
