Abstract
AbstractThis paper presents the issues and solutions in developing design codes and standards for the use of fibre‐reinforced polymer (FRP)‐reinforced concrete structures. First, the codes for new construction, referring mainly to the Japan Society of Civil Engineers (JSCE) Recommendations for Design and Construction of Concrete Structures using CFRM (Continuous Fibre Reinforcing Materials), the Canadian Highway Bridge Design Code (CHBDC), and the American Concrete Institute (ACI) Committee 440 recommendations are outlined. Methods discussed are: structural analysis; determination of design values; examination of flexural and shear capacity; precautions to ensure ductility or deformability; and calculations of deformation and development length. Similarly, design codes developed for strengthening of concrete structures with FRP, namely the recommendations by the JSCE, ACI Committee 440, and the fib code are compared and discussed with respect to the ways in which FRP may contribute to improvement of the performance of structures in flexure, shear and ductility. Test methods for different material properties of FRP and the bond of FRP to concrete are also presented, with reference to the JSCE recommendations.
