Chinese Design Recommendations for External Strengthening by FRP Laminates and Related Works in ACI and ISIS Code Provisions

Abstract:

By comparing the Chinese CECS 146:2003, the American ACI 440.2R-02 and the Canadian ISIS Design manual No.4, discussion is extended in terms of ways to improve the performance of concrete structures. Although the Chinese code treats only carbon fibers, the basic concepts for FRP strengthening are common to all three examined design. However, safety factors differ because of the different backgrounds and application experience. The ACI 440.2R-02 goes into great detail concerning FRP materials and utilization where creep and fatigue are important factors. The ISIS manual No.4 gives many design examples and promotes the use of FRP through easy-to-use design charts. The CECS 146:2003 also mentions applications for seismic resistance. Further improvement in the area of design stipulations for use of FRP laminates will include standardization of safety factors, and also promotion of these guides for a wide use around the industry.
