Use of Fiber-Reinforced Polymer (FRP) Bars in Seismic Design of Building Structures (NDOT 280-24-803)

Fiber reinforced polymer (FRP) has emerged as an alternative for producing reinforcing bars (rebars) for reinforced-concrete (RC) structures. FRP rebars are noncorrosive and provide a suitable solution for construction of RC structures in highly corrosive environments, e.g., salt storage structures as envisioned by the Nevada Department of Transportation (NDOT). Since mechanical behavior of FRP is different from steel, unique procedures for the analysis, design, and construction of RC structures with FRP rebars are necessary. Design and construction guidelines for FRP-reinforced concrete (FRP-RC) structures have been established in other countries. In the U.S., ACI 440 provides general information and guidelines for the design and construction of structural concrete members reinforced with FRP bars, based on the worldwide state-of-knowledge. This guide, however, is limited to non-seismic applications. It, therefore, eliminates FRP-RC applications in most of the western U.S., including most of Nevada, due to the high seismicity of the region. There is a need to advance research and to provide engineering guidelines that will enable application of FRP rebars in seismic design of RC structures. The objective of this study is to develop new design approaches which can be used for the employment of FRP bar in structures which are designed to sustain seismic loading.
