Fibre composites are used increasingly as guardrail systems to ensure safety from falling from heights due to their high strength, high corrosion resistance and low maintenance. However, there has been limited study conducted to understand the behavior of fibre composites guardrail under the applied loads. In this study, the behavior of glass fibre reinforced polymer (GFRP) guardrail system mounted on top of a steel beam with different joint connectors (polypin, rivets, polypin + epoxy, and rivets +epoxy) is determined. The results of the experimental work showed that the guardrails with joints connected with either polypin or rivets combined with epoxy exhibited higher failure load and stiffness than those connected using polypin or rivets alone. The guardrail failed in the 4-way tee joint at the middle post when the load was applied to post while failure occurred in the 3-way tee joint at the side post when loaded to the member. The results of the study indicate that that the strength and sidesway of GFRP guardrails exceed considerably the minimum requirements for post and rail system of guardrails.
