Evaluation of Deflection and Bending Strength Characteristics of Fiber-ReinforcedPlastic Lighting Standards

摘要

The results of tests performed on six different models of fiberglass-reinforcedplastic (FRP) lighting standards are presented. Four parameters, including deflection of the pole tip under a specified bending load, ultimate bend strength, degradation of coating after 2,500 hours of accelerated weathering, and coating thickness, were evaluated. Results are compared to requirements in the California Department of Transportation 1992 Standard Special Provision 86.08.5 'Fiberglass Lighting Standards' Three different styles of FRP poles, some with breakaway anchor bases, direct burial breakaway joints, and non-breakaway anchor bases, (each style in lengths of 9,140. mm and 10,700 mm), were obtained from two manufacturers of FRP lighting standards.
