This paper was first published in GE’s October 1978 issue and is based on a lecture given by the author at last year’s TRRL/Heriot-Watt University symposium on reinforced earth.
Fibreglass Reinforced Plastics (FRP) based on chemically resistant thermosetting resins and unidirectionally aligned glass flbres appear to have a useful combination of high strength and good corrosion properties which suit the material for use as reinforcement in soil structures.
This paper outlines some properties of FRP straps including their frictional, strength, and corrosion behaviour and in particular the work carried out to establish their long-term durability. Additionally the strain distributions measured along FRP straps in an experimental reinforced earth structure are presented.
