Design of GFRP Slip Liner for Retrofitting Corroded Metal Culverts
Corrosion of corrugated metal pipes (CMP) is a significant problem facing all U.S. Departments of Transportations. There is an urgent need to provide an efficient solution, that is corrosion-resistant, to retrofit thousands of corroded CMP across the country. High specific strength, high strength-to-weight ratio, and corrosion resistance made fiber-reinforced polymers (FRP) the engineer’s choice material where corrosion is a problem. This paper discusses the design method for using glass fiber-reinforced polymer (GFRP) slip liner to retrofit CMP culvert. The structural aspects, such as wall thrust, buckling, deflection, and bending strains, along with hydraulic design, are considered. The proposed method is used to design a GFRP retrofit slip liner for a 25 ft corroded steel CMP. The retrofitting system is modeled using the finite element method to predict the magnitude and location of maximum stresses under service conditions and ensure the retrofitted culvert's safety under traffic loads.
