TP24-07 A Comparison of the New LRFD Design Standard for FRP and Current ASD Practices Repair and Construction

TP24-07 A Comparison of the New LRFD Design Standard for FRP and Current ASD Practices Repair and ConstructionField erected stick built cooling towers until the early 1980s, were principally constructed of pressure treated wood products. Until the 1980s the lumber of choice had been old growth Redwood. Due to certain environmental concerns though, old growth Redwood became difficult to obtain and Douglas Fir became the common choice of material. It was also at that time that Pultruded Fiberglass (FRP) started to make inroads into the cooling tower market. As
