94-02: Development of FRP Structural Frame For Industrial Cooling Tower

Three companies have cooperatively developed a structural frame system for industrial cooling towers using pultruded FRP (Fiber Reinforced Plastics) profiles as a substitute for lumber to improve the durability. The mechanical, weather proof and endurance properties in water environment of pultruded materials, and the buckling and joint strength of pultruded tubes were evaluated. A full-scale model of the structural frame was constructed and tested under static and dynamic loads. Design and construction methods for a reliable structural frame system with pultruded FRP profiles have been established. The first industrial cooling tower with a FRP structural frame has operated satisfactorily for more than four years. The number of industrial cooling tower with FRP structural frame is increasing every year.
