FRP COMPOSITES FOR LOW-HEAD WATER CONTROL STRUCTURES
|Publication Date:||1 August 2018|
This guide specification covers design-build gates and stop logs or boards made from fiber reinforced polymer (FRP) composite materials for use in low-head water control structures and weirs. Structures covered by this specification are to have a maximum static hydraulic head of 6.1 meters20 feet, accounting for overflow, a maximum height of 3.7 meters12 feet and a maximum width of 3.7 meters12 feet. This guide specification is not applicable if catastrophic failure of the water control structure would create a life safety risk as per ER 1110-2-1156. This specification covers the performance requirements for composite gates and stop logs or boards as well as appurtenant components such as seals, guide frames, anchors and fasteners.
