Abstract
Tainter Gates for Spillways - The radial or tainter gate is the most common type of spillway crest gate used on dams. The Corps has constructed 800 in the last 15 years. Tainter gate advantages are simplicity, light weight, low hoist requirements, favorable hydraulics, and service and maintenance ease. Structural components for tainter gates are: skin plate assembly, end frames, trunnions, and anchorages. These are arc-welded from high strength, low alloy steel for the skin plate assembly and horizontal girders and structural carbon steel (A36) for the end frames. Working stresses for tainter gate design should conform to EM 1110-1-2101. The basic allowable stress is 50% of the yield point of the steel being used. Gate dimensions are controlled by practical considerations, resulting in many 40- to 50-ft-wide tainter gates for flood control projects. Since the 1950's, prestressed concrete trunnion girders have been widely used, making these large gates practical. Several satisfactory programs for tainter gate design are available, but there is much duplication. These programs should be reviewed and tainter gate programs recommended for Corps-wide use. There are no programs available for designing prestressed concrete trunnion girders and anchorage systems; design programs should be developed for these items.
