The radial type spillway gates at Tennessee Valley Authority`s Hiwassee Dam have a history of binding problems caused by growth of the concrete piers and non overflow sections. The concrete growth has resulted in distortion of the embedded side seal channels. The two end piers have been subjected to the largest amount of concrete growth, reducing the width of the two end gate bays permanently by about 3 to 4 inches total. The sides of the gates have had to be shaved several times so that the gates could be operated without binding. Further shaving is not possible without compromising the structural integrity of the gates. The proposed modification described in this paper would eliminate the need for further shaving and would accommodate several inches of future growth. The proposed modification could also serve as a guide for future design of radial gates where concrete growth problem is expected.
