ANÁLISE ESTRUTURAL DE UM DISPOSITIVO DE CALAGEM PARA A COMPORTA ENSECADEIRA DA BARRAGEM OITICICA EM JUCURUTU/RN

. Stoplogs are robust equipment normally used in sewage treatment plants, irrigation and hydroelectric power plants, with the aim of containing the flow of water in the upstream-downstream direction. However, when the passage of water is allowed, storage control of this equipment is not always planned out. The objective of this work is to carry out a structural analysis of the suspension device of the supplementary water intake of the Oiticica dam in Jucurutu/RN, used to support and maintain the lower panel of the stoplog during use and opening of the water intake, given the need for storage. For this, a U-beam with a 4”x1.5/8”x3/16” profile was considered, with bending stress calculations being performed for a beam supported on both ends, and a structural static simulation was carried out, considering the movement made by the electric hoist. The results of these calculations attested that the suggested beam is sufficient to safely keep the lower panel of the stoplog suspended.
