Long-term Dynamic Monitoring of a Concrete Block of the Itaipu Hydroelectric Dam
(2021)
Dams are structures that offer multiple benefits: water for irrigation, energy, flood control,
among others. The structural integrity of these structures can be affected over time by agerelated
deterioration, flooding, ...
Estudo de subpressões em barragens de concreto no contexto da segurança de barragens
(Universidade Tecnológica Federal do ParanáCuritibaBrasilCurso de Engenharia CivilUTFPR, 2018-12-17)
Structures historically very important to the humanity progress, dams are influenced by several loads, which determine their stability and safety conditions. The uplift pressure, load pressure exerted under a structure, ...
Análise estrutural da barragem da central geradora hidrelétrica Alceu Viganó, localizada em Cruzeiro do Iguaçu - PR
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2021-08-16)
Hydroelectric power in Brazil has always been predominant among the other sources of energy generation; moreover, recently the demand for hydroelectric power plants has increased due to their smaller size and lower impact. ...
Corrosion monitoring of post-tensioned strands at the Piedra del Aguila spillway
(Hydropower & Dams, Aqua-Media International Ltd, 2014-12)
The Piedra del Aguila project in Argentina is a concrete gravity dam constructed in the 1980s,on the Limay river. The dam includes a spill way channel controlled by four gates. The spillway structure includes several ...
Uma síntese acerca de estudos de modelos reduzidos de barragens
(Universidade Tecnológica Federal do ParanáPato Branco, 2013-08-14)
This work aims to present a brief review of studies of hydraulic dams and the importance of reduced models. For this, we choose to search the history of dams and existing reduced models. A reduced model, two-dimensional ...
