This paper deals with the resilient condition that may be reached by driven piles, during its installation as well as under static cyclic and monotonic loading tests. During the 1950’s Van Weele observed its effect in the context of a method for the separation of the toe and shaft loads at failure using the results of static cyclic loading tes...
View ArticleForts, including in this designation military castles, present high complexity due to their nature. Methodologies followed in the rehabilitation of forts are briefly presented, with the emphasis on characterization of materials and rock masses and on tests and numerical models developed for ancient forts. Studies concerning forts with Portuguese legacy ...
View ArticleThis article presents the results of a case study carried out in the cemetery of Tabuleiro, state of Minas Gerais, Brazil, from August 2007 to March 2008. Five sampling wells were drilled within the cemetery area, and water samples analyzed for pH, conductivity, nitrogen ammoniacal nitrogen, nitrate, total phosphorus, sodium, potassium, calcium, mangane...
View ArticleFor the design of mortar mixes for filling root piles, the Brazilian standard NBR 6122, establishes a minimum compressive strength of 20 MPa (28 days), minimum cement content of 600 kg/m3 and a water to cement ratio between 0.5 and 0.6 and allows the use of water-reducing admixtures; however, the definition of a minimum cement con...
