Deformações nas diagonais comprimidas em blocos sobre duas estacas

Abstract: Existem vários modelos para o dimensionamento de blocos sobre estacas, sendo que um deles é o modelo de escoras (bielas) e tirantes. Escoras são representações gráficas dos fluxos das tensões principais de compressão de um dado elemento, enquanto que os tirantes representam os fluxos das tensões principais de tração deste. A NBR 6118:2003 [1] recomenda a utilização de modelos de escoras e tirantes para o dimensionamento e verificação de elementos estruturais de volume, idéia que se aplica aos blocos sobre esta… Show more

“…The french researchers consider that the beginning of the strut, next to the upper nodal zone, occurs at ¼ of the column size in the considered direction, measured from the column face. The collected data for the analysis was extracted from the works of Adebar et al [4], Mautoni [5], Fusco [6], Chan and Poh [7], Miguel [8], Delalibera and Giongo [9], Barros [10], Munhoz [11], Mesquita [12] and Cao and Bloodworth [13] and are shown in Tables [1] to [10]. It is also important to clarify that the experimental tests of Blévot and Frémy [2] were not considered in this work due to the large number of tests.…”

“…To calculate such forces, the equilibrium of the nodal region was made as it is shown in Figure [ 2]. The presence of a bending moment at the base of the column was studied by Delalibera and Giongo [9].…”

“…Later studies (Suzuki et al [5][6][7][8], Bloodworth et al [9], Gonsalves et. al [10], Delalibera and Giongo [11], Gu et al [12]) experimentally analysed the influence of different design variables on pile cap behaviour. As some studies described brittle fracture due to punching shear, some authors (Adebar and Zhou [13] and (recently) Guo [14]) proposed methods based on checking the stresses in the bearing areas to limit the resistance of the pile caps due to this type of failure, while, Miguel-Tórtola et al [15] recommended limiting punching stresses to avoid this problem on the basis of their own experimental studies on pile caps with three piles and a centered load.…”
