Numerical analyses of two-pile caps considering lateral friction between the piles and soil

abstract: Pile caps are structural elements used to transfer loads from the superstructure a group of piles. The design is normally based on analytical formulations, considering strut and tie method. Through advance computational technology, use an integrated soil foundation model may suggest behavioral trend obtain more realistic modeling for element being studied. This work aimed at analyzing, in numerical fashion, behavior reinforced concrete two-pile lateral friction between piles ground through continuous modeling, as well analyze portion load that transferred directly by cap. was modeled node coupling contact elements. Simulations were performed three types (sandy, clayish, soilless), cap heights, pile lengths. Soil parameters obtained semi-empirical correlations. these analyses, conclusion reached that, average, 4.50% force applied pillar In terms principal compression stresses, superior nodal region, tends form beyond section column. Alternatively, increasing stiffness provided, increase carrying capacity models.
