Three-dimensional analysis of two-pile caps

this paper compares the results between a non-linear three-dimensional numerical analysis of pile caps with two piles and the experimental study conducted by delalibera. it is verified the load-carrying capacity, the crack pattern distribution, the principal stress in concrete and steel, the deflection and the fracture of the pile cap. the numerical analysis is executed with the finite-element software atena 3d, considering a perfect bond between concrete and steel. the numerical and experimental results are presented and have demonstrated a good approximation, reasserting the results of the experimental model and corroborating the theory.
