The structural design of works of art considering the soil-structure interaction (ISE) is an expected reality in standards, but still lacks research regarding the validity of analytical and computational models, especially with regard to horizontal loads on foundations, which is why still lies very empiricism in engineering offices, or simplifications that ignore the ISE. In this respect, the work presents a case study involving the design of foundations on piles of a bridge in reinforced concrete with two straight spars, supported by pillars aligned. Is realized approach to ISE analytical models with a focus to Matlock and Reese solution, the results are compared with those obtained by three-dimensional numerical modeling in terms of displacements and solicitants efforts. The results confirm that the computational methods when calibrated for reliable input parameters, tend to distance themselves less physical reality of the phenomenon that the analytical methods, because they allow to simulate the problem three-dimensionally and taking into account the group effect of piles.
