ANALYSIS OF SOIL-STRACTURE INTERACTION ON BRIDGES’S FOUNDATIONS
Bridges. Reinforced Concrete. Soil-structure interaction
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 will 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 will realize approach to ISE analytical models with a focus to Matlock and Reese solution, the results will compared with those obtained by three-dimensional numerical modeling in terms of displacements and solicitants efforts. We hope that the results will 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.
