| Sumario: | The structural design of pile caps involves determining an accurate internal stress flow system which leads to suitable member dimensioning and steel reinforcement. However, It has been found out that finite element analyses (FEA) derived from the Euler-Bernoulli beam theory fail to adequately describe internal forces in pile caps where the linear theory of elasticity is not fulfilled. This investigation aims to assess diverse arrangements of pile cap strut and tie models (STM) for different geometries and numbers of piles subjected to small and large eccentricities. Subsequently, STM and FEA are compared in order to determine their approaches and limitations oriented to the design of bridge pile caps. |
