Sharing of Lateral Loads and Moments in Pile Foundations
Maurizio Lenzi, Andrea Gambi, Giancarlo Olivucci
In the paper a criterion for the evaluation of the sharing of the lateral loads in a piled foundation is presented. It relies on the compatibility between the rotation of the rigid pile cap and the rotations of the pile heads, following in that the criterion suggested by the Eurocode 8 – Part 5. This assumption leads to an analytical solution which allows to deal with sharing of the lateral loads and moments by means of two main interaction parameters only. A sharing domain is also derived and it shows the role played by the eccentricity of the lateral load on the values of the axial forces and of the bending moments at the head of the piles.
