“…Finally, a particularly advantageous tool for reproducing the response of the elastic half-space is the Boundary Element Method (BEM), because only the boundary of the elastic substrate has to be discretized, see [24] and references cited therein. However, soil tractions are usually considered as nodal reactions in the FE model of the foundation beam and, once again, the rotation continuity between beam and substrate is neglected.…”

“…A particularly advantageous tool for capturing the response of the elastic half-space is the Boundary Element Method (BEM), which allows for meshing only the substrate boundary (Ribeiro and Paiva, 2015). However, soil tractions are typically considered as nodal reactions in the FE model of the foundation beam, so that, also in this case, the continuity of rotations between foundation and substrate is ignored.…”

In the analyses presented, the soil-structure interaction is accounted for by means of a FE-BIE approach, in which the structure is modelled with displacement-based beam finite elements, whereas the boundary between structure and substrate is described in terms of surface tractions by means of a boundary integral equation incorporating a suitable Green's function. This mixed formulation ensures full continuity between structure and substrate in terms of displacements and rotations. To take account of structural nonlinearities, potential plastic hinges are defined at the end sections of the beam elements in the form of semi-rigid connections characterized by a rigidplastic moment-rotation relationship. The incremental analyses carried out emphasize the effectiveness of the model in reproducing collapse mechanisms and stiffness loss of the structure for increasing loads. Moreover, the adopted formulation is able to capture both interfacial shear tractions and vertical normal tractions which develop along the substrate boundary under a variety of loading conditions.
