“…In many situations, such as for extended geometries along the y direction, this will suffice to obtain a realistic behaviour of the underground structure. Consequently, in [13], a mobility approach has been proposed in order to join separate computations of the ground and foundations (source mobility) carried out in 2.5D and the 3D computations of the superstructure by means of classical FEM computations (receiver mobilities). This technique has been applied to several real situations.…”

“…The hidden state variables method [15,16,18,19] is an efficient method devoted to such an identification. Among all the degrees of freedom associated with the identified mass, damping and stiffness matrices, those that do not belong to interface Γ are called hidden variables.…”

“…Despite numerous advantages, some numerical difficulties occur with an extensive use of the hidden state variables method: the stability and the numerical cost. In [22] and [19], the stability issue has been addressed. The numerical cost increases with the dimension of the problem (number of degrees of freedom of the interface).…”
