Abstract
A modelling technique of the cross-sections of underground structures based on the combination of modal shapes by response spectra is developed and calibrated according to the vertically propagating shear-wave model. Using the developed technique, the influence of several parameters in the flexibility index (ground-structure relative stiffness) were studied. To point out a few practical implications and simplifications introduced in the model, essentially related to the material behaviour adopted, four cases were studied in detail. To cover the lack of compatibility between the damping of the response spectrum, the ground stiffness and the strain level, more analyses with compatible properties were conducted.
