The case-study illustrated makes use of a simplified model for the dynamic analysis of diaphragm walls subjected to seismic excitation, based on the well-known one-dimensional Winkler approximation and on the non-linear shear-beam model for the ground layers on both sides of the wall [Franchin et al 2007]. The model, which can include anchor-ties and account for non- linearity in all of its elements (retained soil, anchors and wall), is applied to the analysis of an idealised non-seismically designed existing bridge abutment. The results highlight the versatility of the model in assessing the system response in its existing state and in progressive states of upgrading, in terms of both wall forces and dynamic displacements.

Abstract
The case-study illustrated makes use of a simplified model for the dynamic analysis of diaphragm walls subjected to seismic excitation, based on the well-known one-dimensional Winkler approximation and on the non-linear shear-beam model for the ground layers on both sides of the wall [Franchin et al 2007]. The model, which can include anchor-ties and account for non- linearity in all of its elements (retained soil, anchors and wall), is applied to the analysis of an idealised non-seismically designed existing bridge abutment. The results highlight the versatility of the model in assessing the system response in its existing state and in progressive states of upgrading, in terms of both wall forces and dynamic displacements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
