| Résumé : | Under cyclic loading, vulnerable soil structures are prone to experience liquefaction. Actually, their typical contractive behaviour can lead, under a deviatoric loading and constant volume condition, to a pore pressure build up which may cause an important or total loss of the shear resistance. BRO model, which is able to model this phenomenon, differs from the other soil models devoted to seismic computation by a simple identification procedure for the model parameters. It makes it convenient for the use of engineers. BRO model used to present a lack of robustness, it has been improved and then tested on San Fernando dam during the same-named seismic event in 1971. |
