Tassements et pouvoir endommageant d'un mouvement sismique
The design of an index measuring the damaging power of a seismic record is generally undertaken within the frame of Structural Dynamics. Herein, we propose to undertake it within the frame of Soil Dynamics. The global settlement undergone by a soil profile is regarded as an indicator of the damage caused by a seismic motion. The ability of some classical damage index to predict the settlement is analysed. A predictor of expectable settlement is proposed. This predictor, which account for essential features of the soil profile, appears therefore as a new improved damage index.
