résumé This paper concerns a numerical study of the influence of soil-footing-structure interaction ground-foundation-structure on the behaviour of frames on soft soils. The study is carried out using a global modeling integrating in the same analysis the soil, the footings and the structure. The global approach is compared to uncoupled approaches, which consist to replace the soil-footing system by equivalent elements. This comparison shows that the performance of the uncoupled methods largely depends on the soil-structure realtive stiffness and on the spacing ratio between the frame’s footings. Recommendations are proposed for the use of uncoupled methods for the analysis of frames on soft soils.
