4. B modeling

4.1. Characteristics of modeling

B modeling uses the equivalent linear model implemented under Code_Aster in Macro-command DEFI_SOL_EQUI [U4.90.21] with a loading in the free field and a plane wave approach considering a 1D — 3 components hypothesis. Modeling B adopts the boundary conditions and loading defined in the reference problem.

4.2. Tested sizes and results

The results of modeling A are taken for reference at two levels of the soil column, points C (inside layer 2) and D (inside layer 3).
