B modeling
==============


Characteristics of modeling
-----------------------------------

B modeling uses the equivalent linear model implemented under *Code_Aster* in Macro-command DEFI_SOL_EQUI [:ref:`U4.90.21 <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.


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).
