2. Modeling A#
2.1. Characteristics of modeling#
The reinforced concrete walls, floors and footing are modelled by DKT plate elements. Reinforced concrete is modelled with a simple elastic law. Beams and columns are modeled by POU_D_E elements. These are considered elastic.
2.2. Characteristics of the mesh#
The mesh contains 3079 stitches and 2617 knots (including the sole). The mesh is that of the.

2.2.1. Signed Full Quadratic Combination (CQCS)#
The command takes directly as arguments the “RESULTAT” objects corresponding to the CQCS loads to be combined. These fields are calculated using fields CQC from the COMB_SISM_MODAL command. This result is calculated over the whole structure.
As an output, a multiple “RESULTAT” object [mult_elas] will also be retrieved, with 24 combinations.
The combinations are defined in the ssls14a.38 file. These are Newmark combinations, namely 24 permutations of the type±Ex±0.4EY±0.4EZ.

2.2.2. Combination CQCS and weight all over the structure#
The command takes directly as arguments the “RESULTAT” objects corresponding to the two loads to be combined [from commands MECA_STATIQUE and COMB_SISM_MODAL]. This result is calculated over the whole structure.
On output, a multiple “RESULTAT” object [mult_elas] will also be retrieved, with 25 combinations.
Combinations are defined in the ssls12a.39 file

Since the result 2 has 24 permutations, 25 combinations will therefore be calculated by the command POST_COMBINAISON.
2.2.3. Combination CQCS and weight on DKT elements#
The command takes directly as arguments the “RESULTAT” objects corresponding to the two loads to be combined [from commands MECA_STATIQUE and COMB_SISM_MODAL]. This result is calculated on DKT elements only.
As an output, a multiple “RESULTAT” object [mult_elas] will also be retrieved, with 25 combinations.
