Modeling A
==============


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.


Characteristics of the mesh
----------------------------

The mesh contains 3079 stitches and 2617 knots (including the sole). The mesh is that of the.

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.

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


.. csv-table::

    "**Combination**
    **(CMB)**", "**Coefficient** **result** **1**
    **(** G **)**", "**Coefficient** **result** **2**
    **(** E **)**) **"
    "ELU_F ", "1,35", "0"
    "ELU_A ", "1", "1"


Since the result 2 has 24 permutations, 25 combinations will therefore be calculated by the command POST_COMBINAISON.


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.

Combinations are defined in the ssls12a.39 file

    "**Combination**

    **(** E **)**) **"
    "ELU_F ", "1,35", "0"
    "ELU_A ", "1", "1"


Since the result 2 has 24 permutations, 25 combinations will therefore be calculated by the command POST_COMBINAISON.


Combination CQCS and weight on POU_D_E 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 POU_D_E elements only.

As an output, a multiple 'RESULTAT' object [mult_elas] will also be retrieved, with 25 combinations.

    "ELU_F ", "1,35", "0"
    "ELU_A ", "1", "1"


Since the result 2 has 24 permutations, 25 combinations will therefore be calculated by the command POST_COMBINAISON.
