Material properties
-----------------------

Isotropic linear elastic material: :math:`E=2.1E+11\mathrm{Pa}`

Coefficient of linear expansion: :math:`\alpha =1.E–05°{C}^{-1}`


Boundary conditions and loads
-------------------------------------

Articulation in :math:`A` (:math:`{u}_{A}={v}_{A}=0`).

Roller support in :math:`B` and :math:`C` (:math:`{v}_{B}=v{’}_{C}=0`).


Initial conditions
--------------------

Cumulation of 3 requests:

• support displacement: :math:`{v}_{A}=–0.02m`, :math:`{v}_{B}=–0.03m`, :math:`v{\text{'}}_{C}=–0.015m`

• point forces: :math:`{F}_{E}=–\mathrm{150 }\mathrm{kN}`, :math:`{F}_{F}=–\mathrm{100 }\mathrm{kN}`

• expansion effect of all the bars for a temperature difference of :math:`30°C` compared to the assembly temperature (reference geometry).
