Nonlinear thermal
Analysis of the effects of a fire
- Studied structure: a complete <<office>> building floor
- Mechanical behaviour: damage mechanics
- Thermal behaviour: Nonlinear time history (property of a material), conductivity, radiation, convection of heated gas
- Load: normal load modified according to the combustion energy available (fuel)
Objectives : Estimate the propagation of heat in the structure elements following a fire in one of the rooms. To evaluate the degree of damage in the reinforced concrete basemat.

Thermal non linear
Steel-concrete composite beam exposed to fire
- Studied structure: steel-concrete composite beam with its compression slab
- Thermal behaviour: heat capacity, thermal conductivity and density depending on the temperature
- Boundary conditions: thermal transfer by convection and radiation (exchange coefficient according to temperature)
- Load: fire type (ISO 834) applied (ambient condition and applied radiation)
Objectives : To obtain a map of the temperature inside the structure composed of two materials, according to the duration of exposure in the fire.
