Expertise of a building collapse due to fire

Assessment of the resistance of the post tensionned precast slabs

Expertise of the behaviour of a slab exposed to fire with the mean of numerical calculations, estimate of compression failure processes in the slab, assessment of the influence of continuity and support restraints, and of geometrical 2nd order effects.

- Non linear time history thermal analysis, in order to determine the temperature evolution in all locations of the slab, as well as in the support area,
- Non linear mechanical analysis, in order to follow the evolution of the strain state in materials, and to observe the occurence of failure processes.
