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.
Harmfulness expertise of local corrosion in reinforcement bars
Diaphragm-wall quay - London Gateway Port
Finite element modelling and non linear analysis, computation and examination of material stress mappings, assessment of resistance margins of the reinforced concrete diapghram-wall to ultimate limit state, assessment of the effects of steel corrosion on the structure behaviour, conclusion on the harmfulness level of the defects.
Expertise of damage in a reinforced concrete structure
Swimming pool of the "Black Pearl" chalet - Courchevel 1850, France
Non linear calculations in order to specify the origin of the damage, linear calculations to establish reinforcement mappings and estimate the lack of reinforcement, retrofitting solution and final check calculation
