Expertise of damage in a reinforced concrete structure
Subject : Swimming pool of the Chalet “Black Pearl” – Courchevel 1850
Sixense performed non-linear calculations to define the origin of the disorders.
At the same time, our design office carried out standard linear calculations to establish the margin maps and evaluate the deficiencies. Subsequently, our office made a proposal for a reinforcement solution and looping calculation.
The chalet “Black Pearl” was built in 2009 in Courchevel 1850. It has several levels, including one with a swimming pool. The pool is made up of a reinforced concrete frame resting on posts and walls visible in the chalet’s garage. The structure of the swimming pool has suffered from cracks in the underside of the pool, on the sides of the pool walls and from water leaks.
La prestation de Sixense necs :
- Study the real behaviour of the structure through 3D numerical modelling and non-linear analysis, taking into account the cracking of the concrete and the plasticization of the reinforcements. This is done in order to calculate the real stresses in the different elements and to compare them with the in situ observations. This step allows to conclude on the origin of the disorders.
- Carry out standard calculations by analysing the linear elastic behaviour of the materials for ELS and ELU combinations in order to evaluate the structural deficiencies in reinforcement and squaring.
- Propose reinforcement solutions and carry out a rebar calculation.
