Seismic assessment and retrofitting of reinforced concrete industrial structure

Building 59 - CEA Marcoule

Seismic study of the building 59 of CEA Marcoule in the context of the 04/10/2010 Ministerial Order regarding classified industrial plants. Assessment of the existing reinforced concrete structure and retrofitting suggestions.

In the context of the construction of a future classified industrial plant intended for storage of contaminated chemical wastes, the building 59 of CEA Marcoule was assessed to seismic forces according to the 04/10/2010 Ministerial Order.

The study was about the seismic behaviour of the existing reinforced structure, the foundations and the internal masonries.

It followed the below steps :
- Document examination
- On site visite
- 3D finite element modeling
- Modal-spectral analysis
- Assessment of reinforced concrete structural elements, foundations and masonries
- Retrofitting suggestions
- Retrofitting works cost estimate
- Check calculation taking into account the retrofitting solution
- Detailed drafting of the retrofitting solution
