Seismic assessment and retrofitting of a building with base isolation

Hexagone building (Haïti)

Seismic assessment of the Hexagone building following the January 2010 earthquake in Haïti, desgin of the seismic base isolation

Modeling of the building in its current conditions. Adjustment of the numerical parameters based on in situ measures of the eigen modes.
Design of the base isolation based on spectral analysis.
Validation calculations based on time history analysis, with the use of time history accelerations.
Check of the resistance of the base isolation according to normative criteria.
