The buildings structure is composed by two distinctive structural concepts. The first concept is associated to the periphery of the building and the second is relative to the centre and interior exposition areas.
The structural solution for the periphery of the building, is composed of a ramp in order to access the different floors, is a concrete structure composed by the exterior walls of the building and interior walls that form a U shape, slightly oblique to the façade of the building. These walls support a reinforced concrete slab that spans between both.
The concrete walls support not only vertical loads such as dead or live loads but also must resist wind and seismic actions. For the interior areas of the building (30x22m2) the structural solution is based upon a composite reinforced concrete slab and I section steel beams spanning 22m between interior walls with no additional columns in between.
Connected to the buildings third floor and leading to the outside is a passage in reinforced concrete 6m high over the fault. Construction joints will be provided in order to control the temperature and shrinkage actions.
