BLOCKS (STABILITY)

Stable + Stable ++Stable

• Stability for seismic load case• Stable equilibrium in the configuration of blocs• Contribution of vertical load to the stability

BLOCKS (LOAD ON THE FLOOR)

• 5.6 m maximum height• 1.0 m height over the blocks• Metallic structure over the blocks• Possible added load on the top

• Max ground tension under the blocs: 0.1-0.2 N/mm2 (OK)

COVERING STRUCTURE(GEOMETRY)

• Length: 4.8 m• Inter-axe: 2.4 m• Metallic beams: VKT 200 • Overlap in the support of 40 cm each side• 1 level of 0.8 m height of concrete over the structure

COVERING STRUCTURE(VERIFICATION)

• Steel beams:• Flexion – smax = 76.0 N/mm2 (<235 N/mm2)

• Shear – tmax= 2.1 N/mm2 (<144 N/mm2)

• Deformation – dmax= 8.7 mm (<L/400)

• Concrete beam (efforts for dimensioning):• Flexion – Mmax = 867.0 KN.m

• Shear – Vmax= 638.0 KN

COVERING STRUCTURE(FIXATION)

• Ponctual fixation to the blocs of each group of beams

RAISED FLOOR(20 MM STEEL PLATE)

• Standard structure (estimated):• Supports HEA-120• Beams HEA-140 (support of plates)• Max weight = 8 Tons in 4 points(base plate, support, beam and plate)

RAISED FLOOR(150 MM STEEL PLATE)

• Adapted structure (estimated):• Supports HEA-140• Bracing between supports• Without structural beams• Max weight = 8 Tons in 4 points(base plate, support, beam and plate)
