GIF++ Design(Structural considerations)
28-Nov-2012
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)
