+ 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)
