Design Summary

Recommended Minimum Thickness: 150 mm

Governed by: Corner Loading

Design Notes:

• Load factor of 1.5 applied to design loads
• Minimum slab thickness typically 125mm for industrial floors
• Consider durability requirements for concrete strength selection
• Edge and corner loadings require higher thickness than interior
• Fatigue considerations reduce allowable stress for high repetition loads
• Back-to-back racks with close spacing (<2×thickness) combine loading effects
• Typical rack spacings: X=2.4-2.7m longitudinal, Y=0.8-1.2m transverse
