IS 456 CODE COMPLIANTSpecs
STRUCTURAL THEORY

THE RATIO OF STIFFNESS.

Total thickness is determined by Serviceability Limit States, specifically deflection. IS 456 provides basic span-to-depth ratios to ensure that slabs don't sag excessively under long-term loads, which could cause cracks in partition walls or discomfort to occupants.

Common Questions

1
What is the span-to-depth ratio for a simply supported slab?

For spans up to 10m, the basic span/depth ratio is 20 for simply supported slabs as per IS 456 Clause 23.2.1.

2
Does reinforcement affect slab thickness?

Yes, the percentage of tension reinforcement (pt) and the stress (fs) are used to calculate the modification factor which can reduce or increase the required depth.
