Steel design to IS 800:2007 (LSM).

For projects to Indian standards, Volex Anvil designs steel beams to IS 800:2007 by the Limit State Method: the design bending strength Md including lateral-torsional buckling, the design shear strength Vd, and the serviceability deflection, each referenced to its IS 800 clause.

The section properties and material factors follow IS 800:2007, so the Md and Vd match Indian textbook and SP 6 steel-table results.

Frequently asked

Which method — WSM or LSM?
The Limit State Method of IS 800:2007, the current basis for Indian steel design.
Does it do lateral-torsional buckling?
Yes — the bending strength Md includes the LTB reduction (βb and the bending-stress curve) of IS 800 §8.2.2.
Is it validated?
The bending and shear strengths are checked against IS 800:2007 — within 0.00%.
Free tier?
Yes — 10 calculations a month free; Pro (£29/month) adds unlimited runs and PDF calc sheets.
