IS 800

The Indian standard for steel structure design (IS 800:2007, Bureau of Indian Standards).

What it is

IS 800:2007, “General Construction in Steel — Code of Practice”, is India's primary steel design standard; the 2007 revision adopted Limit State Design.

Design method

Limit State Design with material partial safety factors γm0 = 1.10 (yielding/section) and γm1 = 1.25 (rupture/stability).

Key checks

• Tension — gross-section yielding (γm0) and net-section rupture (γm1)
• Compression — buckling curves
• Flexure — section classification (plastic/compact/semi-compact/slender) and LTB, shear
