IPE 100 vs HEA 100
- IPE 100 is 51 % lighter than HEA 100 (8.1 vs 16.7 kg/m).
- HEA 100 has 2.0× higher strong-axis stiffness Iy.
- HEA 100 has 8.4× higher weak-axis stiffness Iz, which governs columns and lateral stability.
- HEA 100 has 111 % higher plastic bending resistance (Wpl,y).
- Per kilogram of steel, both are similarly efficient in bending (Iy/G ≈ 21 cm⁴ per kg/m).
