Characteristics of pitched beams of I-section (Type 1)

Symbols:

H, h₁, h₂ – height;
B, B₁, b₁ – width;

S – rib thickness;
L – length.

When choosing the form and mark of beam must be guided by the following calculations and dependencies:

1) δ = (H-H₁) / L/2 * 100%

2) 1 150 mm ≤ H-H₁ ≤ 1 314 mm

3) B = 2b₁ + S
