Footnote 6

For uniformly loaded simple span beams, the deflection shall be calculated as follows:

$D = \frac{156.25 w L^{4} \times 10^{6}}{E b d^{3}} ⊥ \frac{2400 w L}{E b d}$

where:

D = deflection (mm)

w = specified uniform load (N/m) L = span (m)

E = modulus of elasticity (shear-free) (MPa) b = beam width (mm)

d = beam depth (mm)

Footnote 7

Tension values are adjusted to a specified length of 6 096 mm (20'). For longer lengths, the tension values shall be adjusted by (6 096/L)^(0.146), where L is in mm.
