Section classification given applies to members subject to bending about the x-x axis only.
Loads given are the total Ultimate factored uniformaly distributed load supported over a beam span L assuming full lateral restra
the compression flange. Self weight of the section has not been allowed for.
UDL values in bold type are governed by the shear capacity.
The unfactored imposed load is assumed to be 40% of the ultimate load given. Unless otherwise indicated, it is only necessary
perform deflection checks if the ratio of unfactored imposed load to dead load is greater than 1.556.
UDL values to the right of the zigzag line in italic type may be susceptible to serviceability deflections > L/360 and so should be
checked under imposed loading. (This deflection limit is for beams which carry a brittle finish.)
Shaded UDL values may be susceptible to serviceability deflections > L/200 and so should be checked under imposed loading.
(This deflection limit is for beams which do not carry a brittle finish.)

Web bearing capacity, Pw = C1 + b1 C2
Web buckling resistance, Px = K (C4 Pw)0.5
For Continuous over bearing: K = 1.0
For End bearing: K = Min. { (ae / 1.4d) + 0.5 , 1.0 }
Where b1 is the stiff bearing length and ae is the distance from the load or reaction to the nearer end of the member.

on classification given applies to members subject to bending about the x-x axis only.
s given are the total Ultimate factored uniformaly distributed load supported over a beam span L assuming full lateral restraint to
compression flange. Self weight of the section has not been allowed for.
values in bold type are governed by the shear capacity.
unfactored imposed load is assumed to be 40% of the ultimate load given. Unless otherwise indicated, it is only necessary to
orm deflection checks if the ratio of unfactored imposed load to dead load is greater than 1.556.
values to the right of the zigzag line in italic type may be susceptible to serviceability deflections > L/360 and so should be
cked under imposed loading. (This deflection limit is for beams which carry a brittle finish.)
ded UDL values may be susceptible to serviceability deflections > L/200 and so should be checked under imposed loading.
s deflection limit is for beams which do not carry a brittle finish.)

F = Factored axial load.
$ For these values of F/Pz the section would be overloaded due to F alone even when M is zero, because F would exceed the
local buckling resistance of the section.
- Not applicable for semi-compact and slender sections.
The values in this table are conservative for tension as the more onerous compression section classification limits have been us

* The section can become slender under axial compression only. Under combined axial compression and bending the section becomes
slender when the semi-compact F/Pz limit is exceeded.
Under combined axial compression and bending the capacities are only valid up to the given F/Pz limit. For higher values F/Pz the
section would be overloaded due to F alone even when M is zero, because F would exceed the local buckling resistance of the section.
Mb is obtained using an equivalent slenderness = u.v.LE/ry.bw0.5
Mbs is obtained using an equivalent slenderness = 0.5 L/ry. Effective length LE = L.

Values in bold are less than the single shear capacity of the bolt.
Values in italic are greater than the double shear capacity of the bolt.
Bearing values assume standard clearance holes.
If oversize or short slotted holes are used, bearing values should be multiplied by 0.7.
If long slotted or kidney shaped holes are used, bearing values should be multiplied by 0.5.
If appropriate, shear capacity must be reduced for large packings, large grip lengths and long joints.
