METERIAL

The structural components referred to in this handbook are of steel to BS 4360, ‘Weldable
structural steels’ and/or its related equivalents.

SECTIONS

The universal beams and columns and tees cut therefrom, the joists, channels, universal
bearing piles and rolled tees are generally as listed in BS 4: Part 1: 1980. Some other joists,
universal bearing piles and rolled tees in regular production are also included.

N.B. The universal beams listed in pages 48 and 49 all have 2º 52’ tapered flanges.

Column core. This section, although listed separately, is rolled in the serial size 356 mm x 406 mm.
It is the most appropriate one to be used as the core of a built-up stanchion if a heavier section
than those rolled is required.

DIMENSIONAL UNITS The dimensions of sections are given in millimetres (mm) and the calculated properties
OTHER UNITS (centroidal distances, cross-sectional areas, radii of gyration, moments of inertia, elastic and
plastic moduli) are given in centimetre (cm) units. Surface areas are in square metres (m2). For
tolerances on dimensions and shape, reference should be made to BS 4848: Part 2.

The units of force, mass and acceleration are those of the Systeme International (SI). They are the
Newton (N), the kilogramme (kg) and the metre per second per second (m/s2) so that 1N -1kgx 1m/s2.
The acceleration due to gravity varies slightly from place to place and for convenience a
‘standard’ value of 9.80665 m/s2 has become generally accepted in structural engineering. With
this convention, the force exerted by a mass of 1kg under the action of gravity is the ‘technical
unit’of 9.80665N. In the same way 9.80665 kilonewtons (kN) is the force exerted by a mass of
1 tonne (1000 kg) under gravity, and 1kN the force from a mass of 0.102 tonne.

WORKING STRESSES

The values given in the safe load tables are based on the allowable stresses in BS 449 as follows:

Thickness of material Grade Allowable stresses (N/mm2)
(mm) of steel

Bending Shear*1 Bearing

Up to and including 40 43 165 100 190
Over 40
Up to and including 65 150 90

55 280 170 320

260 160

Note: *1 On unstiffened web.

*2 Y = yield stress, to be agreed with the manufacturer and not to exceed 350N/mm2.
8
This applies only to universal column sections and plated compound sections and, in
this handbook, affects certain universal column stanchions only for which a value of
Y8 = 325N/mm2 has been assumed.

Web buckling

The buckling values for the unstiffened webs have been calculated in accordance with the formula
in Clause 28a(i) of BS 449, namely W=p tB where

c

W = allowable reaction or concentrated load in N, but tabulated in kN.
p = allowable axial stress for struts as given in BS 449, Clause 30a for a slenderness

c

ratio of (d 3)/t, in which
d = clear depth of web between root fillets
t = web thickness
B = ½D+t +L for end bearings of simply supported beams

pb

= D+2t +L for intermediate bearings, in which
pb

D = overall depth of beam
t = thickness of bearing and/or flange plate

p

L = length of stiff portion of bearing which shall not be taken as greater than half depth
b
of beam for simply supported beams and the full depth of beam for an intermediate
bearing over which the beam is continuous, unless the web is stiffened.

Web crushing

To prevent local crushing of the web, the direction bearing stress at the root of the web is limited to
the values given in BS 449, and included in the table above.

The length of web resisting crushing is determined on the assumption that the load is dispersed
through the flange and the bearing and/or flange plate at an angle of 30º (BS 449, Clause 27e).

COMBINED STRESSES

Where bending and shear stresses, or bearing, bending and shear stresses, are co-existent, the beam
should be checked in accordance with BS 449, Clauses 14.c and d.

DEFLECTION COEFFICIENTS

Clause 15 to BS 449 includes the requirement that the maximum deflection due to loads other than

the weight of the structural floors or roof, steelwork and casing, if any, shall not exceed 1/360th of

the span. For a simply supported beam, the uniformly distributed load WD in kN to produce this
deflection is:

W = 384E=I Cl
D 5x360L2 1000

where C = deflection coefficient tabulated for span L in m
E= modulus of elasticity = 21000kN/cm2 (=210000N/mm2)
I= moment of inertia of beam, in cm4

The load W will be less than the tabular load if the span exceeds 12.17, 16.97 or 10.00 times the
D

beam depth for grades 50, 43 or 55 steel respectively. For such cases, it may be necessary to confirm

that the total load is within the capacity of the beam and that the loads to be considered for

deflection purposes do not exceed WD.

The table below gives limiting values of the span/depth ratio for uniformly loaded simply supported

beams for different grades of steel for various ratios of W /W where W = load considered for
dt d

deflection purposes and W = total load on beam. If the appropriate span/ depth ratio is exceeded,t

then the relevant deflection will exceed 1 /360th of the span unless the bending stress is reduced.

SAFE LOADS (for as-rolled sections)

These are the safe uniformly distributed loads (including self weight) which can be carried by simply
supported beams with adequate lateral restraint to the compression flange. They have therefore
generally been calculated in accordance with the allowable bending stresses given in BS 449.

The loads are printed in three different type faces to draw attention to particular criteria which may
affect the load-carrying capacity of a beam. Bold, italic and ordinary type faces have been used in
that sequence for maximum clarity and the significance of each is explained below.

Bold face. Loads printed in this type are greater than the web buckling capacity of the beam
(UB, joist or channel) alone. If sufficient additional capacity is not provided by the bearing, web
stiffeners will be necessary to realise the full web capacity.

Italic face. Loads printed in this type are within the buckling capacity of the unstiffened web and
produce a maximum deflection of less than 1/360th of the span.

Ordinary face. Loads printed in this type produce a maximum deflection exceeding 1/360th of the
span. Such cases should therefore be examined as indicated above under ‘Deflection coefficients’.

In addition to the criteria covered by the use of different type faces, two other matters require
comment.

(a) Shear capacity. Where the shear capacity of the unstiffened web is less than the bending
capacity of a beam, the safe load is calculated on the allowable average shear stress given
in BS 449.

(b) Web crushing. Many of the loads tabulated, in the various type faces, exceed the beam
component of the direct bearing capacity of the web at its junction with the flange. The
designer should therefore ensure that the length of stiff bearing and thickness of flange plate or
packing (if any) provide a sufficient additional length of web in bearing.

BEAMS WITHOUT LATERAL SUPPORT

The allowable compressive stress due to bending about the x-x axis for universal beams and
columns, joists and channels is the lesser of the values of p given in Tables 2 and 3 a, b or c

bc

(depending on the grade of steel) in BS 449. The values in Table 2 apply when the compression
flange is so supported that lateral instability is obviated. When the compression flange is
unsupported or insufficiently supported laterally, the appropriate Table 3 applies. The maximum
effective length of compression flange which may be used without reduction of the allowable
bending stresses in Table 2 is given as L with the safe load tables.

c

Example: Find the allowable stress, pbc, and the safe uniformly distributed load, W, for a 533 = 210
UB 82 in grade 43 steel spanning 7m without lateral restraint and having the ends of the
compression flange partially restrained.

Effective length = 0.85 x 700 = 595 cm (see BS 449, Clause 26)

l/ry595/4.38 = 136; D/T = 40.

From BS 449, Table 3a, p = 119N/mm2
bc

The safe uniformly distributed load, W = 8fZ/L
= (8 x 119 x 1798 x 103/7000)N
= 245kN

Lateral instability is not a criterion for these sections when bent about the y-y axis and the allowable
stresses in Table 2 apply.

The loads listed are based on a bending stress of 165 N/mm2 and assume adequate lateral support. Without such support the span must
not exceed L unless the compressive stress is reduced in accordance with clause 19a of BS 449.
