Specifications

The structural sections referred to are produced to the following specifications:

BS4: Part 1: 1993: Structural steel sections - specification for hot rolled sections

Structural hollow sections:

Section properties for all sections available in the UK are given together with those from other standards used in Europe and the rest of the world. Corus supply all of the sections listed subject to the normal terms and conditions. However, sections outside of the standard British range may not be generally available in the UK. The user should therefore satisfy himself as to the available supply before specifying these sections. Corus will be happy to help and can be contacted at the contact addresses in the contact section.

In certain circumstances, Corus may be able to provide sections outside of the standard ranges. Please consult the relevant sales office for further details.

Symbols used are generally the same as those in BS 5950: Part 1:1990, BS4 or appropriate EN standards. In addition the following symbols have been used:

The structural sections referred to are of weldable structural steels to BSEN10025: 1993, BSEN10113: 1993 and

The steel grades covered in the tables are S275 and S355, which are equivalent to design grades 43 and 50 of BS 5950: Part 1. Details of the corresponding grades are given in the Standards section.

EN 10210: Part 2: 1997: Hot finished structural hollow sections of non-alloy and fine gram structural steels. Tolerances, dimensions and section properties

Some other hot finished structural hollow sections currently in regular production are also included. Although not listed in EN 10210-2, these additional sections comply with the tolerances of that standard.

ES 4848: Part 4: 1972: Hot rolled structural steel sections. Equal and unequal angles Including Amendments 1 (February 1974), 2 (October 1982) and 3 (February 1986)

For tolerances on shape, reference should be made to BS EN 10034 for UB, UC and bearing piles. For tolerances of other sections, reference should be made to the above standards. Extracts giving the main tolerance details are given in the design section.

The dimensions of sections are given in millimetres (mm). Mass is given in kg/m. Generally, the centimetre (cm) is used for the calculated properties. For surface areas, the metre (m) is used and for the warping constant (H), the decimetre (dm) is used.

1 dm6 = 1 x 10-6 m6 = 1 x 1012 mm6

Mass per metre has been calculated assuming the density of steel is 7850 kg/m3.

In all cases, including compound sections the tabulated masses are for the steel section alone and no allowance has been made for connecting material or fittings.

The ratios of the flange outstand to thickness (b/T) and the web depth to thickness (d/t) are given for I, H and channels sections. The ratios of the outside diameter to thickness (D/t) are given for circular hollow sections. The ratios d/t and b/t are given for square and rectangular hollow sections. They have been calculated using the dimensions specified in Figure 3 of BS 5950: Part 1 and are for use when element and section class are being checked to the limits given in Table 7 of BS 5950: Part1.

All section properties have been accurately calculated and rounded to four significant figures. They have been calculated from the metric dimensions given in the appropriate standard. For angles, BS4848: Part 4: 1972 assumes that the toe radius equals half the root radius.

Radius of gyration (r)

The radius of gyration is a parameter used in buckling calculation and is derived as follows:

where A is the cross-sectional area

Elastic modulus (Z)

Z =I/y

where y is the distance to the extreme fibre of the section from the elastic neutral axis.

For channels the elastic modulus about the minor (y-y) axis is given at the toe of the section

where:

B is the width of the section

For angles the elastic moduli about both axes are given at the toes of the section

where:

A is the leg length perpendicular to x-x axis

B is the leg length perpendicular to y-y axis

Buckling parameter (u) and torsional index (x)

The buckling parameter and torsional index used in buckling calculations are derived as follows:

The second moment of area of the section, often referred to as moment of inertia, has been calculated taking into account all tapers, radii and fillets of the sections.

r = (I / A)1/2

For castellated and cellular sections, the radius of gyration given is calculated at the net section as required in

The elastic modulus is used to calculate the moment capacity based on the design strength of the section or the stress at the extreme fibre of the section from a known moment. It is derived as follows:

For castellated and cellular sections the elastic moduli given are those at the net section. The elastic moduli of the tee is calculated at the outer face of the flange and toe of the tee formed at the net section.

y = B - Cy

Cy is the distance from the centroid to the outer face of the web

i.e yx = A - Cx and yy = B - Cy

Cx is the distance of the centre of gravity from the back of the angle, referred to the x-x axis and

Cy is the distance of the centre of gravity from the back of the angle, referred to the y-y axis.

These formulae do not apply to joists, which have tapered flanges. Details are given in SCI Publication 057.

u = [(4Sx2g)/(A2h2)]1/4

x = 0.566h[A/J]1/2

u = [(IySx2g)/(A2H)]1/4

x = 1.132[(AH)/(IyJ)]1/2

Sx is the plastic modulus about the major axis

g = [1-Iy/Ix]

Ix is the second moment of area about the major axis

Iy is the second moment of area about the minor axis

h is the distance between shear centres of flanges (for T sections, h is the distance between the shear centre of

The warping constant and torsion constant for I, H and channel sections are calculated using the formulae given in SCI publication (P057) Design of Members Subject to Combined Bending and Torsion. For Tee sections cut from

UB and UC sections, the warping constant (H) and torsion constant (J) have been derived as given below. However, the values of the warping constant (H) for Tee sections are not tabulated as these are normally very small.

Torsion constant (J)

For circular hollow sections

J = 2I

For square and rectangular hollow sections

where:

I is the second moment of area

t is the thickness of section

B is the breadth of section

D is the depth of section

Torsion modulus constant

For circular hollow sections

For square and rectangular hollow sections, the sectional properties have been calculated using the corner radii of 1.5 t externally and 1.0 t internally, except for the following square hollow sections, where an external corner radius of 2.0 t and an internal radius of 1.0 t are used:

J = 1/3 t3h + 2k Ah

h is the mean perimeter = 2 [(B - t) + (D - t)] - 2 Rc (4 - p)

Ah is the area enclosed by mean perimeter = (B - t) (D - t) -Rc2 (4 - p)

k =2 Ah t / h

Rc is the average of internal and external corner radii.

C = 2Z

For square and rectangular hollow sections

C = J / ( t + k / t )

where Z is the elastic modulus and J, t and k are as previously defined.

n = F/(A py), where F is the Factored axial load, A is the gross cross sectional area and py is the design strength of the section.

For lower values of n, the reduced plastic modulus, Sr = K1 - K2.n2, for both major and minor axis bending.

For values of n higher than n2, the reduced plastic modulus, Srx = Srx2 = K3(1-n)(K4+n), for major axis bending.

For values of n between n1 and n2, the reduced plastic modulus, Srx = Srx1 + (Srx2 -Srx1)(n-n1)/(n2-n1), for major axis bending.For lower values of n, the reduced plastic modulus, Sry= K1 - K2.n2, for minor axis bending.
