Structural Sections Sectional Committee, SMDC 6

FOREWORDThis Indian Standard (Third Revision) was adopted by the Bureau of Indian Standardson 6 April 1989, after the draft finalized by the Structural Sections Sectional Committee had beenapproved by the Structural and Metals Division Council.

Under the steel economy programme, a rational, efficient and economical series of IndianStandards on beam sections, channel sections and angle sections was evolved in 1957 andIS 808 : 1957 was published covering junior, light weight, medium weight, wide flange and heavyweight beam sections; junior, light weight and medium weight channel sections and equal andunequal leg angle sections. This standard was revised in 1964.

In the second revision of this standard, parts relating to medium weight beam sections — MBseries, column sections — SC series, channel sections — MC and MCP series and equal andunequal leg angles were revised and published as Parts 1, 2, 3, 5 and 6 of IS 808, respectively.Sections not covered in these parts, however continued in IS 808 : 1964.

In the present revision, the Sectional Committee felt it convenient to merge all the five parts intoone standard. The sections which were retained in IS 808 : 1964 subsequent to its second revisionin five parts are included in this standard with a view that these sections although not being rolledin the country at present may in future be rolled owing to their efficiency and resultant economy inthe use of steel. However, the designers are advised to check from JPC/producers regardingavailability of such sections.

Following additional modifications have been affected in this revision:a) Medium weight beam sections MB 100 having the flange width and web thickness of 70 mm

and 4.5 mm, respectively, has been modified to 50 mm flange width and 4.7 mm webthickness;

b) Two sections, namely, BFB 150 and RSJ 200 which are mainly used in railway electrificationhave been included as SC 150 and WB 200, respectively;

c) Additional equal leg angles 60 60 × 4, 100 100 × 7 (in place of 100 100 × 6.5), and 130 130 × 9have been included in the supplimentary list;

d) Amendments issued so far to the various parts of the standard and to IS 808 : 1964 have beenincorporated; and

e) Mass, area and other sectional properties have been expressed in three significant places.

This edition 4.1 incorporates Amendment No. 1 (July 1992). Side bar indicates modification of thetext as the result of incorporation of the amendment.

DIMENSIONS FOR HOT ROLLED STEEL BEAM, COLUMN, CHANNEL AND

ANGLE SECTIONS

( Third Revision )1 SCOPE

This standard covers the nominal dimensions,mass and sectional properties of hot rolledsloping flange beam and column sections,sloping and parallel flange channel sectionsand equal and unequal leg angle sections.

2 REFERENCES

The Indian Standard IS 1852 : 1985 ‘Rolled andcutting tolerances for hot rolled steel products( fourth revision )’ is a necessary adjunct to thisstandard.

SECTION 1 GENERAL

3 TERMINOLOGY

3.1 Y-Y Axis

A line parallel to the axis of the web of thesection (in the case of beams and channels) orparallel to the axis of the longer flange (in thecase of unequal angles) or either flange (in thecase of equal angles) and passing through thecentre of gravity of the profile of the section.

3.2 X-X Axis

A line passing through the centre of gravity ofthe profile of the section, and at right angles tothe Y-Y axis.

3.3 U-U and V-V Axes

Lines passing through the centre of gravity ofthe profile of the section, representing theprincipal axes of angle sections.

4 SYMBOLS

4.1 Letter symbols used in this standard havebeen indicated appropriately in Sections 2 to 6.More explicit definitions for certain symbols,used in the figures and tables of Sections 2 to 6are given in 4.1.1 and 4.1.2.

4.1.1 Symbols for Dimensions

4.2.2 Symbols for Sectional Properties

A, B = the longer and the shorter leg lengthof angle section, respectively;

B = flange width of beam, column orchannel sections;

D = depth of beam, column or channelsection;

R1 = radius at fillet or root;

R2 = radius at toe;

t = thickness of web of beam, column orchannel section; thickness of leg ofangle section; and

T = thickness of flange of beam, columnor channel section.

a = sectional area,

C ( with subscripts x, y, u or v )

= distance of centre of gravity,

Cx = A – ex,

Cy = B – ey,

ex = distance of extreme fibre from X-Xaxis,

ey = distance of extreme fibre from Y-Yaxis,

Ix = moment of inertia about X-X axis,

Iy = moment of inertia about Y-Y axis,

Iu = moment of inertia ( Max ) about U-Uaxis,

Iv = moment of inertia ( Min ) about V-Vaxis,

M = mass of the section per metre length,

Zx = =modulus of section about X-Xaxis,

Zy = = modulus of section about Y-Yaxis,

rx = =radius of gyration about X-Xaxis,

5 CLASSIFICATION

5.1 Beam, column, channel and angle sectionsare classified as follows:

5.1.1 Beams

a) Indian Standard junior beams (ISJB)

b) Indian Standard light weight beams(ISLB)

c) Indian Standard medium weight beams(ISMB)

d) Indian Standard wide flange beams(ISWB)

5.1.2 Columns/Heavy Weight Beams

a) Indian Standard column sections (ISSC)

b) Indian Standard heavy weight beam(ISHB)

5.1.3 Channels

a) Indian Standard junior channels (ISJC)

b) Indian Standard light weight channels(ISLC)

c) Indian Standard medium weight channels(ISMC)

d) Indian Standard medium weight parallelflange channels (ISMCP)

5.1.4 Angles

a) Indian Standard equal leg angles (ISA)

b) Indian Standard unequal leg angles (ISA)

5.2 The following abbreviated referencesymbols have been used in designating the

Indian Standard sections mentioned in 5.1:

6 DESIGNATION

6.1 Beam, columns and channel sections shallbe designated by the respective abbreviatedreference symbols followed by the depth of thesection, for example:

a) MB 200 — for a medium weight beam ofdepth 200 mm,

b) SC 200 — for a column section of depth200 mm,

c) MC 200 — for medium weight channel ofdepth 200 mm, and

d) MCP 200 — for a medium weight parallelflange channel of depth 200 mm.

6.2 Equal and unequal leg angles shall bedesignated by the abbreviated referencesymbols (∠ ) followed by the dimensions A, Band t. For example, 200 100 × 10 representsunequal leg angle of dimensions 200 mm,100 mm and thickness 10 mm.

7 DIMENSIONS, MASS AND TOLERANCES

7.1 Nominal dimensions and mass of beam,column, channel and equal and unequal anglesshall conform to the values given in Sections 2,3, 4, 5 and 6, respectively of the standard.7.2 Dimensional and mass tolerances of thevarious sections shall conform to theappropriate values stipulated in IS 1852 : 1985.

8 SECTIONAL PROPERTIES

Sectional properties of the beams, columns,channel and equal and unequal leg angles aregiven in Sections 2 to 6 for information.

ry = =radius of gyration about Y-Yaxis,

ru = =radius of gyration about U-Uaxis,

rv = =radius of gyration about V-Vaxis,

α = angle between U-U and X-X axes ofangle section; slope of flange in the caseof beam, column or channel.

NOTE — HB sections are also used as column sections.

*These heavier sections in each size are obtained from the same set of rolls as the lighter sections by spreading of the rolls. The width of flanges of these sections gets increased byan amount equal to the difference between the thicknesses of the webs. Therefore, while ordering these heavier sections, mass should be mentioned.
