Structural Sections Committee, SDC FOREWORD This Indian Standard (Third Revision) was adopted by the Bureau of Indian Standards on April 199, after the draft finalized by the Structural Sections Committee had been approved by the Structural and etals Division Council. Under the steel economy programme, a rational, efficient and economical series of Indian Standards on beam sections, channel sections and angle sections was evolved in 197 and IS 0 : 197 was published covering junior, light weight, medium weight, wide flange and heavy weight beam sections; junior, light weight and medium weight channel sections and equal and unequal leg angle sections. This standard was revised in 194. In the second revision of this standard, parts relating to medium weight beam sections B series, column sections SC series, channel sections C and CP series and equal and unequal leg angles were revised and published as Parts 1, 2, 3, and of IS 0, respectively. Sections not covered in these parts, however continued in IS 0 : 194. In the present revision, the Committee felt it convenient to merge all the five parts into one standard. The sections which were retained in IS 0 : 194 subsequent to its second revision in five parts are included in this standard with a view that these sections although not being rolled in the country at present may in future be rolled owing to their efficiency and resultant economy in the use of steel. However, the designers are advised to check from JPC/producers regarding availability of such sections. Following additional modifications have been affected in this revision: a) edium weight beam sections B 100 having the flange width and web thickness of 70 mm and 4. mm, respectively, has been modified to 0 mm flange width and 4.7 mm web thickness; b) Two sections, namely, BFB 10 and RSJ 200 which are mainly used in railway electrification have been included as SC 10 and WB 200, respectively; c) Additional equal leg angles 0 0 4, 100 100 7 (in place of 100 100.), and 130 130 9 have been included in the supplimentary list; d) Amendments issued so far to the various parts of the standard and to IS 0 : 194 have been incorporated; and e) ass, 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 the text as the result of incorporation of the amendment.
Indian Standard DIENSIONS FOR HOT ROLLED STEEL BEA, COLUN, CHANNEL AND ANGLE SECTIONS ( Third Revision ) 1 SCOPE This standard covers the nominal dimensions, mass and sectional properties of hot rolled sloping flange beam and column sections, sloping and parallel flange channel sections and equal and unequal leg angle sections. 2 REFERENCES The Indian Standard IS 12 : 19 Rolled and cutting tolerances for hot rolled steel products ( fourth revision ) is a necessary adjunct to this standard. SECTION 1 GENERAL 3 TERINOLOGY 3.1 Y-Y Axis A line parallel to the axis of the web of the section (in the case of beams and channels) or parallel to the axis of the longer flange (in the case of unequal angles) or either flange (in the case of equal angles) and passing through the centre of gravity of the profile of the section. 3.2 X-X Axis A line passing through the centre of gravity of the profile of the section, and at right angles to the Y-Y axis. 3.3 U-U and V-V Axes Lines passing through the centre of gravity of the profile of the section, representing the principal axes of angle sections. 4 SYBOLS 4.1 Letter symbols used in this standard have been indicated appropriately in Sections 2 to. ore explicit definitions for certain symbols, used in the figures and tables of Sections 2 to are given in 4.1.1 and 4.1.2. 4.1.1 Symbols for A, B = the longer and the shorter leg length of angle section, respectively; B D R 1 R 2 t T = flange width of beam, column or channel sections; = depth of beam, column or channel section; = radius at fillet or root; = radius at toe; = thickness of web of beam, column or channel section; thickness of leg of angle section; and = thickness of flange of beam, column or channel section. 4.2.2 Symbols for a = sectional area, C ( with subscripts x, y, u or v ) = distance of centre of gravity, C x = A e x, C y = B e y, e x = distance of extreme fibre from X-X axis, e y = distance of extreme fibre from Y-Y axis, I x = moment of inertia about X-X axis, I y = moment of inertia about Y-Y axis, I u = moment of inertia ( ax ) about U-U axis, I v = moment of inertia ( in ) about V-V axis, = mass of the section per metre length, I x Z x = ---- = e x I y e y Z y = ---- = I x modulus of section about X-X axis, modulus of section about Y-Y axis, radius of gyration about X-X r x = ---- = a axis, 1
radius of gyration about Y-Y r y = ---- = a axis, I radius of gyration about U-U r u = ---- u = a axis, radius of gyration about V-V r v = ---- = a axis, α I y I v = angle between U-U and X-X axes of angle section; slope of flange in the case of beam, column or channel. CLASSIFICATION.1 Beam, column, channel and angle sections are classified as follows:.1.1 Beams a) Indian Standard junior beams (ISJB) b) Indian Standard light weight beams (ISLB) c) Indian Standard medium weight beams (ISB) d) Indian Standard wide flange beams (ISWB).1.2 Columns/Heavy Weight Beams a) Indian Standard column sections (ISSC) b) Indian Standard heavy weight beam (ISHB).1.3 Channels a) Indian Standard junior channels (ISJC) b) Indian Standard light weight channels (ISLC) c) Indian Standard medium weight channels (ISC) d) Indian Standard medium weight parallel flange channels (ISCP). Angles a) Indian Standard equal leg angles (ISA) b) Indian Standard unequal leg angles (ISA).2 The following abbreviated reference symbols have been used in designating the Indian Standard sections mentioned in.1: Section Beams Columns/heavy beams Channels Classification Abbreviated Reference Symbol ISJB ISLB ISB ISWB ISSC ISHB ISJC ISLC ISC ISCP JB LB B WB SC HB JC LC C CP Angles ISA DESIGNATION.1 Beam, columns and channel sections shall be designated by the respective abbreviated reference symbols followed by the depth of the section, for example: a) B 200 for a medium weight beam of depth 200 mm, b) SC 200 for a column section of depth 200 mm, c) C 200 for medium weight channel of depth 200 mm, and d) CP 200 for a medium weight parallel flange channel of depth 200 mm..2 Equal and unequal leg angles shall be designated by the abbreviated reference symbols () followed by the dimensions A, B and t. For example, 200 100 10 represents unequal leg angle of dimensions 200 mm, 100 mm and thickness 10 mm. 7 DIENSIONS, ASS AND TOLERANCES 7.1 Nominal dimensions and mass of beam, column, channel and equal and unequal angles shall conform to the values given in Sections 2, 3, 4, and, respectively of the standard. 7.2 Dimensional and mass tolerances of the various sections shall conform to the appropriate values stipulated in IS 12 : 19. SECTIONAL PROPERTIES properties of the beams, columns, channel and equal and unequal leg angles are given in Sections 2 to for information. 2
