| 1 | In this revision, therefore, the following major modifications have been made: a) The working stress design has been discontinued due to the increasing familiarity of designers with the limit state design of steel structures. b) The table on tensile properties of structural steel products has been updated by including the Indian Standards relating to structural steels and aligning the corresponding provisions of the table with those given in IS 2062 : 20xx ‘Hot rolled low, medium and high tensile structural steel (eighth revision)’. | |
| 2 | g) Provisions related to the consideration of second order effects have been updated. h) Provisions related to design for earthquake loads relating to load and load combinations, various types of frames and connections in the critical zones of frames have been updated. j) Provisions related to bracing connections have been updated. k) Provisions related to fabrication procedures have been updated. m) Certain terminologies, symbols and figures have been updated based on the changes incorporated. n) Buckling class of cross section table has been updated. p) Imperfection parameter for lateral torsional buckling of beam has been added. | |
| 3 | q) A new clause on sustainable steel construction has been added. This provision covers the following: 1) Requirements from Engineers, contractors and supply chain members, 2) Sustainable design process by minimizing the materials, fabrication; and avoidance of maintenance, 3) Design for adaptability and deconstruction, etc. r) The detailed provision relating to design of anchor bolts have been introduced in Annex G. s) The detailed provision relating to design of corrugated web girder has been introduced in Annex H. | |
