IS 800 : 2007 General Construction in Steel - Code of Practice

ICS 77.140.01 CED 7
Reaffirmed 2017

1.1 Scope

1.1.1 This standard applies to general constructionusing hot rolled steel sections joined using riveting,bolting and welding. Specific provisions for bridges,chimneys, cranes, tanks, transmission line towers, bulkstorage structures, tubular structures, cold formed lightgauge steel sections, etc, are covered in separatestandards.

1.1.2 This standard gives only general guidance as regardsthe various loads to be considered in design. For the actualloads and load combinations to be used, reference maybe made to IS 875 for dead, live, snow and wind loadsand to IS 1893 (Part 1) for earthquake loads.

1.1.3 Fabrication and erection requirements coveredin this standard are general and the minimum necessaryquality of material and workmanship consistent withassumptions in the design rules. The actualrequirements may be further developed as per otherstandards or the project specification, the type ofstructure and the method of construction.

1.1.4 For seismic design, recommendations pertainingto steel frames only are covered in this standard. Formore detailed information on seismic design of otherstructural and non-structural components, refrenceshould be made to IS 1893 (Part 1) and other specialpublications on the subject.
