Designator of Legally Binding Document: IS Title of Legally Binding Document: General Construction In Steel - Code of Practice Number. This standard applies to general construction using hot rolled steel sections joined using riveting, bolting and welding. Specific provisions for bridges, chimneys. IS is an Indian Standard code of practice for general construction in steel. The earlier Print/export. Create a book · Download as PDF · Printable version.

Plans shall indicate the type of construction to be employed; and shall be supplemented by such data on the assumed loads, shears, moments and axial forces to be resisted by all members and their connections, as may be required for the proper preparation of shop drawings.

Any special precaution to be taken in the erection of structure, from the design consideration shall also be indicated in the drawing. They shall clearly distinguish between shop and field rivets, bolts and welds.

For additional information to be included on drawings for designs based on the use of welding, reference shall be made to appropriate Indian Standards. Shop drawings shall be made in conformity with IS A marking diagram allotting distinct identification marks to each separate part of steel work shall be prepared.

The diagram shall be sufficient to ensure convenient assembly and erection at site. However, such steels may be used in structural system after confirming their quality by carrying out appropriate tests in accordance with the method specified in IS Except for notch toughness, the other properties are determined by conducting tensile tests on samples cut from the plates, sections, etc, in accordance with IS Commonly used properties for the common steel products of different specifications are summarized in Table 1.

I Stress at 0. They may also be manufactured from steel conforming to IS provided that the steel meets the requirements given in IS The recommendations in IS shall be followed.

The combination of wire and flux shall satisfy the requirements of IS With an appropriate degree of safety, they should sustain all the loads and deformations, during IS Structure should be stable and have alternate load paths to prevent disproportionate overall collapse under accidental loading. Account should be taken of accepted theories, experimental information and experience and the need to design for dumbi]ity.

Calculations alone may not produce Safe, serviceable and durable structures. Suitable materials, quality control, adequate detailing and good supervision are equally important. The realization of design objectives requires compliance with clearly defined standards for materials, fabrication, erection and in-service maintenance. Imposed loads arising 15 Snow load shall be taken as per IS Part 4.

Proper provision shall be made, including temporary bracings, to take care of all stresses developed during erection. Dead load, wind load and also such parts of the live load as would be imposed on the stricture during the period of erection shall be taken as acting together with the erection loads.

The structure as a whole and all parts of the structure in conjunction with the temporary bracings shall be capable of sustaining these loads during erection. The absolute maximum and minimum temperatures, which may be expected in different localities of the country, may be obtained from the Indian Metrological Department and used in assessing the maximum variations of temperature for which provision for expansion and contraction has to be made in the structure.

This difference in temperature variations of the material and air shall be given due consideration. The effect of differential temperature within an element or member, due to part exposure to direct sunlight shall also be considered.

The following combination of loads with appropriate partial safety factors see Table 4 maybe considered. NOTE — In the case of structures supporting crmres, imposed loads shall include the crane effects as given in 3.

The effect of each shall be considered separately. In the absence of any specific indications, the load combinations shall be in accordance with the provisions in IS Part 2 or as given below: The effect of each force, shall however be investigated separately.

In case of punched holes, hole size 2 mm in excess of the actual diameter may be deducted. The local buckling can be avoided before the limit state is achieved by limiting the width to thickness ratio of each element of a cross-section subjected to compression due to axial force, moment or shear.

The width to thickness ratio of plate elements shall be less than that specified under Class 1 Plastic , in Table 2. The width to thickness ratio of plate elements shall be less than that specified under Class 2 Compact , but greater than that specified under Class 1 Plastic , in Table 2. The width to thickness ratio of plate elements shall be less than that specified under Class 3 Semi-compact , but greater than that specified under Class 2 Compact , in Table 2.

The width to thickness ratio of plate elements shall be greater than that specified under Class 3 Semi-compact , in Table 2. In such cases, the effective sections for design shall be calculated either by following the provisions of IS to account for the post-local-buckling strength or by deducting width of the compression plate element in excess of the semi-compact section limit.

When different elements of a cross-section fall under different classes, the section shall be classified as governed by the most critical element. The maximum value of limiting width to thickness ratios of elements for different classifications of sections are given in Table 2. Outside elements or outstands — These are elements attached along only one of the longitudinal edges to an adjacent element, the other edge being free to displace out of plane, for example flange overhang of an I-section, stem of T-section and legs of an angle section.

Tapered elements — These maybe treated as flat elements having average thickness as defined in SP 6 Part 1. In such cases the section is classified based on the least favorable classification.

Reference may be made to IS for such design provisions. The design of slender web elements may be made as given in 8. To resist torsional effects of wind and earthquake forces, bracings in plan should be provided and integrally connected with the longitudinal and transverse bracings, to impart adequate torsional resistance to the structure. Where the connections to the interior columns or frames are designed such that the wind or earthquake loads will not be transferred to the interior columns, the exterior columns or frames shall be designed to resist the total wind or earthquake loads.

Where the connections to the interior columns and frames are designed such that the wind or earthquake effects are transferred to the interior columns also, and where adequate rigid diaphragm action can be mobilized as in the case of the cast-in place RC slab, both exterior and interior columns and frames may be designed on the assumption that the wind or earthquake load is divided among them in proportion to their relative stiffness.

Columns also should be designed to withstand the net uplifting effect caused by excessive wind or earthquake. Additional axial forces arising in adjacent columns due to the vertical component of bracings or due to frame action shall also be accounted for.

Earthquake forces should be applied at the centre of gravity of all such components of mass and their transfer to the foundation should be ensured. Other construction details, stipulated in IS should also be followed.

Expansion joints shall be so provided that the necessary movement occurs with minimum resistance at the joint. The gap at the expansion joint should be such that: Four-sided jire exposure condition — Steel 1. Lirnit State — A limit state of acceptable service condition exceedence of which causes serviceability failure.

Realising the necessity to update the standard to the state of the art of the steel construction technology and economy, the current revision of the standard was undertaken. IS The relationship between the degree of flexural restraint and the level of the load effects shall be established by any rational method or based on test results see Annex F.

The width to thickness ratio of plate elements shall be less than that specified under Class 3 Semi-compact , but greater than that specified under Class 2 Compact , in Table 2. Reference may be made to IS for such design provisions. The maximum value of limiting width to thickness ratios of elements for different classifications of sections are given in Table 2.
