IS 800 : 2007 General Construction in Steel

This Indian Standard (Third Revision) was adopted by the Bureau of Indian Standards, after the draft finalized by the Structural Engineering and Structural Sections Sectional Committee had been approved by the Civil Engineering Division Council.

The steel economy programme was initiated by erstwhile Indian Standards Institution in the year 1950 with the objective of achieving economy in the use of structural steel by establishing rational, efficient and optimum standards for structural steel products and their use. IS 800: 1956 was the first in the series of Indian Standards brought out under this programme. The standard was revised in 1962 and subsequently in 1984, incorporating certain very importmt changes.

IS 800 is the basic Code for general construction in steel structures and is the prime document for any structural design and has influence on many other codes governing the design of other special steel structures, such as towers, bridges, silos, chimneys, etc. 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. Consideration has been given to the de~elopments taking place in the country and abroad, and necessary modifications and additions have been incorporated to make the standard more useful.

IS 456:2000 Plain and Reinforced Concrete

This Indian Standard (Fourth Revision) was adopted by the Bureau of Indian Standards, after the draft finalized . by the Cement and Concrete Sectional Committee had been approved by the Civil Engineering Division Council. This standard was first published in 1953 under the title ‘Code of practice for plain and reinforced concrete for general building construction’ and subsequently revised in 1957. The code was further revised in 1964 and published under modified title ‘Code of practice for plain and reinforced concrete’,thus enlarging the scope of use of this code to structures other than general building construction also. The third revision was published in 1978, and it included limit state approach to design. This is the fourth revision of the  standard. This revision was taken up with a view to keeping abreast with the rapid development in the field of concrete technology and to bring in further modifications/improvements in the light of experience gained while using the earlier version of the standard.

1 SCOPE

1.1 This standard deals with the general structural use of plain and reinforced concrete. 

1.1.1 For the purpose of this standard,plain concrete structures are those where reinforcement,if provided is ignored for determination of strength of the structure. 

1.2 Special requirements of structures,such as shells, folded plates,arches.bridges,chimneys,blast resistant structures, hydraulic structures, liquid retaining structures and earthquake resistant structures,covered in respective standards have not been covered in this standard;these standards shall be used in.conjunction with this standard.

IS :1199-1959 Method of Sampling and Analysis of Concrete

0.1 This Indian Standard was adopted by the Indian Standards Institution on 10 November 1,959, after the draft finalized by the Cement and Concrete Sectional Committee had been approved by the Building Division Council.

.2 Testing plays an important role in controlling the quality of cement concrete work. Systematic testing of the raw materials for concrete as also, the concrete, both while it is fresh and after it has hardened, is an inseparable part of any quality control programme for concrete. It helps to achieve higher efficiency of the materials used and greater assurance of the performance of the concrete in regard to both strength and durability. The test methods used should be simple, direct and convenient in their application. This standard has been prepared with this object in view and provides a guide to the sampling, analysis, and determination of linear changes of concrete. Strength tests for concrete have been covered separately in IS : 516-1959 Methods of Tests for Strength of Concrete …
