The Structural Use of Steelwork in Building
PREFACE
The low usage of structural steel in India is attributable in part to the prevailing out-of-date design practices, which result in uneconomic designs. The relevant Indian Codes of Practice (IS: 800 - 1984, IS: 801 - 1975) applicable to the structural use of hot-rolled and cold-rolled steel are largely based on "Working Stress Method". The more modern "Limit State Design Approach" developed in the 1970's in the West, is technologically sound and results in significant economies in completed structures. This is of particular advantage, as steel is reusable and environment friendly. Compared with competing materials of construction, steel framed buildings have significantly better blast and earthquake resistance and take less than half the time to build. In passing, it may be noted that the Indian Codes of Practice applicable to concrete structures have been revised to conform to Limit State Methodology. This makes the choice of steel in construction an uneconomic proposition. It is also noted that the Code of Practice for steel-concrete-composite buildings (IS: 11384 - 1985) is based on the Limit State approach but is very limited in its coverage, besides being inconsistent with IS: 800 and IS: 801 written in Working Stress format.
