The Institute said that concrete alone has almost nil ductility, while structural steel has the best ductile properties among other building materials. It suggested that higher priority be given for use of steel in construction work. Use of structural steel has now become very normal as basic raw materials for building construction in advanced countries. In other cases the country uses exhaustive earthquake resistant design. Similarly more than 90 per cent of single-storey buildings in the United Kingdom are steel framed.
Advanced countries use steel about three to five times more than cement compared to India.
