COMPARISON OF PERCENTAGE STEEL AND CONCRETE QUANTITIES OF A R.C BUILDING IN DIFFERENT SEISMIC ZONES

This paper addresses the performance and variation of percentage steel and concrete quantities of R.C.C framed structure in different seismic zones. One of the most frightening and destructive phenomena of a nature is a severe earthquake and it terrible after effect. It is highly impossible to prevent an earth quake from occurring, but the damage to the buildings can be controlled through proper design and detailing. Hence it is mandatory to do the seismic analysis and design to structures against collapse. Designing a structure in such a way that reducing damage during an earthquake makes the structure quite uneconomical, as the earth quake might or might not occur in its life time and is a rare phenomenon. The present IS code 1893:2002 doesn’t provide information about the variation of concrete and percentage of steel from zone to zone. This study mainly focus on the comparison of percentage steel and concrete quantities when the building is designed for gravity loads as per IS 456:2000 and when the building is designed for earthquake forces in different seismic zones as per IS 1893:2002
