A Review of Seismic Evaluation and Strengthening of R.C Framed Structure

Abstract

Late tremors in India demonstrate that non-built as well as designed structures in our nation are powerless even to direct quakes. Indian Standard IS 1893 is overhauled in 2002. Various structures those were planned according to the past code may not conform to the present code. Along these lines assessing seismic execution of a structure and proposing reasonable retrofit measure is a significant zone of concentrate in this specific circumstance. In the present examination an endeavor has been made to assess a current structure situated in Bhopal (seismic zone V) utilizing proportional static investigation. Indian Standard IS-1893:2002 (Part-1) is pursued for the comparable static examination methodology. Building is displayed in business programming STAAD Pro. Seismic power interest for every individual part is determined for the plan base shear as required by Seems to be 1893:2002. Relating part limit is determined according to Indian Standard IS456:2000. Insufficient individuals are distinguished through interest to-limit proportion. Various shafts and segment components in the primary floor of the present structure are observed to be inadequate that needs retrofitting. A neighborhood retrofitting procedure is embraced to redesign the limit of the insufficient individuals. This investigation demonstrates that steel jacketing is a proficient method to retrofit RC individuals to improve flexure just as shear limit.
