Retrofitting of Fire Affected Structural Member in Multistorey Buildings

Abstract

 with the increased incidents of major fires in buildings; assessment, repairs and rehabilitation of fire damaged structures has become a topical interest. This is a specialized field involves expertise in many areas like concrete technology, material science and testing, structural engineering, repair materials and techniques etc. Research and developmental efforts are being carried out in this area and other related disciplines.

In this paper, 8th Storey R.C.C framed structure is considered for performing analysis and design as per relevant Indian Standards codal provisions. The modeling, linear static analysis, and design is to be performed using FE software package sap2000. For analysis the structure is subjected to fire loads in terms of temperature loading at different storey's. Due to temperature loading the strength of column is been reduced, so for re-strengthening of column retrofitting technique is to be carried out.
