PROGRESSIVE COLLAPSE ANALYSIS OF EXISTING RC FRAMED STRUCTURE WITH DESIGN OF EXTERNALLY BONDED FRP SYSTEM

Abstract

when a building gets too old or exposed to any natural hazards say Tsunami or Earthquake or due to manmade hazards such as fire, explosion of gases, impact of vehicles, etc, it effects the behavior of structure and causes collapse of all or a large part of a structure precipitated by failure or damage of a relatively small part of it. A building undergoes progressive collapse when a primary structural element fails, resulting in the failure of adjoining structural elements, which in turn causes further structural failure. In this present study the behavior of existing RC framed building with 3 stories to progressive collapse located in seismic zone iii is investigated. A linear static analysis is worked out using ETABS software respectively. The demand capacity ratio is assessed in the critical region of the RC portion associated with the column removed, as per provisions of GSA guidelines. The paper concluded that the design of Externally bonded fiber reinforced polymer (FRP) composite laminates have been successfully applied to reinforced concrete (RC) beams and other structural elements there is less susceptibility of progressive collapse with ACI 440 2R- 08 and ISIS CANADA as per the provision of guidelines
