Abstract

With assessing the extent of fire damage to a two-story building occupied by a textile factory. The slabs are composed of pretensioned 1.2m width, 9.0m length slender panels, supported by prestressed concrete beams. The remaining structural elements are of reinforced concrete. The study throws light upon fire investigation tools utilized to evaluate the post fire integrity of the structure. It also describes fire investigation techniques that track the visual evidence in the fire-damaged structure. The study also includes estimating the peak temperature and duration of heat. The assessment involves both field and laboratory work to determine the severity of the damage. The work involves nondestructive testing throughout the parts of the building that were still in place and appear to be stable, followed by destructive testing at some selected locations. This paper presents an overview of how to conduct a structural evaluation of a fire damaged structure.
