Post-fire damage assessment and capacity based modeling of concrete exposed to elevated temperature

Abstract: Fire represents one of the significant hazards encountered by civil infrastructures, and thus providing appropriate fire safety measures is a major requirement in a building design for ensuring the safety of the occupants. Minimizing fire-induced damage and collapse of structural systems are the primary objectives in the design of concrete structures. An experimental investigation has been carried out to examine the mechanical properties such as compressive, tensile and flexural strengths of concrete exposed t… Show more

“…The higher concrete grade suffers higher strength loss [14]. The heating rate and time of exposure affects concrete performance in fire [15]. The concrete suffers negligible up to 200 °C as only free water evaporates (exceptions are also reported [16]), at 300 °C bounded water starts evaporating, thus, CHS starts irreversibly dehydrating.…”

“…The compressive strength of concrete can hence reduce down to 90 % at 750 °C [19]. A multitude of parameters, however, like the nature and setup of the experiments, or the mix design parameters, highly govern these findings [15].…”
