Post-fire reduction of concrete's mechanical properties and its impact on residual load capacity
This paper investigates the reduction of mechanical properties of four different light-weight concrete mixes containing expanded clay aggregate in a short time period after exposure to high temperature regime. The research has shown that compressive strength exhibits additional reduction up to 10-20%, 96 hours after being cooled down to ambient temperature. A numerical example of simply supported concrete column exposed to standard fire from four sides is given, illustrating the effects of post-fire strength reduction on residual load capacity. The results obtained indicate that the effect of short-term reduction of the compressive strength of concrete in real structures damaged by fire could have a significant effect on the post-fire load bearing capacity of structures and should be accounted for in the engineering building codes.
