Effect of probabilistic strength retention factors for steel and concrete on structural reliability of columns in fire

Abstract
With the advent of performance based design within the domain of structural fire safety, there is a need for an increased level of confidence in properties of construction materials. As test data depict a significant scatter in temperature dependent material strengths of steel and concrete, systematic quantification of this variability is important for application within performance based fire engineering. The objective of this research is to examine different stochastic models to quantify uncertainty in steel and concrete strengths at elevated temperature. Based upon a collection of experimental data from literature, different probabilistic models are proposed for the retention factors of steel yield strength and concrete compressive strength, which are then compared based on application to the structural fire performance of columns under fire. This research improves understanding of effects of model choice for material uncertainties on the structural fire response.
