Practical Reliability-Based Calculation Tool for the Post-Fire Assessment of Concrete Beams

Abstract

If a structure has been able to maintain stability during fire exposure, the residual load-bearing capacity of the structural elements after fire should be determined when deciding upon the further use of the structure. Since adequate safety is a primary requirement for all structures and since many uncertainties are associated with the post-fire assessment, only a reliability-based assessment can be acceptable for real-life applications. In this contribution an easy-to-use reliability-based tool is presented for the post-fire assessment of the load-bearing capacity of concrete beams
