Diagnostics of Concrete Elements After the Fire
Diagnostics of Concrete Elements After the Fire is a scholarly work, published in 2018 in ''Structure and Environment''. The main subjects of the publication include architectural engineering, forensic engineering, environmental science, structural engineering, and engineering. The paper presents selected methods for determining the influence of fire on the load capacity of concrete elementsdiagnostics and damages arising after application of fire temperatures.The subject may not seem new in terms of the wellknown drop in the strength of concrete in fire conditions, but an important aspect discussed in the paper is the fracture toughness of concrete depending on high temperatures.Destructions, caused by fire temperatures, affects the physical and mechanical properties of concrete, and their size can be assessed using the stress intensity factor.According to the authors' own research, the critical stress intensity factor K IC of concrete decreases faster than the dynamic modulus of elasticity, and also faster than compressive and tensile strength.The paper describes selected methods of diagnostics of construction elements from concrete damaged by fire.
