The paper presents a study of fire behaviour of butt-welded connections taken into account the post fire conditions and the possibility of welding strengthening of fire exposed structures. The need of in service life of a steel structure after being exposed to fire raises the problem of strengthening or replacement of some structural elements. The degradation of steel properties with increasing temperature is considered according to Eurocode 3: Part 1-2 provisions. Following the experimental part, the behavior of the welded connections after fire exposure was compared with the original behaviour at the ambient temperature. The results and conclusions can be used for damage assessment and strengthening technique of post fire steel structure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
