Abstract:The paper deals with the behaviour of steel tubular columns filled by high-strength concrete at compression load. Attention is paid especially to the strength of the used concrete and its effect on the buckling resistance of column. Results of the experimental part of research have shown that increasing of concrete strength is efficient only to a certain extent. It was found in the experimental analysis that the use of concrete class C80/95 has only little effect on increase of buckling resistance as compared … Show more
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.
