Local stability of the steel tubes with concrete core

The paper deals with the experimental analysis of the local stability of short axially compressed rectangular concrete-filled steel tubes (CFSTs), in which the load acted on the steel pipe. This analysis is one part of the research oriented to the local and global stability of rectangular concrete-filled steel tubes. This part presents the comparison of the coefficients of critical stress, which were obtained from experimental tests of investigated members with standard value in Eurocode 3. Some results and research findings of this analysis are published in the paper.
