Abstract

Many researches agreed about behaviour of loaded Concrete Filled Steel Tube (CFST) element that in loading stage, when exist particular level of stresses, appear interaction between steel tube and concrete core and wherefore appear complex stress state of element, which increases strength of whole composite element. In this article are analysed reasons of above mentioned complex stress state and behaviour of CFST element components in different states of compressed structural member.
