Compressed Concrete Filled Steel Tube Elements of Annular Cross-Section
The problem of determining the strength of a short centrally compressed concrete-filled steel tube element of annular cross-section is considered. The corresponding calculation procedure is proposed. The procedure is based on the theoretical positions of the mechanics of solids and it implements th...

The problem of determining the strength of a short centrally compressed concrete-filled steel tube element of annular cross-section is considered. The corresponding calculation procedure is proposed. The procedure is based on the theoretical positions of the mechanics of solids and it implements the method of limiting forces. It considers the complex stress state of the concrete core and steel shell as well as nonuniform distribution of transversal stresses over the cross-section of the calculated element. If there is high-strength reinforcement in the concrete, the stress in it is calculated considering the increased deformability of the concrete. The dependences for determining the initial modulus of elasticity of concrete as well as ultimate relative strains of uniaxially compressed and volumetrically compressed concrete are presented. The proposed procedure is applicable to structures made of different concrete types and steel classes.
