The paper deals with some problems of the actual behaviour and buckling resistance of steel-concrete compression members composed of high-strength steel and high-performance concrete. Especially, this paper is directed towards the steel-concrete composite columns of the dimensions used usually for columns of multi-storey buildings. High-strength materials (steel and concrete, too) can effectively increase in the resistance of columns in the case of simple compression, because of their high strengths. In the case of the buckling the resistance is significantly influenced by the stiffness (through the slenderness) dependent on the Young's modulus of elasticity. For steel the modulus of elasticity is the same regardless of steel grade, in the case of high-strength concrete the modulus of elasticity increases more slowly compared with the strength increasing, so that Young's modulus of both materials can influence the buckling resistance negatively. This paper presents brief information and some selected results of experimental and theoretical analysis oriented to the usage of high-strength steel and high-strength concrete in composite columns, for the particular example of the typical steel-concrete sections - open H-sections encased between flanges.
