Buckling resistance of steel-concrete columns composed of high-strength materials

Popis výsledku v původním jazyce

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 the load-carrying capacity of members in the case of simple compression, because of their high strengths. In the case of the buckling the load-carrying capacity is significantly influenced by the stiffness (through the slenderness) dependent on the modulus of elasticity. For steel the modulus of elasticity is the same regardless of steel grade, in thecase of high-strength concrete the modulus of elasticity increases slowly compared with the strength increasing, so that can influence the buckling resistance negatively. This paper presents brief information and some results of experime
