"The paper is focused on the usage of high-strength materials in steel and steel-concrete compression members from the viewpoint of the buckling (global and local buckling, respectively), in comparison with compression members composed of normal materials. High-strength steel and high-performance concrete can increase the member resistance in the case of simple compression, because of their high strengths, but the buckling resistance can be significantly influenced by the stiffness (through the slenderness) dependent on the modulus of elasticity. The steel modulus of elasticity is the same regardless of steel grade, the concrete modulus of elasticity increases, but more slowly than the strength increasing, so that can influence the buckling resistance negativelly.
