Original Abstract

The paper deals with the problems of the theoretical and experimental investigation of the buckling resistance of steel and steel-concrete columns composed of high-strength materials. The paper presents selected results of the more extensive research realized on the authors workplace and oriented to the utilization of high-strength steels and high-performance concretes in steel structural members and composite structural members composed of steel and concrete. This paper is directed towards one part of this research only that means theoretical analysis of the buckling resistance and experimental verification of the objective buckling resistance of compression members in connection with the actual behaviour of the structural member and corresponding relevant failure mechanism. Within the framework of the buckling resistance analysis two basic cross-section types of columns have been investigated: (i) open IPE cross-sections and (ii) circular tubes, both steel members and steel-concrete members. The attention was paid mainly to the following significant problems: the efficiency of the usage of high-strength materials in steel and steel-concrete members subjected to compression; the effectiveness of concrete contribution to the buckling resistance of steel-concrete members in comparison with steel members; the evaluation of the test results aimed to determine the design buckling resistance. This paper presents namely the results of the verification of the buckling resistance of circular tubes filled by high-strength concrete with accent to the actual contribution of concrete and to the influence of concrete properties, concrete strength and elasticity modulus.
