Original Abstract

Results presented in this paper are based on the research programme dealing with use of higher strength materials for columns made of steel circular tubes filled with concrete. Benefits of the combination of steel tube and a concrete infill are reflected in convenient load response, better fire resistance and also in constructional solution. Increasing in material strength is consequent upon effort of minimization material consumption and it is also discussed in case of concrete filled steel tubes. First, the paper deals with evaluation the experimental analysis results and their comparison with expected values determined by a standard calculation algorithm. The second part is focused on monitoring the influence of concrete material characteristics on column buckling resistance. The aim of the paper is a verification of theoretical method of determination buckling resistance and an appraisal of efficiency higher strength concrete in these types of composite members. It can be stated based on the result presented in this paper, that buckling resistance of slender column from concrete filled steel tube is influenced more by modulus of elasticity than by concrete compression strength. The use of higher strength concrete is irrelevant if the modulus of elasticity does not increase at the same time.
