Behaviour of the tubular columns filled by concrete subjected to buckling compression
Original language description
The paper deals with the possibility of using high strength concrete in case of steel tubular columns filled by concrete subjected to compression. Especially the effect of the concrete strength on buckling resistance of the composite columns is investigated. The focus of the resolution is the experimental verification of working whereas the behaviour of the compressed tubes filled by high strength concrete is compared with that filled by normal strength concrete. The combination of circular tubes and high-strength concrete seems to be one of the most effective ways to use the high-strength concrete because of eliminating the lack of tensile strength. In the case of high-strength concrete the tensile strength is growing not in proportion to compressivestrength, but more slowly. This means that a large increase in compressive strength is not accompanied by a corresponding increase in tensile and shear strength in comparison with normal strength concrete.
