This paper reports axial compression test results of centrifugal concrete rilled steel tubular short column using super high strength concrete. The concrete portion of section has a vacant hole, and the concrete is cast by centrifugal spining method using super high strength concrete. If we are able to use centrifugal cast composite column, we are able to take good points that members weights light, need not require much time for mortar fill into a vacant hole and so on. But there are not many centrifugal cast composite column on researching papers. In this paper, axial compression tests on short column specimens were carried out in order that we may confirm relations between a vacant hole and structual performance. From the results of experiments, we confirm that experimantal maximum strength is higher than superposed strength, even if a section has a vacant hole and we make understand the behavior of centrifugal cast composite column.
