CFT(Concrete Filled steel Tube) combines the benefits of steel structure with that of concrete as a advantageous structure of
being able to exhibit the maximum performance and excels in workability, economical efficiency, with being able possible to make
high-rise building and long-span space and use widely in spite of small-section of column. However, it is difficult to inspect the
filling performance of concrete due to the closed section like circular and square CFT columns. Specially, in case of joint with
diaphragm, there is probability to occur a void in bottom of the diaphragm after placing concrete. Moreover, it is so hard to
guarantee the quality of CFT and facilitate placing of concrete that the ways are needed to control the proper degree of strength
suitable for filled-concrete in steel tubes. Due to this actual circumstances, the fact is that it is difficult for CFT to apply in the
workplace because of lack of confidence in quality control of owner and engineer of high-strength and high flow concrete and lack
of experience in a method placing in sites.
In this study, the research is focused on finding the data on methods of strength concrete for CFT while examining compactability
and workability of concrete by the mock-up test used over 800㎏f/㎠high strength concrete. Through such like this research, it is
aimed at offering required data for field application of CFT in building industry nationwide.
