Abstract:The concrete-filled rectangular steel tubular (CFRT) members are adopted as frame columns in Tower A of Dalian Victoria Square. The design and analysis method as well as joint structure contents of CFRT columns were introduced. At the same time design and structural details of CFRT columns in basement of the project were focused as well as the force transmission structure of key joints of outriggers, and the key nodes were analyzed by finite element software. Finally the construction and detection method of CFRT  were elaborated. Through theoretical analysis and engineering practice, it is proved that the CFRT column has the advantages of high bearing capacity, excellent seismic performance and convenient construction, and it has certain advantages in the super high-rise structure.

Keywords:concrete\|filled rectangular steel tube; super high\|rise structure; joint structure; outrigger
