Abstract:Considering the seismic performance, architectural requirements and cost saving,concrete-filled rectangular steel tube members are adopted as frame columns and inclined column transfer structures in Huamin Imperial Tower. The analysis and connections of concrete-filled rectangular steel tube members were introduced. The design and joints of inclined column transfer structures with the member of concrete-filled rectangular steel tube were expounded. The analysis using the finite element analysis program ANSYS was carried out for the important joint. The engineering practice shows that the  using of concrete-filled rectangular steel tube members reduces the size of the columns, and it is a convenient way to connect steel beams and columns. At last, the important problems in the construction of concrete-filled rectangular steel tube were introduced.

Keywords:concrete-filled rectangular steel tube member; joint design; inclined column transfer structure; construction
