Abstract: The CFST beam string structure, which is made up of CFST beam and steel cable is well used in the civil engineering. The excellent mechanical behavior comes from the full application of the constituent members. The design procedure was discussed in this paper by a living project. Based on the analysis results, the main issues in the design and construction were studied, such as structure style choice, joint design, concrete casting and so on. Finally some good proposal was achived.
Keywords: the beam string structure;  concrete filled steel tube( CFST);  joint,  concrete casting
