Abstract: A TOD business district office building is composed of a large chassis basement， upper multi￣storey commercialbuilding and three high￣rise office buildings. Three structure cracks were set out of the ground to separate the tower from thepodium. Taking tower A as an example for scheme comparison， the analysis results show that concrete filled steel tube(CFST) frame￣concrete core tube structure can effectively increase the clear height space in the office area， reduce the sizeof frame column， improve the assembly rate， and shorten the construction period and construction cost is controllable and itis suitable for this kind of high￣rise office building. The corridor between the two towers of A、B is placed on the roof bysliding at both end. The lead rubber bearing was adopted. The relative displacement between the corridor and the lowertower under various working conditions was calculated and analyzed. The analysis results show that the relative displacementbetween the corridor and the main building does not exceed the allowable bearing slip under the rare earthquake， and thebearing slip is in a small range under the action of wind load. The members layout of the connecting bridge structure ofsuspension￣cable roof between the north and south blocks was introduced， and the change of cable force under typicalworking condition was analyzed. The analysis results show that the control cable length should be the main factor and cableforce should be the auxiliary factor in sling construction.

Keywords:CFST frame￣concrete core tube； lead rubber bearing； connected structure； sliding connection； suspended￣cable structure
