Abstract: Tianjin tower is the landmark building of Tianjin, and is of out-of-codes super high-rise concrete filled steel tube (CFST)-steel reinforced concrete (SRC) hybrid structure. As to this type of architecture, the impact of creep on the concrete work construction cannot be ignored. Considering the complexity of creep calculation of the integral structure, the simplified creep calculation model will be adopted for the construction simulation in this paper. The comparison with the results of on-site construction monitor shows that the simplified model is reasonable and practical. Additionally the analysis on the impact of creep on CFST structure is made, providing theoretical and practical references for performance evaluation of the structure of Tianjin Tower and the selection and optimization of construction methods of Tianjin Tower.

Abstract: Tianjin Tower is the tallest building in North China. It is an out-of-code super high-rise building. Considering the special structure and safety factors during the construction, this paper describes the monitoring of the construction. The problems on numerical simulation model, creep calculation model and steel plate sheer wall welding during the construction monitoring have been discussed and corresponding solutions are given. Through the comparison and studies on the results of field monitoring, the solutions in this paper have provided practical advice on performance evaluation of the structure of Tianjin Tower and construction methods of Tianjin Tower, and are of certain significance in the reference for the construction monitoring of super high-rise buildings alike.
