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.
