Abstract: The new CCTV headquarters consists of two towers leaning 6 off vertical in both directions, a tremendous 14 -story -high cantilever joining two leaning towers at the top and a 9 -story -high podium at the bottom. Due to the continuouslyadded gravity and additional bending moment conducted during the construction process, the variation of the structuraldeformation is very complicated. During the construction process of the structure, it may lead to a considerable deviationbetween the structural construction -completed configuration and the structural design configurationwithout taking the pre -setdeformation value (PDV) for the structural members. It will be presented a computational method to determine PDVs forthese inclined high -rise structures, i. e. stepped comprehensive iteration method. This analysismethod has been conductedand directly applied in the determination of PDVs of structural members of the new CCTV headquarters. Lots of numericalresults have been obtained and used as guidelines for the erection and construction of the new CCTV headquarters.
