Abstract:The features and structural layout of the project were described. Two softwares were applied to calculate the elastic response spectra of tower F for comparison, both elastic time history analysis and nonlinear static analysis were complemented. The results show that the structure can realize seismic performance objectives and meet the requirements of multiple anti seismic systems. The MIDAS Gen software was used to simulate the construction loading process of tower F, and the vertical deformation and difference between the outer frame and the core tube were calculated with  considering the shrinkage and creep of concrete during construction. The simulation results were compared with the results of one-time loading and construction simulation results without considering the shrinkage and creep. Suggestion was given to the design of the horizontal components in accordance with the engineering practice.

Keywords:super high-rise structure; dynamic elastoplastic analysis; vertical deformation; shrinkage; creep; construction simulation
