Shaoxing Zhejiang 312030 China) Abstract:During construction of the super tall posite structure building the time-dependent properties of concrete the different stress among vertical members construction loading order and the adjustment of the vertical members result in different vertical deformation.The different vertical deformation makes more difficult to control construction quality.It impacts the installation of equipment and decoration.The different vertical deformation generates additional stress in the adjacent member and nonstructural ponents which reduces the structural safety margin.Therefore it is necessary to analyze the vertical deformation of the structure during construction.Based on Tianjin Noblecenter puter simulation technique is used to analyze the vertical deformation of mega-column and core-wall according to the actual cons...
