高层建筑竖向变形的施工模拟方法研究

Research on the Construction Simulation Method of the High-Rise Building's Vertical Deformation

高层建筑结构在施工过程中整体结构的刚度集成和竖向荷载的加载方式对竖向变形具有积累以及不均匀变形的影响,通过对不同施工模拟方法的竖向变形机理进行了分析,给出了与实际较为吻合的非一次性加载模式,指出了在其加载模式下竖向变形最大处为阶段施工总高度的一半,针对不均匀变形引起的损伤提出了"阶段施工补偿"的设计概念,结合深圳某超限高层建筑给出了方法的应用。

The high-rise building＇s vertical deformation has accumulated and the influence of inhomogeneous deformation,when the integration of the structure rigidity and loading ways of the vertical load in the high-rise building structure that is constructed through the vertical deformation mechanism of different construction simulation is analyzed. There is given loading mode of what is not finished for one time tallies with the actual. The maximized vertical deformation in its loading mode for half of the stage construction height is pointed out. The damage of uneven deformation＂phase construction compensation＂design concept is put forward. At the same time,the method of application that is combined with a transfinite high- rise building in Shenzhen is given.
