依据欧洲规范 EC2关于混凝土弹性模型、收缩、徐变随时间变化规定，考虑施工顺序加载、竖向构件压应力差异、伸臂桁架后连接、下料长度调整等因素，结合某超高层建筑结构，实现了施工全过程模拟，获得各施工阶段外框架柱和核心筒剪力墙的竖向变形量及差异，对施工过程中关键构件的承载力进行验算，同时比较了后连接方案对水平伸臂桁架内力的影响。分析结果表明：在超高层设计时必须考虑混凝土收缩徐变等非荷载作用下的变形，竖向构件应考虑竖向变形而产生的压缩量进行预调整，采用后连接的施工措施可以减小水平伸臂桁架的内力。

According to European code EC2 about concrete elastic model,shrinkage and creep change over time and considering the construction order of loads,the difference of the vertical compressive stress compo-nents,cantilever truss connections and blanking length adjustment,The paper realized the whole construction process simulation in combination with a super-high building structure and obtained the results of the total ver-tical deformation and the relative deformation between the outer frame and the core-wall.At the same time,it calculated the bearing capacity of key components in every construction stages and compared the internal forces of the horizontal cantilever truss considering connection after construction.Analysis results show that concrete shrinkage and creep deformation must be considered for the design of high-rise building structure,the deforma-tion of the vertical component of vertical deformation should be considered to adjust,and the internal force of horizontal cantilever truss could be reduced through connection after construction.
