摘要
施工过程中建筑结构从几何形态、材料性质、结构体系刚度和稳定性方面不断发生变化,从不完整结构逐渐转变为完整结构。常规结构设计是一种近似的计算方法,计算虽然方便快捷,但计算结果均存在误差,施工方法不同,计算误差的大小也不同。在考虑施工过程中混凝土的材料性质变化、施工找平调整、施工顺序等因素的基础上,对环球中心的主体施工过程进行数值跟踪分析和结果比较,同时就不同施工方案对超高层建筑竖向变形差异的影响问题进行了分析。
During building construction,the structure turns from incompletion to completeness,there are many changes happened in aspects of geometry,material property,structure stiffness and stability.General design methods are approximations,which may lead variable errors according to different construction plan.Considering the effects of concrete property changing,elevation adjusting,the construction order,authors calculate the total construction process of Shanghai World Financial Center,and analyze the vertical deformation under different construction plan in detail.
