摘　　要：对高层混合结构施工期混凝土考虑时变因素的竖向变形计算方法进行分析,阐述混凝土收缩徐变的应力-应变关系以及混凝土徐变按龄期的有效模量法。结合保利文化广场具体的工程实例,研究了施工阶段混凝土收缩徐变对高层混合结构竖向变形的影响。High-rise mixed structure of concrete considering time-varying factors of vertical deformation during the construction calculation methods are analyzed. The stress-strain relationship of concrete shrinkage and creep and the ef- fective modulus method about concrete creep according to the age are expounded. Take the Poly cultural building spe- cific, the influence of concrete shrinkage and creep to high-rise mixed structure vertical deformation during the con- struction are discussed.
