| 摘 要： | 施工过程和混凝土徐变对高层建筑结构具有重要影响。本文提出采用龄期调整的有效模量法(AMME)考虑施工期混凝土徐变的影响,并利用超级有限元理论进行施工过程的模拟,并以某巨型框架作为算例进行了分析。结果表明施工过程和混凝土徐变对结构的内力和竖向变形具有重要影响,计算方法切实可行,结论可供设计施工参考。

| Abstract: | It is of important meaning to high-rise building considering concrete creep and construction process.The AMME method and the super finite element theory are proposed to consider the influence of concrete creep during construction.As an example,a structural analysis of mega frame is performed.The results indicate that the influence of construction process and concrete creep are important to the internal force and vertical deformation of structure.The calculation method is feasible,and the conclusion can be a useful reference for design and construction. |
