摘　　要：随着结构体系的日益复杂,高层、超高层建筑施工过程中的问题越来越多。其中,一个关键的问题是:在整个施工过程中,不同竖向构件之间的竖向变形差给施工和结构安全带来隐患。此隐患不仅影响施工质量,而且影响整个结构体系的安全。针对此问题,以邯郸市某框架-核心筒结构为例,从竖向构件竖向变形差的计算方法选择着手,分析了不同加载方式对竖向变形差计算结果的影响。结果表明,相较一次性加载方式,精确加载是更接近实际的一种加载方式。With the increasing complexity of the structural system,there are growing issues in the construction process of high-rise and super high-rise buildings.One key issue is the vertical deformation difference between various vertical components throughout the construction process.This difference poses hidden dangers to both construction quality and the overall structural safety.To address this problem,this paper examines a frame-core tube structure in Handan city as a case study.It analyzes the impact of different loading methods on the calculation of vertical deformation differences,focusing on the selection of calculation methods for vertical components.The findings indicate that a precise loading approach is more realistic than a one-time loading method.
