摘　　要：整体钢平台模板体系是适应超高层建筑主体施工需要的新型模板体系,在我国有广泛的应用前景。超高层建筑高度大、施工周期长,模板体系受动荷载影响较大,对模板体系的动力特性进行分析有利于保证其使用安全。本文通过建立整体钢平台模板体系和建筑结构共同工作的两种连续梁分析模型,考虑建筑结构刚度的不确定性,采用区间分析法求解整个体系的频率,相关结果可以指导模板体系的设计。The integral steel platform formwork system is a new kind of formwork system to adapt the construction need of super high buildings. For the great height and long construction period of super high buildings, formwork system is apt to bear great dynamic loads, so it is indispensable to analyze the dynamic characteris- tics of the formwork system to ensure its safety. In the paper, two continuous beam models of the formwork and the structure were established and the uncertain stiffness of the structure was considered. The frequencies were obtained by interval analysis method. The results can be uesd in the design of formwork systems.
