【提要】 超高层建筑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。通过建立整体钢平台模板体系和建筑结构共同工作的分析模型，考虑建筑结构刚度的不确定性，以矩阵摄动理论为基础，采用改进的区间分析法求解整个体系的频率和振型，相关结果可以指导模板体系的设计。

Abstract:The integral steel platform formwork system of superhigh buildings is adopted
to bear great dynamic loads,and it is indispensable to analyze the dynamic character
istics of it to ensure the safety.The model of formwork and structure is established and the uncertain rigid of structure is considered.Based on matrix perturbation theory,the frequencies and models are obtained by improved interval analysis method.The results can be referred in design and construction of formwork system.
Keywords:superhigh building;integral steel platform formwork system;dynamic characteristic;perturbation theory
