Interval Analysis on Dynamic Behavior of Integral Steel Platform Formwork System for Superhigh Building Construction/Luo Yanbin1，Xu Wei1，Gong Jian2，Ye Keming2(1 Structural Engineering Department,Tongji University,Shanghai 200092,China; 2 Shanghai Architectural Engineering General Co.,Shanghai 200120,China)
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
