Interval Analysis on Dynamic Behavior of Continuous Beam Model of Formwork System for Construction of Super High Buildings

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 characteristics 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.
