Abstract:
Firstly, some basic rules of removing temporary supports from steel structural roof were presented and two basic procedures of removing temporary supports, one is supports lowering simultaneously and the other is group by group and step by step, were also discussed in detail. Secondly, three calculation methods for numerical simulation analysis of removing temporary supports which are support displacement method, equivalent rod bottom-end displacement method and jack element method were introduced. Finally, the process of removing temporary supports was simulated by ANSYS finite element software package for two examples, namely three points support cantilever beam and national stadium. The comparisons of calculation results obtained by using three points support analysis methods mentioned above indicate that equivalent rod bottom-end displacement method and jack element method are rational and effective for an accurate simulation analysis of removing temporary supports to steel structural roof.
