Abstract

Abstract

Four calculation methods for numerical simulation analysis of removing temporary supports from large-span steel roof were introduced——support displacement method, equivalent rod bottom-end displacement method, jack element method and jack-gap element method. Then a new method, constraint equation method, was proposed. All the methods mentioned above were used separately to analyze the process of removing temporary supports from a three-point-support beam which was fixed at both ends. The comparisons of results obtained by these methods indicate that the proposed constraint equation method is rational and effective for accurate simulation analysis of removing temporary supports to steel structural roof.
- large-span steel structure,
- simulation of removing temporary supports,
- unloading jack element,
- constraint equation method
