The Mechanics Analysis and Research of Multi-Suspension-Centers Integral Lifting Technology for Long-Span Steel Roof

Abstract:

In construction of the steel roof a computer-controlled lifting construction technology was adopted. It differed from other similar projects in some points. First, the steel roof had large area, long-span and huge weight; next, the structure form in lifting process differed from the design status; at last, the deformation of steel roof in lifting process could not been ignored. If these characteristics could not been considered in lifting process, it maybe bring large project accident. So in this article the finite element model of the structure in the lifting status had been rebuilt. Considering the displacement difference the lifting process had been analyzed. By the analysis the influence of the displacement difference of the lifting points could be found out. Comparing with the value of the construction measure the finite element model could be validated and corrected. The conclusions of research could be used by the similar construction.
