Research on Deformation Monitoring of Large Span Hyperbolic-Paraboloid Composite Torsional Shell

Abstract:

Long span hyperbolic-paraboloid composite torsional shell is a new type structure. In order to find out actual deformation of the roof during construction, monitoring is carried out based on deformation monitoring scheme that was put forward in this paper, and deformation parameters and characteristic of the roof are obtained. It is proved that the measured deformation values are basically consistent with the simulation calculations, and the results show that the scheme is correct and feasible, meanwhile, all of monitoring results are helpful for future analog calculation, design and construction optimization of similar project.
