Abstract:
The roof of Hangzhou Century Center is a large-span overhanging steel reticulated shell withsuper-large area and unique shape. It is a very innovative structural form. The construction scheme ofground grid unit assembly and high-altitude block installation is adopted. Through the whole processconstruction analysis, the stress and deformation of the structural components are controlled, and theunloading schemes are compared and analyzed. As the foundation platform of the upper temporary supportstructure, the deformation and bearing capacity of the steel arch bridge can meet the requirements of thecode during the whole construction process, and the temporary support structure system is designed.Through the construction process monitoring, the maximum z-direction deformation of the monitoringpoints after unloading is about 16mm, and the maximum stress of the key components is about 79MPa.The monitoring results are close to the construction analysis results.
