Abstract:
In order to solve the technical difficulty problems in unloading process of the large cantilever structure, finite element analysis software ANSYS was adopted to simulate the unloading process for large cantilever structure of Chongqing Grand Theatre. According to the analytical results, the reasonable order of temporary supports removal was confirmed, and double-control guideline which regarded the deformation control as the main one and regarded the force control as the secondary one was adopted. Finally, the data measured values in the field were compared with the theoretical results, which determined the use of step-by-step approach in construction and ensured that the deformation and forces of the structure in the unloading process remained in the scope of security. The analytical results show that the theoretical model proposed in the paper can preferably simulate the large cantilever structure.
