Abstract:Guangdong International Hotel was composed of skirt building and towers, and was reconstructed in order to meet the function requirements. The pre-stressed steel structure was adopted in large-span planting roof and a new design idea of using hinged connection before rigid connection was first proposed. A design method of damper was introduced and the mechanical problem in the second-order effect of frame column of the banquet hall was worked out. A new design idea was put forward for the problem of spandrel beam subjected to torsion. Adoption of damper reduced construction period and saved cost, and sufficient calculation and analysis could ensure the safety of the structure.

Keywords:reinforcement and reconstruction; second-order effect; hinged connection before rigid connection; pre-stressed steel structure
