What is the glass of Shanghai Millennium Seagull Hotel made of?

According to the specification requirements, the bearing capacity of all-glass curtain wall is checked. According to the experience, the bearing capacity and deformation capacity of stress components such as glass panel, glass rib and structural adhesive basically meet the requirements of current codes. Due to the limitation of site conditions, the ceiling removal inspection of the connecting nodes was not carried out. Considering that no deformation and damage were found during use, it is considered that they basically meet the requirements of safe use.

The glass curtain wall in the lobby and the upper suspended steel structure are post-reconstructed structures. The steel frame used to hang glass has a large span, and it is easy to bend down in the middle of the span under load, which will lead to the change of internal stress of glass curtain wall, and even lead to the explosion of glass curtain wall panels or ribs and the cracking of structural adhesive in serious cases. Due to the lack of information such as steel frame and the detection conditions for removing the suspended ceiling on site, it is impossible to carry out on-site detection and checking analysis of the structure. It is suggested that the deformation of the upper steel frame should be inspected and detected to eliminate potential safety hazards and strictly control its deformation.
