The self-weight of the glass curtain wall has the following impacts on the building structure:

Increase structural load:

The self-weight will become an additional weight that the building structure must bear, especially in high-rise buildings. The accumulated self-weight of a large number of glass curtain walls may put higher requirements on the bearing capacity of the structure, and the structure may need to be strengthened to ensure safety.

Affect foundation design:

The larger self-weight will put greater pressure on the building foundation, thereby affecting the design parameters such as the selection, size, and burial depth of the foundation to ensure that the foundation can stably support the weight of the entire building including the glass curtain wall.

Change the distribution of structural internal forces:

It will change the internal force distribution of the building structure in the vertical and horizontal directions, which may cause stress concentration or increased deformation in certain parts, which needs to be fully considered and corresponding countermeasures taken in structural analysis and design.

Affect structural deformation:

It may cause a certain degree of vertical deformation of the building during long-term use, which requires an appropriate deformation margin to be reserved in the structural design to avoid problems such as damage or sealing failure of the glass curtain wall due to structural deformation.

Improved requirements for connection nodes:

To reliably transfer the weight of the glass curtain wall to the building structure, the connection nodes need to have sufficient strength and rigidity, otherwise, the nodes may be damaged, which will affect the safety of the entire curtain wall system.
