- Abstract:
- According to the unreasonableness of adhesive thickness calculation formula of silicone structural sealant for hidden frame supported glass curtain walls in Technical Code for Glass Curtain Wall Engineering (JGJ 102—2003), based on experimental research, the deformation mechanism of silicone structural sealant for hidden frame supported glass curtain walls under lateral displacement of main structure was revealed by finite element analysis and theoretical derivation. The corrected adhesive thickness calculation formula of silicone structural sealant for hidden frame supported glass curtain walls was presented. The results show that glass panel is drived to rotate by silicone structural sealant under lateral displacement of main structure, and silicone structural sealant takes only a small part of the lateral displacement of main structure. The suggested value of reduction coefficient for shear displacement of silicone structural sealant is between 0.45-0.50. The obtained conclusion will play important role in design and performance evaluation of silicone structural sealant for hidden frame supported glass curtain walls in China.
