Structural Silicone Glazing - Design & Modelling

The use of Structural silicone glazing (SSG) systems in large commercial glazed facades is well established in current practice, mainly due to the architectural aspiration of having a continuous smooth glass surface across the building elevation. Enhanced thermal and security (blast) performance are...

SSG façade systems are structurally complex due to the fact that multiple load-paths can be identified within the system.
