Structurally effective facing shell and core layer

Loadbearing behavior of slender sandwich walls ­subjected to vertical loading –

Sandwich walls and core-insulated double walls with increasingly thick thermal insulation layer are widely used in building practice. They enable cost-effective and convincing energy-saving solutions for use in building shells.

In designing such walls, the inner shell is assumed to be a loadbearing member and the facing shell to provide weather protection. For lack of effective design models, the stabilizing effect of the facing shell, including the connections and the core layer, on the loadbearing behavior under horizontal loading is regularly not considered in structural design. But taking...
