Glass Composition Models

By defining a surface with the Glass Composition thickness type assigned, a glass composition model is automatically generated. This model is used to configure additional settings that are specifically required for glass structures.

The program tries to automatically combine surfaces with the same geometries in a model. If necessary, you can create additional models using the Creating New Material button and assign them to the corresponding surfaces.

Calculation Type

The Calculation Type defines the way the structure is calculated in RFEM.

  • 1-Phase | Full Model describes a direct calculation of the entered surface with all supports defined in RFEM.

Modeling Type

The Modeling Type determines whether the entered glass composition is to be calculated as a “surface model” or as a “solid model” (currently under development).

Shear Coupling Between Layers

For laminated glass, there is the option to consider or neglect the shear coupling between the glass layers.

Important

When modeling laminated glass to take into account shear coupling in combination with the Surface Model modeling type, note the following limitation: The ratio (G * t)/(Gf * tf) should be less than 1,000 to ensure correct results. For larger ratios, select the Solid Model modeling type.
