I would like to design a glass pane with temperature loads. In this case, a message appears saying that the load case includes the "temperature" surface loads types that are not transferred to the created temporary model. How can I consider the temperature loads?

Answer

The temperature loads as surface loads on general glass cross-sections cannot be considered by modeling them as solid elements in the program. With the default settings, the glass pane is modeled by using 3D solid elements.

However, the 2D calculation allows for modeling temperature loads as surface loads. You can set this in the details of the layer structure, so that the 2D calculation (plate theory) is performed. In this case, it is also possible to consider the shear coupling between the layers, if necessary.

Further details on calculating and using laminated glass can be found in the technical article "Calculation and Use of Laminated Glass."

After the successful calculation, you obtain the results for the respective layer structure. Figure 04 shows the results as an example of a layer structure without shear coupling.
