Question
How is the coupling stiffness determined in RF‑GLASS?Answer
In RF‑GLASS, there are two different types of calculations. On the one hand, there is the "2D" calculation. In this case, a glass structure is displayed as a surface element. When considering the shear coupling, the program determines an equivalent cross-section by using the laminate theory On the other hand, there is the "3D" calculation. In this case, the composition is modeled as a solid element in the calculation, and thus the effectiveness of stiffnesses between the foil and glass is determined exactly when considering the coupling.
Further information about the calculation methods can be found in the RF‑GLASS manual, Chapter 2.

Modeling a Glass Railing | Recommendations for Input in RFEM
The architectural requirements for guard rails are still very high and railings usually require a high degree of transparency.

Increased Calculation Performance by Reducing the Nodal Degrees of Freedom
The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (e.g. trusses and membrane structures).
- Which stresses are most important for glass design consideration when using RF-GLASS?
- 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?
- Is it possible to design a spherically curved glass pane in RF‑GLASS?
- How is the coupling stiffness determined in RF‑GLASS?
- A curved pane cannot be designed in RF‑GLASS. Why?
- Is it possible to set user-defined values of the standard in RF‑GLASS?
- Are there any programs or add-on modules specially developed for glass structures?
- Which method of analysis is used for insulating glass?
