- Combination of various, also nonlinear, material models in a layer structure
- Graphical display of layers in a surface in the RFEM interface
- Fast calculation on a surface stiffness matrix in RFEM, a subsequent distribution of stresses to the individual layers
Multilayer Surfaces (such as Laminate, CLT) for RFEM 6
Definition of Multilayer Surfaces, such as Laminate Surfaces or Cross-Laminated Timber (CLT)
Advantages
The Multi-Layer Surfaces add-on allows you to define multilayer surface structures. A flexible composition of layers (using surface releases) as well as a coupling of solid elements consisting of gas, for example, is possible with minimum effort (currently under development).
You create a local overall stiffness matrix from a user-defined layer structure. This add-on is suitable, for example, for the definition of cross-laminated timber elements, textile reinforced concrete, insulating glass panes, fiber-reinforced plastic, and so on. The design is carried out in the add-ons, such as Timber Design.
An extensive library of manufacturer-specific superstructures made of cross-laminated timber facilitates the definition of cross-laminated timber.

Features
- Flexible definition of different layer compositions
- High efficiency due to few entries required
- Flexibility due to detailed setting options for basis and extent of calculations
- Generation of a local overall stiffness matrix of the surface in RFEM, based on the selected material model and the layers contained
- Graphical display of the orientation of the individual layers

Procedure
Please note that all data specified in the Multilayer Surfaces add-on regarding materials, load combinations, and result combinations must comply with the design concept of the standard. The material library already contains the relevant materials. RFEM allows you to automatically generate the load and result combinations in accordance with the standard. If you want, you can also create these combinations manually.
You can vary the structure of layers forming the basis for the stiffness calculation. Furthermore, you can adjust the parameters defined by the selected material model according to your individual needs. This way, completely free selection is provided to you when generating the stiffnesses.
The selected material also determines the limit stresses of each layer. You can also adjust these values according to your needs. In this case, the composition of layers is assigned to any surface as a thickness type.

Results
The stiffnesses contain all design check formulas, including standard references, so you can precisely follow the design checks.
In this case, all input and result data are part of the RFEM printout report. You can select the report contents and extent specifically for the individual design checks. In the end, you have thus exactly what you wanted.
