Structural FEA Software RFEM 6 | Modeling
Useful Tools for Fast Generation of Structures
"We are completely satisfied with RFEM and with Dlubal Software team too. Keep it up!
We are in contact with a lot of engineers and with the team of research of structural wood at the Santiago of Compostela University and always talk about RFEM like the software of reference."
“I really enjoy working with Dlubal Software programs. The structure generation and modification can proceed smoothly:
- Manageability of functions in the menu and movability in space
- Data transparency: checks, options to modify and transfer data
I am happy that I switched over to Dlubal Software!”
Useful auxiliary functions and tools for generating snow and wind loads, etc. facilitate the modeling process. Member nonlinearities (yielding, tearing, slippage, plastic hinge, etc.) are possible, as well as couplings or member and surface eccentricities.
Extensive cross‑section and material libraries facilitate the modeling of plate and beam structures. These databases can be filtered and expanded with user-defined entries. You can also import and analyze special sections from RSECTION.
User-defined views from different angles facilitate the evaluation of results. By using "visibilities", you can divide the model into user-defined and generated partial views that fulfill certain criteria. It is thus possible, for example, to only activate the surfaces of a specific material or members with a particular cross-section for the display.
Structures are entered as 1D, 2D, or 3D models. Member types such as beams, trusses, or tension members facilitate the definition of member properties. In order to model surfaces, RFEM provides various types, such as Standard, Without Thickness, Rigid, Membrane, and Load Distribution.
Furthermore, you can choose between different material models in RFEM, such as Isotropic | Linear Elastic, Orthotropic | Linear Elastic (Surfaces, Solids), or Isotropic | Timber | Linear Elastic (Members).
To efficiently manage recurring systems, the parameterizable input is a good choice. Models can be created using particular parameters and adjusted to a new situation by modifying the parameters.
You can specify nonlinearities such as yielding, friction, tearing, slippage, and so on, for member hinges and supports. There are special dialog boxes available for determining the spring stiffnesses of columns and walls based on the geometry specifications.
Members can be arranged eccentrically, supported by elastic foundations, or defined as rigid links. Member sets facilitate the load application on several members.
In RFEM, you can also define eccentricities of surfaces. Here, it is possible to transform nodal and linear loads into surface loads. You can divide surfaces into surface components and members into surfaces.
Load wizards for generating wind loads according to EN 1991-1-4 and snow loads according to EN 1991-1-3 (as well as other international standards) are available for plate and frame structures. The load cases are generated depending on the roof shape.
The numbering of structural objects such as nodes and members can be adjusted subsequently. It is possible to renumber the objects automatically in accordance with the selected priorities (directions of axes).
The model check quickly detects input errors such as overlapping members or identical nodes. You can automatically connect intersecting members during the input. Members can be extended or divided graphically. The measuring function allows you to determine the lengths and angles of members and surfaces (RFEM only).
There are various load types available for member and surface loads (force, moment, temperature, precamber, and so on). Member loads can be assigned to members, member sets, and member lists. In the case of imperfections, inclination and precamber can be determined according to ANSI/AISC 360, CSA S16, the Eurocode, and so on.
