The Best Structural Modeling Program
"We are dealing with Structural and Seismic Engineering since 1998. Dlubal Software is, in our experience, the best structural modeling program on the market. We recommend it to all those who need to deal with special and daily cases."

“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!”

Select any of the useful auxiliary functions and tools that make the modeling easier for you. This facilitates the generation of snow and wind loads, for example. Furthermore, you can consider member and hinge nonlinearities (yielding, tearing, slippage, and so on), as well as couplings or member eccentricities.
1
Cross-Section and Material Libraries Including Favorites
Discover the extensive cross-section and material libraries. They facilitate you the modeling of plate and beam structures. You can filter these databases and expand them with user-defined entries. You can also easily import and analyze special cross-sections from RSECTION.
2
Easy Creation of Views and Visibilities
A clear display is a prerequisite for your efficient and fast work with the program. Select user-defined views from different angles to facilitate the result evaluation. Using "visibilities", you can also 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.
3
Easy Model Input
There are many options available for simple input and modeling. Your model is entered as a 1D, 2D, or 3D model. Member types such as beams, trusses, or tension members, facilitate you the definition of member properties. In order to model surfaces, RFEM provides you with 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).
4
Optional Parametric Input
Do you want to efficiently process recurring systems? Then the parameterized input is recommended to you. You can create your models by using particular parameters and adjust them to a new situation by modifying the parameters.
5
Member and Support Nonlinearities
If you are working with nonlinearities, this feature is suited very well to support you. For example, you can specify nonlinearities of member end releases (yielding, tearing, slippage, and so on) and supports (including friction). Furthermore, you can use special dialog boxes to determine the spring stiffnesses of columns and walls based on the geometry specifications.
6
Variable Member and Surface Properties
Planning with members is also facilitated in the programs due to specific features. You can arrange members eccentrically, support them by elastic foundations, or define them as rigid links. Member sets allow you to easily apply the load on several members.
In RFEM, you can also define eccentricities of surfaces. Here, you can transform nodal and linear loads into surface loads. If necessary, divide surfaces into surface components and members into surfaces.
7
Generation of Wind and Snow Loads According to Eurocode
Do you want your structures to remain upright even in wind and snow? Then rely on the load wizards for plate and frame structures. You can now generate wind loads according to EN 1991‑1‑4 and snow loads according to EN 1991‑1‑3 (as well as other international standards). The load cases are generated depending on the roof shape.
8
Optional Automatic Renumbering of Objects
This feature helps you stay flexible in your planning. You can subsequently adjust the numbering of structural objects, such as nodes and members. In this case, it is possible to renumber the objects automatically in accordance with the selected priorities (axis directions).
9
Simple Model Check
Always keep track of your model. The model check quickly detects for you the input errors, such as overlapping members or identical nodes. You can automatically connect intersecting members during your input. Members can also be extended or divided graphically. The measure function allows you to determine lengths and angles of members and surfaces (only RFEM).
10
Various Load Types
If you work with loads, find a selection of useful features here. Various load types are available to you for member and surface loads (force, moment, temperature, precamber, and so on). You can assign mmber loads to members, member sets, and member lists. In the case of imperfections, inclination and precamber can be determined precisely according to the Eurocode, the American standard ANSI/AISC 360, the Canadian standard CSA S16, and so on.
11
Guidelines for Grid View of Building
Create guidelines with or without a description for the display of a building grid! You can lock the guideline position to prevent accidental moving of them, for example.
Furthermore, you can glue the guidelines to nodes in order to move the glued nodes as well. That makes your work a lot easier!

Special Solutions
First, the two-part Optimization & Costs / CO2 Emission Estimation add-on finds suitable parameters for parameterized models and blocks via the artificial intelligence (AI) technique of particle swarm optimization (PSO) for compliance with common optimization criteria. Second, this add-on estimates the model costs or CO2 emissions by specifying unit costs or emissions per material definition for the structural model.

Dynamic Analysis
Earthquakes may have a significant impact on the deformation behavior of buildings. A pushover analysis allows you to analyze the deformation behavior of buildings and compare them with seismic actions. Using the Pushover add-on, you can analyze the seismic actions on a particular building and thus assess whether the building can withstand the earthquake.
