Useful Program Features
Dlubal Software programs and add-on modules include a wide range of powerful features.
Since our software is subject to continuous development, we are constantly adding new features. In doing so, we also take account of our customers' wishes.
Why Dlubal Software?
Export of Reinforcement RFEM - RevitSurface reinforcements defined in the RF-CONCRETE Surfaces add-on module can be exported as reinforcement objects to Revit by using the direct interface.
Automatic Determination of Number of Load IncrementsIf the check box "Number of load increments" is deactivated, the number of load increments will be determined automatically in RFEM to solve nonlinear tasks efficiently. The method used is based on a heuristic algorithm.
Adaptive Mesh RefinementWith this function, it is possible to refine the FE mesh on surfaces automatically. The mesh refinement is carried out step by step. In each step, a new FE mesh according to the numeric error analysis of the previous step will be generated. The numeric error will be evaluated by means of the results on surface elements and is based on the energy formulation by Zienkiewicz-Zhu.
The error analysis is carried out for a linear static analysis. A load case (or a load combination) is selected for which the FE mesh will be generated. The FE mesh will be used for all calculations.
Member Type "Dashpot"
The member type "Dashpot" can be used for time history analyses in RFEM/RSTAB with the add-on modules RF-/DYNAM Pro - Forced Vibrations and RF-/DYNAM Pro - Nonlinear Time History. This linear viscous damping element considers forces dependent on velocity.
With regard to viscoelasticity, the member type "Dashpot" is similar to the Kelvin-Voigt model which consists of the damping element and an elastic spring (both connected in parallel).
Data exchange with Advance Steel using *.smlx files
When exchanging data with Advance Steel using *.smlx files, the interface is automatically detected. This means that *.smlx files are possible even if no version of Advance Steel is installed.
Material Library with Steels According to the Australian Standard AS/NZS 4600:2005The material database in RFEM, RSTAB and SHAPE-THIN contains steels according to the Australian standard AS/NZS 4600:2005.
Pushover AnalysisIn RFEM, it is possible to determine pushover curves (also called capacity curves) and export them to Excel.
RF-/JOINTS Timber - Timber to Timber | Input
First, it is necessary to select the joint type and the design standard.
The connected members are imported from the RFEM/RSTAB model. The module automatically checks if all geometric conditions are fulfilled.
Also the loads are imported automatically from RFEM/RSTAB. In the Geometry window, you can specify the screw parameters (diameter, length, angle, etc.).
RF-/JOINTS Timber - Timber to Timber | Results
At first, the governing joint designs are arranged in groups and displayed with the basic geometry of the joint in the first result window. In the other result windows, you can see all fundamental design details.
Dimensions and material properties important for the connection construction are displayed immediately and can be printed directly or exported to a DXF file. It is possible to visualize the connections in RF‑/JOINTS Timber - Timber to Timber or in the RFEM/RSTAB model.
All graphics can be included in the RFEM/RSTAB printout report or printed directly. Result graphics to scale provide the option of an optimal visual check right from the design phase.
