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?
Member Hinge Nonlinearity "Scaffolding Diagram"
The member hinge nonlinearities "Scaffolding - N phiy phiz" and "Scaffolding Diagram" enable the mechanical simulation of a tube joint with an inner stub between two member elements.
The equivalent model transfers the bending moment via the overpressed outer pipe and after positive locking additionally via the inner stub, depending on the compression state at the member end.
Calculation of stiffened buckling panels according to EN 1993-1-5, 4.5In SHAPE-THIN 8, the effective cross-section of stiffened buckling panels can be calculated according to EN 1993-1-5, Cl. 4.5. The critical buckling stress is calculated according to EN 1993-1-5, Annex A.1 for buckling panels with at least 3 longitudinal stiffeners or according to EN 1993-1-5, Annex A.2 for buckling panels with one or two stiffeners in the compression zone. The design for torsional buckling safety is also performed.
Conversion of Lehr's Damping into Rayleigh Damping
Calculation in consideration of a damping (Lehr's damping as well) is not possible in the direct time step integrations. Instead, the Rayleigh damping coefficients are specified by the user.
In technical literature, the given damping for specific construction forms is in many cases only a rough approximation of the real damping ratios. In RF-/DYNAM Pro - Forced Vibrations, it is possible to use the damping value to determine the Rayleigh damping. This may occur at one or two natural angular frequencies defined by the user.
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.
