New 001364 Scaffolding and Rack Structures RFEM Modeling | Structure

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.
New 001362 Steel Structures Bridges Mechanical Engineering SHAPE-THIN Calculation Eurocode 3

Calculation of stiffened buckling panels according to EN 1993-1-5, 4.5

In 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.
New 001363 Dynamic and Seismic Analysis RF-/DYNAM Pro Calculation

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.
New 001361 Concrete Structures Building Information Modeling (BIM) RFEM RF-CONCRETE Import / Export & BIM

Export of Reinforcement RFEM - Revit

Surface reinforcements defined in the RF-CONCRETE Surfaces add-on module can be exported as reinforcement objects to Revit by using the direct interface.
New 001360 Finite Element Analysis RFEM Calculation

Automatic Determination of Number of Load Increments

If 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.
New 001359 Finite Element Analysis RFEM Calculation

Adaptive Mesh Refinement

With 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.
New 001354 Dynamic and Seismic Analysis RFEM RSTAB RF-/DYNAM Pro Modeling | Structure

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).
New 001355 Building Information Modeling (BIM) RFEM RSTAB Import / Export & BIM

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.
