The Stress-Strain Analysis add-on performs a general stress analysis by calculating the existing stresses and comparing them with the limit stresses. Strains for surfaces and solids can also be determined.
During the stress analysis, the maximum stresses of solids, surfaces, and line welds (RFEM only), as well as members are determined. The governing internal forces are also documented for each member and each surface. Furthermore, there is the option of an automatic section or thickness optimization including the update of the sections or surface thicknesses modified in RFEM/RSTAB.
This manual describes the Stress-Strain Analysis add-on for the programs RFEM 6 and RSTAB 9.
The Concrete Design add-on allows you to design reinforced concrete members and surfaces according to various design standards. It is possible to perform the ultimate limit state and serviceability limit state design checks. The input and result evaluation are completely integrated in the user interface of the structural FEA software RFEM and the frame & truss analysis software RSTAB.
This manual describes the Concrete Design add-on for RFEM 6 and RSTAB 9. In RSTAB, you can only design members and member sets, not surfaces.
The Timber Design add-on allows you to design timber members and surfaces according to various design standards. Cross-section resistance checks, stability analyses, and serviceability limit state design checks can also be performed. The input and result evaluation are completely integrated in the user interface of the structural FEA software RFEM and the frame & truss analysis software RSTAB.
This manual describes the Timber Design add-on for the RFEM 6 and RSTAB 9 programs.
Dynamic analyses in RFEM 6 and RSTAB 9 can be performed in several add-ons.
- The Modal Analysis add-on is the basic add-on, performing natural vibration analyses for member, surface, and solid models. It is a prerequisite for all other dynamic add-ons.
- The Response Spectrum Analysis add-on allows you to perform a seismic analysis using the multi-modal response spectrum analysis.
- The Time History Analysis add-on allows for a dynamic structural analysis of external excitations that can be defined as a function of time.
- The Pushover Analysis add-on allows you to determine the maximum nonlinear response of a structure to seismic loads.
- The Harmonic Response Analysis add-on is still under development.
This manual describes the dynamic analysis add-ons for RFEM 6 and RSTAB 9.
The Form-Finding add-on finds the optimal shape of members subjected to axial forces and tension-loaded surface models. The shape is determined by the equilibrium between the member axial force or the membrane stress and the existing boundary conditions.
The resulting new model shape with impressed force conditions is made available as a universally applicable initial state for further calculation of the entire structure.
The Multilayer Surfaces Add-on allows you to define the layer structure of any material models. In the case of orthotropic materials, the individual layers can be rotated by an angle β, and thus it is possible to consider different stiffnesses by direction. The Multilayer Surfaces add-on is completely integrated in the user interface of the FEA program RFEM.
This manual describes the Multilayer Surfaces add-on for the RFEM 6 program.
RWIND 2 is a program (digital wind tunnel) for the numerical simulation of wind flows around any building geometries with determination of the wind loads on their surfaces. RWIND 2 is available as a Basic and Pro version.
RWIND 2 can be used as a stand-alone application or together with RFEM and RSTAB for a complete structural analysis and design.
The RFEM add-on module RF-CONCRETE Members allows for ultimate and serviceability limit state designs of reinforced concrete members according to various standards. Optional wird überprüft, ob der Brandschutznachweis nach EN 1991-1-2 erfüllt ist.
Im Handbuch ist auch die Modulerweiterung RF-BETON NL beschrieben.
The RFEM add-on module RF-CONCRETE Surfaces allows for ultimate and serviceability limit state designs of reinforced concrete surfaces according to various standards. Dabei werden auch die zulässigen Höchst- und Mindestbewehrungsgrade für die verschiedenen Bauteiltypen sowie eine benutzerdefinierte Grundbewehrung berücksichtigt.
Im Handbuch sind auch die Modulerweiterungen RF-BETON Deflect und RF-BETON NL beschrieben.
The RFEM add-on module RF-MOVE Surfaces generates load cases from different positions of moving loads, such as for example, vehicles on bridges.
In addition, you can generate an enveloping result combination.
