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 Steel Design add-on allows you to design steel members 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 Steel Design add-on for the RFEM 6 and RSTAB 9 programs.
In this tutorial, we would like to inform you about the essential features of the RFEM program. In the first part, a model was defined and a structural analysis was carried out. The concrete design was performed in the second part. Finally, the third part deals with the design of the steel members according to EN 1993‑1‑1 with the CEN settings.
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.
In this tutorial, we would like to inform you about the essential features of the RFEM program. In the first part, a model was defined and a structural analysis was carried out. After performing the concrete design in the second part, the third part now deals with the design of steel members. AISC 360-16 is used as a standard.
The Masonry Design add-on activates special material models that have been developed for calculating masonry structures. This allows you to consider the masonry material in an FEM analysis.
In the calculation, internal forces and deformations are determined on the basis of stress-strain lines derived from the standardization. This means that the design is based on the standard.
This manual describes the Masonry Design add-on for the RFEM 6 program.
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 Geotechnical Analysis add-on allows for a finite element analysis of soil solids with the suitable material laws in RFEM 6. By integrating Geotechnical Analysis into the FEA software, the soil-structure interaction can be represented computationally completely in the overall model.
With the Geotechnical Analysis, it is possible to determine the stresses and deformations of a soil solid. The input and result evaluation are integrated in the user interface of the RFEM 6 program.
This manual describes the Geotechnical Analysis add-on for the RFEM 6 program.
The Optimization & Costs/CO2 Emission Estimation add-on consists of two parts: On the one hand, you can use it to determine an optimal parameter layout for parameterized models, based on the user-defined optimization criteria. For this purpose, the artificial intelligence technology (AI) of particle swarm optimization (PSO) is used. On the other hand, you have the option to estimate the costs and CO2 emissions of a model by specifying the unit costs and emissions for the materials used in the model.
This manual describes the features of the add-on for the programs RFEM 6 and RSTAB 9. The explanations refer to RFEM, but also apply to RSTAB.
This manual describes the modeling of a stadium roof made of membranes in RFEM 6. Since the model consists of several segments, the creation of the individual segments is shown. Each segment consists of a main structure (a column, a stiffening element, cables) and a secondary structure (a membrane).
