The Stress-Strain Analysis add-on performs a general stress analysis by calculating the existing stresses and comparing them with the limit stresses. RFEM also determines the stress ranges. Furthermore, it is possible to determine strains for surfaces and solids.
During the stress analysis, the maximum stresses of solids, surfaces, and line welds (RFEM only), as well as of members are determined. The governing internal forces are also documented for each member and 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 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.
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.
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 carried out. Then the concrete and steel designs were performed out in the following parts. This part now guides you through the dynamic analysis of the model according to EN 1998-1 with the CEN settings.
For some structures, long-term effects such as creep, shrinkage, and aging can influence the distribution of internal forces. This time-dependent material behavior can be analyzed with the Time-Dependent Analysis (TDA) add-on, which is available in the RFEM 6 program.
The influence of the time-dependent material behavior can be analyzed for both members and surfaces. Creep effects are only taken into account for the material concrete.
First, it shows how to model a hip rafter in RFEM 6 and how to apply loads, as well as how to perform timber design according to Eurocode 5. The creation of a printout report and the use of parameters and user-defined scripts are then discussed.
In the webinar, a splice with bolts is modeled. It explains how you can define the contact between solids and perform a stress-strain analysis. Furthermore, the utilization of welds is also considered.
