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 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 Aluminum Design add-on allows you to design aluminum members according to various design standards. It is possible to perform cross-section resistance checks, stability analyses, 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 Aluminum Design add-on for the RFEM 6 and RSTAB 9 programs.
The "Steel Joints" add-on allows for the analysis of connections on the basis of an FE model. The design checks are carried out for various connection types for rolled and welded cross-sections. The input and result evaluation are completely integrated in the user interface of the structural FEA software RFEM.
This manual describes the Steel Joints add-on for RFEM 6.
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 in the following parts. This part now deals with the design of the steel connections according to EN 1993-1-8 with the CEN settings.
The Construction Stages Analysis (CSA) add-on allows you to represent the construction process of the model in the RFEM 6 program. In this way, you can add, remove, or adjust structural objects to the individual construction phases. Furthermore, you can use the add-on can to determine the sequence of the load application and the way how the load cases are combined within the construction stages.
For some structures, the long-term effects, such as creep, shrinkage, and aging, can influence the distribution of internal forces. This time-dependent material behavior can be determined using the Time-Dependent Analysis (TDA) add-on, which is available in the RFEM 6 program.
The influence of the time-dependent material behavior is currently only taken into account for member elements, and creep effects for the material concrete.
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 in the following parts. This part now deals with the design of the steel connections according to AISC 360-22.
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.
This manual describes the topics of the webinar "Modeling and Design of Solid Elements in RFEM 6".
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.
