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 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 "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.
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.
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 Torsional Warping (7 DOF) add-on allows you to consider the cross-section warping as an additional degree of freedom for a global calculation of members in RFEM and RSTAB. 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 Torsional Warping (7 DOF) add-on for the programs RFEM 6 and RSTAB 9.
The Building Model add-on allows you to define and manipulate a building by means of stories. The stories can be adjusted in many ways. Information about the stories and also the entire model (a center of gravity) is displayed in tables and graphics.
This manual describes the Building Model add-on for the RFEM 6 program.
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 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).
This manual describes the topics of the webinar "Masonry Design of Using Finite Element Method in RFEM 6".
This webinar shows you how to model masonry structures in RFEM 6 and how to calculate them using the nonlinear orthotropic material model.
This manual describes the topics of the webinar "Stability and Warping Torsion Analyses in RFEM 6 and RSTAB 9".
In the webinar, a stability analysis of a staircase tower is carried out. It explains when and why a warping torsion analysis with 7 degrees of freedom is necessary. Furthermore, special attention is given to how you can create and combine local imperfections in RFEM 6 and RSTAB 9.
In the manual, all steps are carried out in RFEM 6, but the same also applies to RSTAB 9.
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.
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.
