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 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.
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 second part deals with the concrete design of the slabs, walls, beams, and the column according to EN 1992‑1‑1 with the CEN settings.
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. Now, the second part deals with the concrete design of slabs, walls, beams, and the column. ACI 318-19 is used as a standard.
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.
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 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 the load cases are combined within the construction stages.
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 Optimization & Costs/CO2 Emission Estimation add-on consists of two parts: On 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).
Using an example of a building ceiling, we explain how to perform reinforced concrete design according to Eurocode 2. Furthermore, the result documentation in the printout report is explained.
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.
