The advantage of the RFEM 6 Steel Joints add-on is that you can analyze steel connections using an FE model for which the modeling runs fully automatically in the background. The input of the steel joint components that control the modeling can be done by defining the components manually, or by using the available templates in the library. The latter method is included in a previous Knowledge Base article titled “Defining Steel Joint Components Using the Library". The definition of parameters for the design of steel joints is the topic of the Knowledge Base article “Designing Steel Joints in RFEM 6".
You can use the Steel Joints add-on in RFEM 6 to create and analyze steel connections using an FE model. You can control the modeling of the connections via a simple and familiar input of components. Steel joint components can be defined manually, or by using the available templates in the library. The former method is included in a previous Knowledge Base article titled “A Novel Approach to Designing Steel Joints in RFEM 6". This article will focus on the latter method; that is, it will show you how to define steel joint components using the available templates in the program’s library.
All data in RFEM 6 can be documented in a multilingual printout report. The design of the printout report is modern and has been highly optimized with respect to the previous (RFEM 5) generation of the program. Some of its most significant features are discussed in this article.
You can use the selection options in the printout report to receive the detail results (in short or long form) to illustrate the individual buckling modes with the relevant buckling analysis.
In RFEM 5 as well as RSTAB 8 in RF-/FOUNDATION Pro, you can save the foundation dimensions for all five foundation types as foundation templates in a user-defined database and use them later in other models.
RFEM and RSTAB save the input data, the FE mesh, the results, the printout reports, and the 3D gITF model preview, including all visual objects, in one file.
It often happens that loads should be copied as a template into another load case, for example. This article describes two ways to copy loads between load cases.
The SHAPE‑THIN and SHAPE‑MASSIVE cross-section programs are suitable for determining the cross-section properties of common thin-walled or thick-walled sections. These cross-section properties are also available for further analyses in RSTAB and RFEM.
The results of an FEM calculation are usually documented by means of isobands and isolines in the graphical display of results. In the following, we will look at creating the results graphic for the black-and-white printout.
In RFEM, RSTAB, and SHAPE-THIN, you can create user-defined print templates ("Printout Report Template") and printout headers ("Report Headers"). These templates can also be transferred to other computers and used there.
You can assign comments to each element in RFEM and RSTAB (structure element, load element, and so on). This can help to improve the overview and documentation of structures, as the comments appear in the printout report and, for example, certain objects can be filtered and displayed using the "Select Special" function.
User-defined visibilities facilitate program handling. Once created, any model groups can be quickly hidden or shown. This facilitates, among other things, the analysis of the results in larger 3D structures, as well as the creation of the report. When changing the geometry, the existing visibilities may have to be updated.
A PDF version of the printout report can be created in two ways. The most common way is to use a PDF printer that must be previously installed. The printer will be controlled like a real printer.
The name of the project/model from the General Data is shown in the header of the printout report by default. In RFEM 5 and RSTAB 8, the model name can be changed manually in the printout report independently of the actual name.
RFEM, RSTAB, and SHAPE-THIN are localized in eleven languages. All languages are available at no extra charge. The language of the program interface can be defined in the menu "Options" → "Program Options".
RFEM offers different options for the graphical display of results that have been determined in RF-CONCRETE Surfaces. This article gives an overview of these options.
