This paper is related to an ongoing project for which a structural digital twin of the Kalix bridge in Sweden is being developed and implemented.
In rare cases, it may happen that an RFEM or RSTAB file cannot be opened. These files contain mostly results and report data.
In RFEM and RSTAB, you can apply various visibilities in the Views project navigator.
To work even more efficiently, RF‑GLASS allows you to create and save different, user‑defined layer structures that can be reimported later or loaded in another project.
The network-capable Project Manager controls the projects of all Dlubal Software applications in one central location.
Warning Regarding Connection to Project
---
When opening a model immediately after opening the program, there is a message window asking if you want to create a new project for the model in the Project Manager.
An individual user‑defined workspace can increase your productivity and make your daily work easier. This is why many users take the opportunity to adjust the toolbars in RFEM and RSTAB and to create their own toolbars containing the most frequently used commands.
In RFEM and RSTAB, you can work with the Project Manager. It allows you to create an entire project structure and to connect it with the folders on the local hard disk.
In RFEM 5 and RSTAB 8, it is useful to parameterize frequently occurring components with variable dimensions. In the Block Manager, you then can specify new dimensions and import them in a new or existing file.
Due to rapid development in the IT sector, including structural design, the trend is towards a global model. Large projects are rarely carried out by a single engineer. Unified project management is the key to successful work in major projects.
The same structures are often needed in several projects, such as the purlin with columns and braces in this example. The dimensions can be changed directly in RFEM or RSTAB by shifting the nodes.
The network-capable Project Manager controls the projects of all Dlubal Software applications in one central location. The projects are linked to the folders on the hard disk.
As a quick tool for changing the structure geometry, the "Line Grid" option is available in "Project Navigator – Data" under "Guide Objects".
These days, it is common practice to use structural standard templates. Thus, only the basic structure has to be adjusted to the current project.
When updating within a version series (for example, RFEM 5.01.01 to 5.01.02), the old program files are removed and replaced by new ones. The project data, of course, remain unchanged. When updating to the next version series (for example, RFEM 5.02.01), the new version is installed in parallel. The program files are located in different directories, so the previous version is still available.
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.
The Views Navigator in RFEM 5 and RSTAB 8 provides many options for setting the screen views.
When evaluating line support forces, implausible diagrams sometimes arise at first glance. In particular, for variable loads at locations that also have a nodal support, at division points and edge locations of supported lines, the results sometimes show unexpected support reactions. Using the function of the linear smooth distribution in Project Navigator – Display does not always lead to the expected result diagram.
The Project Manager is installed by default when installing RFEM and RSTAB and it manages all projects and calculation files. In the Project Manager, you can link different projects to have a clear overview of the program files.
Lattice towers represent typical applications in steel construction. Examples of this special type of truss structure are antenna and overhead line towers, as well as columns for wind power stations, cable cars, and supporting frame constructions. The modeling can be done individually in RFEM and RSTAB by entering various tower elements. Furthermore, you can use different copy functions and parameterized input options. However, this procedure normally requires considerable effort. It is more convenient to model such structures using prefabricated catalog elements provided by the Block Manager. These elements are automatically stored in the database during program installation. Thus, you can use tower segments, platforms, antenna brackets, cable ducts, and so on as parameterized building blocks for generating diverse tower structures.
