The RF-STABILITY add-on module determines any critical load factors, effective lengths, and eigenvectors of RFEM models. Stability analyses can be carried out by various eigenvalue methods, the advantages of which depend on the structural system as well as computer configurations.
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.
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.
It is necessary to design some structures in different configurations. It may be that an aerial work platform must be analyzed in its position on the ground as well as in the middle and in the extended position. Since such tasks require the creation of several models, which are almost identical, updating all the models with just one mouse click is a considerable relief.
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.
The network-capable Project Manager controls the projects of all Dlubal Software applications in one central location. A table displays the important information for each model and corresponding file. Now, you can set dimension and weight units in the program options.
The integrated project manager helps you to organize design files of Dlubal Software programs. For this, a link is created between an existing project folder on the hard drive and the Project Manager. If you want to delete a project created in the Project Manager, there are two methods.
