When using a welded profile, weld seam verification can also be carried out in RF-/STEEL EC3 as part of the design. The program performs the typical designs according to EN 1993‑1‑8.
Extensive calculations may result in vast amounts of data. Of course, current hard drives and SSDs are measured in terabytes. Therefore, you expect this to be no problem for current computing technology. This is true, in fact, but as often happens, the devil is in the details.
A network dongle is the appropriate solution to ensure security for licensing within companies working with several RFEM and/or RSTAB licenses. First, the dongle is placed on a central server. The licenses are then requested by RFEM and RSTAB, as well as all other stand-alone programs, from this dongle via the network.
Project data are no longer stored in large shelves, but on secure servers. Each file gets a date stamp, which shows when the file was created, modified, and opened.
In RFEM, you have the option to create and analyze cables using sheaves. For this, use the "Cable on Pulleys" member type. It is ideal for pulley systems, where the longitudinal forces are transferred via sheaves.
As requested by many customers, the nodes are now represented by cubes after export using the direct interface to AutoCAD or in a DXF file. If you want to reuse the AutoCAD data in RFEM or RSTAB, make sure not to import all the layers when specifying the settings for the import.
In CRANEWAY, the welds between the flanges and the web of a cross‑section are dimensioned. Options are available for defining the weld as a double fillet weld or a butt weld.
"Distribution of load" represents a load actually applied to the system of FE mesh points or FE surfaces. The FE mesh size plays an important role in the loading in the case of line loads and free loads in particular.
Sometimes, a detailed examination is needed of problematic areas of a joint or the stiffness of a frame joint. The following tips can help you with this. As an example, a frame joint was modeled using RF‑FRAME‑JOINT Pro and members, and used as a basis.
A modell check allows you to find overlapping members, among other things. However, this targeted selection could cause some minor problems. Therefore, there is a selection window now available, which appears when you click on one of the elements. This appears by clicking on one of the elements. Additional information helps you to select the correct member.
User-defined views are a very useful tool for effective modeling, as the previously selected and adapted objects appear directly with a click of the mouse. These objects can also be used easily to create informative and clearly arranged result graphics. With just a few clicks, you can create all result graphics at once using the mass print function.
In RFEM and RSTAB, you can create a combination scheme in the combinatorics of load cases and combinations. This scheme can be used for other projects by transferring it to other computers using the Export/Import function. Thus, multiple people working on a project can use the same scheme.
The local coordinate system of a member is particularly important when defining member end releases and member nonlinearities. The definitions follow the orientation of the axes. You can temporarily adjust the visibility of these member axes by means of preselection.
When defining real support conditions, it is always necessary to combine linear and nonlinear support conditions. This way, a beam resting on a wall can transfer compression forces to the wall and the line support (wall) will not take over the lifting forces. These forces should be carried by screws, for example, which are defined as a linear nodal support.
In RFEM and RSTAB, you can now rotate nodal loads or apply them on member axes. Thus, inclined members can also be loaded with nodal loads perpendicularly or along the member axis.
RFEM version 5.04.xx includes an adjustment when printing graphics in the printout report. In order to display graphics in the printout report, you have to select the respective check boxes in the Global Selection tab of the Printout Report Selection window (see the figure). Checking the boxes unlocks the corresponding tabs for the tables. where you can select the tables to be displayed.
In order to also consider loading when copying, mirroring, or rotating, the corresponding option must be activated. To do this, select the corresponding check box in the "Detail Settings for Move/Rotate/Mirror" dialog box. Then, loading is included when copying until you deactivate this function.
In RFEM and RSTAB, you can create nodes not only by means of coordinates, but also by means of existing nodes. You can use the "Node Between Two Points" function to create a node located on an imaginary line connecting two nodes. You can enter the distance as a percentage or according to the relative lengths.
