Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, you can simulate wind flow around simple or complex structures by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
Once you have determined the final tendon geometry in RF‑TENDON, exporting the model to a CAD program can be useful. For this purpose, the module includes the option to export the file in the .dxf file format. You can select the export function by right-clicking the workspace. After selecting the DXF format and the storage location, additional settings can be made.
In RF-/STEEL EC3, you can optimize a cross‑section automatically within the design. For this, select the corresponding cross‑section in Table 1.3 or define variable parameters for a welded cross‑section.
If you have imported a DXF file in RFEM or you need to add a membrane to an existing member structure, you can use the function "Tools" → "Generate Model - Surfaces" → "Surfaces from Cells", and thus quickly create planar surfaces.
DXF layers of ground plans cannot be directly used in FEA programs because there are only outer contours of elements (walls, ceilings, etc.) available in the drawing. However, the structural analysis program requires system axes.
The ISM file (ISM = Integrated Structural Modeling) in RFEM and RSTAB is an interesting possibility to exchange data. If you export a model to this data format, you can view and analyze it with the free ISM viewer from Bentley.
"Good tool, half the job": This proverb could equally be applied to the software industry. The better a program is task-tailored, the more efficiently tasks can be solved. The variety and complexity of today's problems, especially in structural engineering, require specifically tailored solutions. Creating your own programs by means of textual programming requires in-depth knowledge and a great ability to abstract. Understandably, only very few engineering offices face this challenge. For this reason, there are additional software solutions providing the user with a visual development environment.
For some structures, it is necessary to design them 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 models with just one mouse click is a considerable relief.
Structures are naturally three-dimensional. However, because in the past, it was not possible to easily perform calculations on three-dimensional models, the structures were simplified and broken down into planar subsystems. With the increasing performance of computers and related software, it is often possible to do without these simplifications.
Digital trends, such as Building Information Modeling (BIM) or new options for creating realistic visualized models, reinforce this trend. But do 3D models really have an advantage or are we just following a trend? The following presents some arguments for working in 3D models.
The construction industry is increasingly digitized. Structural engineers, a smaller group in the construction industry, are not always considered as engineers who immediately join the latest trends. Often for good reason. Many consider this to be the reason why topics such as utilizing the BIM method are not yet the standard in structural engineering. However, the past few years have shown that a process of rethinking has begun and new digital trends are picked up and applied.
In RFEM and RSTAB, you can use many interfaces to simplify the modeling of your structure. From background layers to the import of IFC objects that can be converted into members or surfaces, up to the import of the entire structural system from Revit or Tekla. Regardless of the performance of the selected interface, the further utilization also depends on the accuracy of the imported data.
