Wind Simulation & Wind Load Generation
With the stand -alone program RWIND Simulation, you can simulate wind flows 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.
You can make various settings in order to achieve a clearly‑arranged display of the result values. For example, some users may not want the white background in text bubbles. You can adjust the background in ‘Display Properties’ using the option Transparent and Background color.
In RF-/FOUNDATION Pro, the user can freely select the proportion of the relieving soil pressure by means of the factor kred.
For solids, there is another option for the FE mesh setting. It is possible to arrange a layered FE mesh in addition to a holistic FE mesh refinement. For this option, you can perform a defined division of the solid with finite elements between two parallel surfaces. This option is particularly suited for very large solid geometries with a small height.
For the design of concrete surfaces, the rib component of the internal forces can be neglected for the ULS calculation and for the analytical method of SLS calculation, because this component is already considered in the member design. To this end, select the check box in the ‘Details’ dialog box. If no rib was defined, this function is not available.
The program RFEM5 or RSTAB8 offers a "Spring" option when defining a member under the member types.
In order to detect the governing internal forces of a plate, a checkerboard loading is commonly used. Since it is not necessary to divide the surface into individual load segments, loading is usually carried out by means of free rectangular loads. In the case of many loads, the normal load display can become somewhat confusing.
Often in RFEM, only part of and not an entire surface must be loaded. A typical case of this is soil pressure. For this purpose, there is the option of defining free surface loads. They are surface-independent and are displayed in defined coordinate dimensions in the graphic.
For relatively large or relatively small surfaces, it can happen that the automatically created result values do not fit the model: In case of large surfaces, there can be too much result values, in case of small surfaces, too few.
In RFEM 5 and RSTAB 8, it is possible to assign nonlinearities to member end releases. In addition to the nonlinearities ‘Fixed if’ and ‘Partial activity’, you can also select ‘Diagram’. If you select the ‘Diagram’ option, you have to specify the according settings for the activity of the member end release. For the individual definition points, it is necessary to specify the abscissa and ordinate values (deformations or rotations and the according internal forces) that define the release.
In RF-/FOUNDATION Pro, it is also possible to consider the concrete cover for the foundation according to EN 1992-1-1.
