Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
RFEM 5 offers you the option to define an average region by clicking ‘New Average Region’ on the ‘Results’ menu. You can choose between a rectangular, circular or elliptical shape. With this tool, you can, for example, ‘smear’ singularities due to nodal loads in a desired averaged region.
In RFEM 5 and RSTAB 8, you can now create a work plane by simply selecting three points. It is no longer necessary to create a user-defined coordinate system.
RFEM 5 and RSTAB 8 now allow you to consider the roof overhang in the automatic generation of loads. To do this, use the load generator to define the corner nodes of the roof geometry including the distances of the roof. In the left part of the picture, however, the load application is done without roof overhang. With this option, it is also very easy to specify the loads for a roof overhang on the gable side.
Second order analyses may sometimes lead to error messages that can be traced back to instabilities due to failed tension members: If compression forces occur in a tension member during a calculation step, this member is no longer considered in the next iteration step. Thus, the model can become instable.
Bracing consisting of angles (L‑sections) can resist even small compression forces. If these members are not defined as member type ‘tension member’ but as ‘buckling member’, it is often possible to calculate problematic models (see picture).
In RFEM 5 and RSTAB 8, you can specify multilayer structures as loading. The figure shows an example of a floor structure. To this end, you need to define the individual layers including the thickness and density, and obtain the according surface load. The input is saved, thus allowing you to create a well‑structured library.
The last function used in the graphical input can be repeated in RFEM and RSTAB very easily: Simply press the Enter key, but you can also select the ‘Repeat’ function on the shortcut menu.
A calculation break‑off due to an instable system can have different reasons. On the one hand this can indicate a ‘real’ instability due to an overloading of the system, on the other hand the error message can result from inaccuracies in the model.
The RX‑TIMBER stand‑alone program offers you the option to optimize the lateral-torsional bracing. With this selection, the program iteratively determines the required minimum length of the lateral-torsional bracing.
In RFEM 5 and RSTAB 8, you can design foundations according to EN 1992‑1‑1 and EN 1997‑1 in the RF‑/FOUNDATION Pro add‑on module. The following types of foundations are available:
- Bucket foundation with smooth bucket sides
- Bucket foundation with rough bucket sides
- Foundation plate
- Block foundation with rough bucket sides
In practice, these types of foundations cover a great number of design purposes.
