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 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 Figure).
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. Alternatively, you can 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.
In most models of reinforced concrete buildings, ribs are modeled, and then the analysis is carried out on the T‑beam. If you then also design the plates, the required reinforcement within the effective plate width of the ribs is redetermined.
The selected increment of the load positions automatically increases the generated load combinations. To avoid documenting all input data of all combinations, CRANEWAY 8 allows you to output them selectively. You can find this option in the selection of the printout report. Another way for detailing the output of the load combinations is to select the shown intermediate results, which can be, for example, displayed in the long or short form or without intermediate results.
