Question:
Is it also possible to simulate an external steel structure in RWIND Simulation?
Answer:
Yes, it is; the RWIND Simulation program is designed universally and can implement any RFEM or RSTAB model.
For a steel structure consisting of pure member elements, the program creates a coherent, voluminous envelope of member surfaces for the numerical wind tunnel. The result of this modeling for the simulation depends on the available cross-sections and the mesh settings. Corresponding surface pressures result on this surface envelope due to the wind flow.
After the wind flow analysis, the program summarizes the surface pressures of the member units and gives back the corresponding equivalent load (single, uniform, or trapezoidal) for each member axis.
These loads are applied in RFEM or RSTAB for the further calculation of internal forces.
