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.
SHAPE-THIN allows you to calculate section properties and stresses of any cross‑sections. If a flange or a web is weakened by bolt holes, you can consider this by using null elements. The stresses are subsequently recalculated with the reduced cross‑section values. In this case, it is necessary to pay special attention to shear stresses. By default, these are set to zero in the area of the null elements. When recalculating shear stresses with the reduced cross‑section values and without further adaptation, it turns out that the integral of the shear stresses is no longer equal to the applied shear force. The following example shows in detail how to calculate the shear stress.
Holes like for example bolt holes can be represented by zero elements in cross‑sections created in SHAPE‑THIN. The calculation of shear stresses in the zone of such an opening was improved as follows.
