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.
Designing End Plate Connection of Hollow Sections Under Tension According to the CIDECT Method and by Means of the FEM Model
A site joint consisting of hollow sections with end plates will be designed. It is the bottom chord of a truss which has to be divided for transport reasons.
The deformations of the FE nodes are always the first result of an FE calculation. Based on these deformations and the stiffness of the elements, it is possible to calculate strains, internal forces, and stresses.
Result combinations exported from RF‑/DYNAM Pro - Equivalent Loads are generated by superimposing the results from the individual modal responses. For this, the SRSS rule can be used as ‘equivalent linear combination’. When result combinations are used in RF‑/STEEL there are two options available for the calculation of stresses. Either the results from the result combinations are used directly. This is done line by line for each maximum and minimum controlling internal force. Or stresses are determined from the individual load cases. The quadratic superposition rule is then performed again in RF-/STEEL.
Just like in the Display navigator of RFEM, you can set the distribution of internal forces within surfaces also in RF‑STEEL Surfaces. Since the result of the FEM calculation is always deformations, the corresponding forces will be recalculated. It means that the internal forces on a FEM element are calculated depending on the composition (triangle or square) at three or four places. In order to obtain continuous internal forces and thus a smoothed distribution, these internal forces have to be interpolated. The interpolation is possible by selecting the option ‘Distribution of internal forces’ within surfaces.
In RFEM version 5.04.xx, there is a new feature of a sophisticated graphical display of normal and shear stresses on members. It is only available for the licensed RF‑STEEL add‑on module.
The limit stresses in RF-/STEEL can be user-defined for each thickness range. To do this, click the [Edit Material] button. In the ‘Edit Material’ dialog box, you can then define the limit stresses according to yield strength or by selecting the check box ‘User-defined, independent definition of limit stresses’.
