Why Dlubal Software?
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.
In order to consider inaccuracies regarding the position of masses in a response spectrum analysis, the standard EN 1998-1 specifies rules which have to be applied in both the simplified and multi-modal response spectrum analysis. These rules describe the following general procedure: The story mass must be shifted by a certain eccentricity, which results in a torsional moment.
A welded connection of a HEA cross-section under biaxial bending with axial force will be designed. The design of welds for the given internal forces according to the simplified method (DIN EN 1993-1-8, clause 22.214.171.124) by means of SHAPE-THIN will be performed.
In SHAPE-THIN, you can import cross-section geometries that are available as contour or centroid layouts in DXF format and use them as a basis for modeling.
When designing a steel cross-section according to Eurocode 3, it is important to assign the cross-section to one of the four cross-section classes. Classes 1 and 2 allow for a plastic design, classes 3 and 4 are only for elastic design. In addition to the resistance of the cross-section, the structural component's sufficient stability has to be analyzed.
The Project Manager is installed by default when installing RFEM and RSTAB and manages all projects and calculation files. In the Project Manager, you can link different projects to have a clear overview of the program files.
In SHAPE-THIN, it is possible to perform the calculation of stiffened buckling panels according to Section 4.5 of EN 1993-1-5. For stiffened buckling panels, the effective surfaces due to local buckling of the single panels in the plate and in the stiffeners as well as the effective surfaces from the entire panel buckling of the stiffened entire panel have to be considered.
The stand-alone program SHAPE‑THIN determines characteristic values and stresses of any thin‑walled cross‑sections. Graphic tools and features allow for modelling complex cross‑section shapes. In addition to the graphical input, it is also possible to enter the data in tables. As an alternative, you can import a DXF file and use it as a basis for further modelling. Also, each cross‑section can be entered using the cross‑section library of Dlubal Software and combined as a part with the user-defined elements.
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.
Buildings must be designed and dimensioned in such a way that both vertical and horizontal loads are conducted safely and without large deformations in the building. Examples of horizontal loads are wind, unintentional inclination, earthquakes, or a blast.
