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.
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.
RF-PUNCH Pro performs the punching shear design on concentrated load application locations (column connection, nodal support and nodal load) as well as on wall ends and wall corners.
Buildings often have extensions. If the roof levels are not at the same height, this height difference (if more than 0.5 m) must additionally be considered for the snow load assumption.
In current literature, the formulas to determine internal forces and deformations manually are usually specified without considering the shear deformation. Especially in timber construction, the deformations resulting from shear force are often underestimated.
When modeling with finite elements, you sooner or later come up with the question of how two surfaces (2D elements) lying on top of each other can be modeled. Hence, both surfaces are quite often modeled in the same plane. The possible consequences of this approach and whether there are better solutions are described below.
When calculating a surface model, the internal forces are determined separately for each finite element. Since the element-by-element results usually represent a discontinuous distribution, RFEM performs a so-called smoothing of the internal forces that takes into account the influence of adjacent elements. With this method, the discontinuous distribution of internal forces is adjusted. The results evaluation is thus clearer and easier.
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.
The modeling of planar structural components such as glass panes is generally only possible in RFEM. If it is necessary to define the stiffening effect of a pane in a particular case, it can also be simulated in RSTAB.
The calculation of timber panels is carried out on simplified member or surface structures. This article describes how to determine the required stiffness.
Using the RF-TIMBER CSA module, timber beam design is possible according to the CSA O86-14 standard. Accurately calculating timber member bending resistance and adjustment factors is important for safety considerations and design. The following article will verify the factored bending moment resistance in the RFEM add-on module RF-TIMBER CSA using step-by-step analytical equations per the CSA O86-14 standard including the bending modification factors, factored bending moment resistance, and final design ratio.
