Wind Simulation & Wind Load Generation
With the stand -alone program RWIND Simulation, you can simulate wind flows around simple or complex structures by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
The member boundary conditions have a decisive influence on the ideal critical moment for lateral-torsional buckling Mcr. The program uses a planar model with four degrees of freedom for the determination. The corresponding coefficients kz and kw can be defined individually for standard -compliant cross -sections. This allows you to describe the degrees of freedom that are available at both member ends due to the support conditions.
The reinforced concrete design for the fire situation is carried out according to the simplified method according to EN 1992-1-2 clause 4.2. The "zone method" described in Annex B.2 is used: The cross -section is divided into a number of parallel zones of equal thickness and their temperature -dependent compressive strength is determined. The reduced load -bearing capacity in the event of fire exposure is thus represented by a reduced structural component cross -section with reduced strengths.
If you define a parametric cross -section in the library via its dimensions, the geometric properties are coded in the cross -section description, for example "TO 200/100/10/10/10/10".
The RF-STABILITY add-on module determines the critical load factors, effective lengths and mode shapes of RFEM models. The stability analyzes can be carried out according to various eigenvalue methods, which have their advantages depending on the system and computer configuration.
General thin -walled cross -sections often have asymmetrical geometries. The principal axes of such cross -sections are then not parallel to the horizontal and vertical axes Y and Z. When determining the cross -section values, the angle α between the centroid axis y and the principal axis u is determined in addition to the principal axis -related moments of inertia.
The cross-section programs SHAPE-THIN and SHAPE-MASSIVE are suitable for determining the cross-section properties of common thin-walled or thick-walled sections. These cross -section properties are also available for further analyzes in RSTAB and RFEM.
In RFEM, surfaces are automatically connected if they have common boundary lines. If the definition line of a surface is lying in another surface, the line is automatically integrated into the surface, provided that it is a planar surface. In the case of quadrangle surfaces, however, the automatic object detection would be relatively complex. Therefore, the corresponding function is deactivated. The integrated objects must be specified manually.
In RFEM, RSTAB, and SHAPE-THIN, you can create user-defined print templates ("Printout Report Template") and printout headers ("Report Headers"). These templates can also be transferred to other computers and used there.
Model and load objects can not only be defined graphically or in tables, but can also be created using parameters (see manual ). With this parameterized input, you can also access cells of certain tables of the program. In this way, it is possible to link a load parameter with a model data parameter, for example. The reference is created by the $ sign.
The display size of the load vectors can be quickly adjusted in the load shortcut menu: Right -click the load icon and select "Increase Display Size" or "Reduce Display Size" from the menu.
