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.
For the design of the ultimate limit state of a fillet weld, EN 1993-1-8 provides the user with a simplified method under 22.214.171.124. According to this, the design is performed if the design value of the resultant force on the fillet weld surface is smaller than the design value of the weld's ultimate limit state. If you want to dimension the weld for a surface model, you will be faced with a variety of results due to the nature of FEM calculations. Therefore, the following section shows how to determine the force components from the model.
This technical article deals with the stability analysis of a roof purlin, which is connected without stiffening by means of a screw connection on the lower flange in the sense of a minimum manufacturing effort.
According to clause 3.2.2, EN 1993-1-3 allows the use of an average increased yield strength fya of a cross-section due to strain hardening.
In this example, we are creating a planar surface consisting of four nodes that have been imported and are apparently in a common plane, but in reality are not in one plane due to a previous modeling error of a few millimeters, for example. When trying to create a planar surface, the error message "Error defining surface! The nodes are not in one plane. "
This technical article analyzes the effects of the connection stiffness on the determination of internal forces as well as the design of connections using the example of a two-story, double-spanned steel frame.
If a rib is part of a nonlinear design or is rigidly connected to following walls, a surface should be used for the modeling instead of a member. So that the rib can still be designed as a member, a result member with the correct eccentricity is required, which transforms the surface internal forces into member internal forces.
The article Lateral-Torsional Buckling in Timber Construction | Theory explains the theoretical background for the analytical determination of the critical bending moment Mcrit or the critical bending stress σcrit for the lateral buckling of a bending beam. The following article uses examples to verify the analytical solution with the result from the eigenvalue analysis.
This article describes the design of timber panel walls due to generated horizontal loads.
Buildings are structures surrounded by wind. The flow around it creates specific loads on the surfaces, which are to be used for the design in structural analysis.
Nonlinear Calculation of a Floor Slab Made of Steel Fiber Reinforced Concrete in the Serviceability Limit State with RFEM
Describing the procedure for the serviceability limit state design of a floor slab made of steel fiber reinforced concrete. This article shows how to perform the corresponding design for the SLS by means of the iteratively determined FEA results.
