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 188.8.131.52. 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.
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.
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.
In this technical article, a hinged column with a centrally acting axial force will be designed by means of the RF-/STEEL EC3 add-on module according to EN 1993-1-2. We will use the National Annex of Germany here.
Using the RF-TIMBER AWC module, timber column design is possible according to the 2018 NDS standard ASD method. Accurately calculating timber member compressive capacity and adjustment factors is important for safety considerations and design. The following article will verify the maximum critical buckling in RF-TIMBER AWC using step-by-step analytical equations per the NDS 2018 standard including the compressive adjustment factors, adjusted compressive design value, and final design ratio.
Limiting Crack Widths According to DIN EN 1992-1-1 with and Without Direct Calculation in RF-CONCRETE
Eurocode 2 provides two ways to perform a crack width design. On the one hand, the crack width design according to 7.3.3 can be performed without direct calculation by means of tables for the limitation of the member spacing and diameter. On the other hand, the crack width wk can be determined directly according to 7.3.4 and compared with a limit value.
