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.
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.
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.
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.
The design of cold-rolled steel products is defined in EN 1993-1-3. Typical cross-section shapes are channel, C, Z, top-hat, or sigma sections. These are cold-rolled steel products made of thin-walled sheet metal that has been cold-formed by roll-forming or bending methods. When designing the ultimate limit states, it is also necessary to ensure that local transverse forces do not lead to compression, crippling of the web or local buckling in the web of the sections. These effects can be caused by local transverse forces by the flange into the web as well as by support forces at the supported points. Section 6.1.7 of EN 1993-1-3 specifies in detail how to determine the resistance of the web Rw,Rd under local transverse forces.
Utilize the RF-/STEEL Cold-Formed Sections module extension to perform ultimate limit state designs of cold-formed sections according to EN 1993-1-3 and EN 1993-1-5. In addition to the cold-formed cross-sections from the cross-section database, you can also design general cross-sections from SHAPE-THIN.
Nonlinear Calculation of a Floor Slab Made of Steel Fiber Reinforced Concrete in the Ultimate Limit State with RFEM
Steel fiber reinforced concrete is nowadays mainly used for industrial floors or hall floors, for foundation plates with low loads, basement walls and basement floors. Since the publication of the first guideline by the German Committee for Reinforced Concrete (DAfStb) about steel fiber reinforced concrete in 2010, the structural engineer can use standards for the design of the composite material steel fiber reinforced concrete, which makes the use of fiber reinforced concrete increasingly popular in construction. This article describes the nonlinear calculation of a foundation plate made of steel fiber reinforced concrete in the ultimate limit state with the FEA software RFEM.
Different glasses and layer structures are available for glass structures which are used for different purposes. The following types are usually used: float glass, partly tempered glass, and toughened safety glass.

This article explains the individual material parameters of the steel fiber reinforced concrete and how to deal with these material parameters in the FEM program RFEM.
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 184.108.40.206) by means of SHAPE-THIN will be performed.
