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.
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.
Slender bending beams with a large h/w ratio and loaded parallel to the minor axis tend to have stability issues. This is due to the deflection of the compression chord.
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.
In the following, a hinged column with a centrally acting axial force and a line load acting on the strong axis will be designed by means of the RF-/STEEL EC3 add-on module according to EN 1993-1-1.
The following study compares the wind pressure on a tall building obtained by RWIND Simulation with the results published by Dagnew et al. at the 11th Americas Conference on Wind Engineering in June 2009. In this paper, the Commonwealth Advisory Aeronautical Council (CAARC) building is used as a model and results of several different numerical methods are compared with experimental data obtained from wind-tunnels.
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.
Assumptions for the Effective Tensile Strength Connected with Determining the Minimum Reinforcement According to DIN EN 1992-1-1 7.3.2
When determining the minimum reinforcement for the serviceability limit state according to 7.3.2, the applied effective tensile strength fct,eff has a significant influence on the determined amount of reinforcement. The following article gives an overview about determining the effective tensile strength fct,eff and the input options in RF-CONCRETE.
This article shows the effect of the different stiffnesses of the timber panel walls on the floor plan.
If you read out the results of a surface via the COM interface, you get a one-dimensional field with all results at the FE nodes or grid points. To get the results on the edge of a surface or along a line within the surfaces, you have to filter out the results in the area of the line. The following article describes a function for this step.
In RF-PUNCH Pro, enlarged column heads can be arranged at point-supported punching shear points, thus increasing the shear force resistance of a reinforced concrete floor. In the following article, we will show the punching shear design with the optional application of an enlarged column head.
