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.
Using the RF-TIMBER CSA module, timber column design is possible according to the CSA O86-19 standard. Accurately calculating timber member compressive resistance and adjustment factors is important for safety considerations and design. The following article will verify the factored compressive resistance in the RFEM add-on module RF-TIMBER CSA using step-by-step analytical equations per the CSA O86-19 standard including the column modification factors, factored compressive resistance, and final design ratio.
For the design of the ultimate limit state of a fillet weld, EN 1993-1-8 provides the user with a simplified method under 18.104.22.168. 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 stiffeners by means of a bolt connection on the lower flange to have a minimum manufacturing effort.
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.
This article describes the design of timber panel walls due to generated horizontal loads.
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.
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.
When performing structural calculations, the derivation of forces from the roof to the foundations is one of the central tasks of the calculation in addition to the dimensioning of the cross-sections.
