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 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.
Limitation of crack width 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 analysis. On the one hand, the crack width analysis according to 7.3.3 can be performed without direct calculation by means of tables for the limitation of the bar 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 creating 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 themselves.
In RF-PUNCH Pro, you can perform the punching shear design on wall corners and wall ends. The basis for the design is the punching load, which is automatically determined from the RFEM internal forces in the connected surface. Since the surface internal forces from the RFEM calculation may be subject to the influence of singularity locations, this can also have a negative influence on the determined punching load at the wall corner or end. This article describes possible optimization options that you can use to minimize this unfavorable influence.
The beam is resting on the column and the beam ends at the outer edge of the column. These requirements can be easily fulfilled in an architectural model with solids. In member analysis, simplified line models are used in which center lines meet in a common node. In this article, the influence of member eccentricities on the determination of internal forces is shown on three simple models.
In the existing standard, there were no regulations for the distribution of snow loads for elevated solar thermal and photovoltaic systems on roofs. It was only advised to distribute the loads. Only with the National Annex DIN EN 1991-1-3/NA: 2019-04, concrete rules have been taken for this.
When you perform the subsequent modeling of a beam under an existing floor, the first question arises which forces should be transferred between the downstand beam and the floor and whether a composite effect is the goal. In this case, the floor should rest on the downstand beam without any composite.
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.
In RFEM and RSTAB, you can use many interfaces to simplify the modeling of your structure. From background layers to the import of IFC objects that can be converted into members or surfaces, up to the import of the entire structural system from Revit or Tekla. Regardless of the performance of the selected interface, the further utilization also depends on the accuracy of the imported data.
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.
