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.
The elastic deformations of a structural component due to a load are based on Hooke's law, which describes a linear stress-strain relation. They are reversible: After the relief, the component returns to its original shape. However, plastic deformations lead to irreversible deformations. The plastic strains are usually considerably larger than the elastic deformations. In the case of plastic stresses of ductile materials such as steel, yield effects occur where the increase in deformation is accompanied by hardening. They lead to permanent deformations - and in extreme cases, to the destruction of the structural component.
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 stiffeners by means of a bolt connection on the lower flange to have 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.
In this example, we are creating a planar surface consisting of four nodes that have been imported and are apparently in a common plane, but in reality are not in one plane due to a previous modeling error of a few millimeters, for example. When trying to create a planar surface, the error message "Error defining surface! The nodes are not in one plane. "
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.
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.
