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.
Designing Reinforced Concrete Compression Elements Subjected to Biaxial Bending with the Nominal Curvature Method
Daily tasks in reinforced concrete design also include designing compression elements subjected to biaxial bending. The following article describes the different methods according to Chapter 5.8.9, EN 1992-1-1, which can be used to design compression elements with biaxial load eccentricities by means of the nominal curvature method according to 5.8.8.
When calculating the internal forces for the buckling analysis with the method based on nominal curvature in RF-CONCRETE Columns, the required eccentricities have to be determined.
With RF-/CONCRETE Columns, it is possible to determine effective lengths for columns automatically. This article describes which entries are necessary and how the calculation of the effective lengths is carried out.
It is possible to export the national parameters of EN 1992‑1‑1 for each country from RF‑/CONCRETE, RF‑/CONCRETE Columns and RF‑/FOUNDATION Pro. For this, there are the interfaces with MS Excel, OpenOffice, and CSV. By exporting the national parameters, you can edit them in MS Excel, for example, and display possible differences between the individual National Annexes in a clear way (see Figure).
The input for the minimum longitudinal reinforcement has been greatly improved in the RF‑/CONCRETE Columns module. In earlier versions, the minimum reinforcement could be defined either according to the design code or by specifying a minimum ratio of longitudinal reinforcement. Furthermore, it was not possible to define a specific amount of reinforcement, and instead the reinforcement had to be converted into a reinforcement ratio.
