- Create a new RFEM or RSTAB model.
- In General Data, activate the "Enable CAD/BIM Model" option under the Options tab.
- Use the "Import New Model - IFC" function in the Project navigator to import the desired Reference View IFC model under the "CAD/BIM Model" tab.
- Model a pseudo-surface without the influence of the wind geometry within the IFC model body.
- Open the "RWIND Simulation - Simulate and Generate Wind Loads" interface under the "Calculation" menu.
- Specify the wind to be applied in the "Wind Load" tab.
- In the "Settings" tab, select the "Export Surrounding Model" and "CAD/BIM Models" options in the "Export to RWIND Simulation" section.
- In the "Load Cases" tab, select the wind direction to be analyzed and open the RWIND Simulation environment using the "Open in RWIND Simulation" function.
- Use the imported IFC model in RWIND Simulation.
Question
How can I import an IFC model into the RWIND Simulation environment?
Using the "Beam Panel" thickness type, you can model timber panel elements in 3D space. You just specify the surface geometry and the timber panel elements are generated using an internal member-surface construct, including the simulation of the connection flexibility.
Use the "Rib" component to define any number of longitudinal ribs on a member plate. By specifying a reference object, you can automatically specify welds on it.
You have the option to perform the fire resistance design of surfaces using the reduced cross-section method. The reduction is applied over the surface thickness. It is possible to perform the design checks for all timber materials allowed for the design.
For cross-laminated timber, depending on the type of adhesive, you can select whether it is possible for individual carbonized layer parts to fall off, and whether you can expect increased charring in certain layer areas.
Among others, the following cross-laminated timber manufacturers are available in the layer structure library:
- Binderholz (USA)
- KLH (USA, CAN)
- Kalesnikoff (USA, CAN)
- Nordic Structures (USA, CAN)
- Mercer Mass Timber
- SmartLam
- Sterling Structural
- Superstructures listed in Lignatec Edition 32 "Cross-Laminated Timber of Swiss Production"
By importing a structure from the layer structure library, all relevant parameters are adopted automatically. The library is continually updated.
