What Loads Transfer from RISAFloor to RISA-3D?

RIAFloor designs the gravity system and then integrates with RISA-3D to design the lateral system. Only the lateral members are taken from RISAFloor over to RISA-3D. The loading is automated in this integration so one of the most common questions is: what loads are transferred when switching from RISAFloor to RISA-3D? Below is the brief explanation to answer this question. Gravity Loads: The lateral members that become part of the RISA-3D model bring over their gravity loads. This also includes the beam reactions from the gravity only members that were not transferred in to RISAFloor. The load categories in RISAFloor are automatically converted into Basic Load Cases in RISA-3D. The exception to this are the Load Categories that deal specifically with construction loads (DL Const and LL Const), which are not converted. Wind Loads: The wind loads are automatically calculated as the RISAFloor model gets integrated into RISA-3D. The wind load parameters are located in the Wind tab of the Global Parameters in RISAFloor. However, these settings may also be changed when the wind load dialog pops up when transferring to RISA-3D: The option to generate roof wind loads are only present in RISA-3D models that are integrated with RISAFloor…

RISA-Tekla Link v10 Released

The release of the RISA-Tekla Link v10 introduces compatibility with Tekla Structures V2020. This update of the link includes the following features as well as other enhancements: Added the ability to align the top of beam elevation using detailing information and cardinal points. Added the ability to round-trip rigid link elements. These improvements are important because RISA-3D defines members by their analytical centerline for the structural analysis and design, while Tekla Structures defines members by their physical alignment for constructability and detailing purposes. Cardinal points are used to properly map member positions when a RISA-3D model is imported into Tekla. Additionally, cardinal points enable the engineer to specify the "true" elevations for member connections and alignment without affecting the structural analysis and design. Another new improvement included in the latest release of the RISA-Tekla Link is the support for rigid links. Rigid links can be used to tie members together, such as in the example of two stacked wide flange beams, modeled with rigid links so that the members act compositely (see image below). For a complete list of all the improvements and corrections included in version 10 of the RISA-Tekla Link, click the button below to review the release…

RISA-Revit Link: Adding Shapes

Integrating structural models from RISA to Revit seamlessly can sometimes present challenges, especially when it comes to importing shapes accurately. Unlike RISA, Revit operates on a different system, requiring users to preload family shapes for drawing or importing purposes. In this support article, we'll delve into the process of adding shapes to Revit from RISA, ensuring a smooth transition between the two platforms. Let's navigate through the steps together to optimize your workflow and enhance your structural modeling experience. Why Do I Need To Do This? REVIT does not automatically bring your RISA model's section shapes in. Revit requires the user to select individual shape families to be brought into the model file. Once you've gone through the list and added the shapes that you will be bringing over from RISA, you can then perform the import from RISA which will eliminate warning messages and will bring over the shapes as modeled in RISA. How To Add Revit Family Shapes: In the following import example, we will show step-by-step how to add Revit family shapes. In this case, to bring in a W shape member. So we'll need to load the steel W Shape Family. But you will follow the…
