While members (beams and columns) follow conventions tied to their local axes, interpreting results for wall panels, plate elements, and design strips requires a slightly different perspective. These elements deal with both in-plane and out-of-plane behavior, and the sign conventions can change...
RISA software products use different sign conventions depending on the product’s purpose and typical use case. While the conventions are logical within each program, they may appear inconsistent when moving between tools like RISA-3D, RISAFloor, RISAFoundation, and RISAConnection. This article...
Exploring a new structural design software purchase? If you’ve ever wondered how RISA’s software could fit into your structural design workflow, a RISA Software Tour is the fastest way to find out—no guesswork, no canned presentations. In this free, 1-hour session, you’ll meet 1-on-1 with a RISA...
We often get asked: “Should I model my foundation as a slab or a spread footing in RISAFoundation?” While both are valid options, they use very different analysis methods, and the results can vary accordingly. In this article, we’ll walk through a side-by-side comparison, using the same modeled...
Ensuring Your Slab is Fully Supported by Piles in RISAFoundation A common mistake when modeling pile-supported slabs in RISAFoundation is forgetting to zero out the soil properties. By default, RISAFoundation assigns a soil definition to all slabs, which introduces soil springs into the model. If...
Why RISAFoundation is Essential for Today’s Engineers? Incorporating RISAFoundation into your foundation design process is more than just a time-saver—it’s a powerful tool for enhancing the accuracy and quality of engineering deliverables. By automating the most tedious and error-prone aspects of...
Is your RISA-3D software solution running slower than you expected? There are a few things you can do during your model set up in order to make your model more efficient and reduce the solution time. RISA has compiled a list of our most common tips for solving a slow solution in RISA-3D.
RISAFoundation includes the added ability to move selected foundation elements. This includes beams, wall footings, piles, pedestals, slabs, etc. To access the move tools, click on the Modify tab in the toolbar.
In RISAFoundation, the Allowable Soil Bearing value is controlled by the Soil Region. This value is always taken as a Gross allowable soil pressure by default.
