Powerful Tools Don’t Help If They’re Left Unused Many engineers evaluate analysis software based on core modeling and design checks. But once a demo is over, some of the most impactful features are the ones that quietly save time on real projects — especially mid-size jobs where efficiency matters most. These aren’t advanced edge-case tools. They’re everyday features that often go underused. Diaphragm Forces: See Load Paths Instead of Guessing Diaphragm force output is one of the most valuable — and least leveraged — parts of a full building model. Instead of relying on manual distribution or conservative assumptions, engineers can directly see how loads are flowing to vertical elements. For mid-size structures, this clarity can mean: Fewer overdesigned collectors More confidence in lateral load paths Faster review and revisions when layouts change Batch Results: Review Smarter, Not Longer Batch results allow engineers to review multiple load cases, members, or design checks in a single pass. Instead of hunting through individual reports, patterns become obvious quickly. On mid-size jobs, this speeds up: QA/QC reviews Iterative design changes Comparing “before and after” scenarios It’s not about skipping checks — it’s about seeing the full picture sooner. Design Iteration Speed Is the…

RISAFoundation was originally created as mat slab design software, but with some tweaks in the latest version (v6.0) it is now useful for slab on grade design as well. To get a design for slab on grade simply draw a slab element which has the appropriate thickness:
Now you have the ability to add in your customized company logo to a report.
RISAFoundation has the ability to export detailed reinforcement drawings for footings, pile caps, pedestals, and slabs.
This video shows how slab modifications can used to add an opening or change the thickness of a portion of the slab in RISAFoundation.
RISAFoundation includes a footing element which is represented by a single node. A frequent question that arises is how to apply multiple point loads to a single footing, but at different locations. This can be done with or without corresponding pedestals, but for the example below multiple...
RISAFloor, RISA-3D, and RISAFoundation all allow the user to export a model as a DXF file for use in most major CAD programs.
While RISAFoundation has a Default soil properties (Subgrade Modulus and Allowable Bearing), it is possible to create regions of varying soil properties.
RISAFoundation has the capability to report soil bearing pressures, and check them against allowable pressures.
