RISA-3D v18 Sneak Peek Videos
The new release of RISA-3D is right around the corner! Check out our teaser videos to enjoy a sneak peek at some of the most exciting new features!
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…

Last week, RISA employees spend two days volunteering at the Second Harvest Food Bank of Orange County, CA. Both days were spent at the Food Distribution Center, where staff and volunteers worked together to sort, package and distribute enough food to feed 250,000 men, women and children each...
Tension or Compression (T/C) Only members are commonly used in steel buildings when modeling braced frames that resist lateral load.
When modeling building structures using steel or composite steel floors, engineers typically utilize rigid diaphragms to distribute lateral loads (wind and seismic) to lateral load resisting elements such as shear walls, moment frames and braced frames. Rigid diaphragms represent a plane of very...
When using semi-rigid diaphragms in a RISAFloor/RISA-3D model, it is possible to see negative moments at the ends of pinned beams as a result of the link between the semi-rigid diaphragm and the beam-column connection.
RISA employees and their families recently participated in the 5th Annual Run4Water 5k at Mile Square Park where they raised over $6,400 towards the construction of wells that provide access to clean water to communities in Uganda. Congratulations to everyone involved and for more information about...
RISA-3D has two ways of automatically generating seismic-related Basic Load Categories (BLCs) which can be later referenced in the Load Combinations (LCs):
Connection design according to the new AISC 360-16 (15th Ed.) Steel Manual has now been implemented in RISAConnection. To select this code for your design, simply choose either LRFD or ASD from the Solution tab within the Global Project Settings. The addition of the new 15th Edition code, includes...
The most recent release of AISC 360-16 (15th Edition) includes changes to connection design for rectangular HSS shapes with applied concentrated forces. These changes are now included in RISAConnection v10.
