What wood wall design method should I use?
RISA-3D is one of the few pieces of software on the market offering wood shear wall analysis and design accompanied by multiple design methods to best suit your detailing needs.
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…

Applying a Custom Rebar Layout in RISA-3D: To begin creating a custom rebar layout, simply click the Custom Rebar Layout button located in the Advanced tab of the ribbon toolbar.
In RISA-3D, the current method of design for masonry lintels is Simply Supported where the masonry lintels are idealized into a simply supported pin-pin beam configuration. Now, masonry lintels can instead be analyzed using finite element analysis. With this method, the lintel will be fully...
The 2015 NBC compliant codes have been implemented into RISA-3D v17.0, RISAFloor v13.0 and RISAFoundation V.11.0!
The 2016 edition of ASCE Minimum Design Loads and Associated Criteria for Buildings and Other Structures (ASCE 7-16) is now available in RISA-3D v17.0, RISAFloor v13.0, and RISAFoundation v11.0!
Eurocode lateral torsional buckling capacity is calculated per equations in Annex F in the ENV 1993-1-1:1992. This calculation uses variables C1, C2 and C3. Since there is no generic formula in the Eurocode to calculate the moment gradient factor, C1, RISA will use the widely accepted López, Yong...
With the initial implementation of wood wall design in RISA-3D, the wall aspect ratio was calculated as the full height of the wall divided by the width of the region.This was intended to accommodate balloon framed multi-story walls that were drawn as one continuous wall stack. With recent...
With the recent release of RISA-3D v17 the program now offers the user the option to use Chord Straps between floors of a wood shear wall building in lieu of using hold downs. Chord Straps are a great option for transferring tension load between floors of a multi-floor building and can be installed...
RISA-3D v17.0 now has the ability to model partial fixity member end releases. Partial fixity end releases can be utilized in RISA to model the behavior of a partially restrained or semi-rigid connection that cannot be idealized as fully fixed or pinned. Partially restrained connections are common...
