StructAuto builds precision automation tools for structural engineers — eliminating repetitive manual workflows and letting you focus on what matters: great engineering.
Every tool we build is grounded in real structural engineering practice — not theoretical frameworks. We automate the parts that slow you down.
Every formula is traced directly to AISC 341-16, AISC 360-16, and ASCE 7. No black boxes — you know exactly which provision governs every output.
Full read/write API access to your SAP2000 model. Loads, combinations, property modifiers, design overwrites — all set automatically and fully reversible.
"Return to Original" undoes every modification in the correct sequence. Your model is always one click away from its pre-automation state.
Geometry-based brace identification works with any member naming convention. No manual tagging, no group assignments — it just works.
100%+30% and 100%+100% bidirectional modes generate up to 16 capacity-design combinations per seismic load combination, covering the full seismic envelope.
A built-in software manual, detailed flowcharts, and a complete parameter reference give you full visibility into every decision the software makes.
Capacity Design of CB Frames fully automates the seismic capacity design of Ordinary and Special Concentric Braced Frames by connecting directly to your SAP2000 model via API. It computes expected brace capacity forces per AISC 341-16, applies them as point loads, generates all required load combinations, and prepares the model for a final steel design run — all in a single step.
Select frame type, loading direction, earthquake load case names, Omega₀, and optional P-Delta / Rho settings.
Attach to a running SAP2000 instance or browse to a .sdb file. The software takes full control via the SAP2000 COM API. Requires SAP2000 V23 or later with the SAP2000 COM API dependencies installed.
The software runs analysis, identifies braces, computes capacity forces, applies loads, and generates all load combinations automatically.
Trigger the SAP2000 steel design check. All members are designed against the new capacity-design combinations. Restore the model when done.
Perpetual license with 12 months of updates and support included. No subscriptions, no hidden fees.
excl. VAT — local VAT may apply
One-time perpetual license for one engineer. Ideal for individual consultants and design firms.
Unlimited seats, custom integrations, and dedicated support for large firms.
StructAuto was founded by structural engineers who spent years performing the same repetitive code-compliance workflows by hand. We built the tools we wished existed — precise, transparent, and deeply integrated with the software engineers already use.
Every product we release is backed by rigorous engineering verification, clear documentation, and a commitment to code-exact calculations. We don't ship black boxes — we ship tools you can trust and defend.
Work With UsOur team has hands-on experience designing steel structures to AISC, ASCE, and IBC standards. We know the workflows, the pain points, and what "correct" means.
Every formula, factor, and decision traces to a specific code provision. Full documentation ships with every product — not as an afterthought, but as a core deliverable.
Deep expertise in the SAP2000 API enables automation that goes beyond simple scripting — full model read/write access, design preferences, combination management, and more.
Every license purchase funds continued R&D. New tools, new design code updates, and user-requested features are roadmapped and delivered on an ongoing basis.
Join structural engineers who have already automated their seismic capacity design workflow with Capacity Design of CB Frames.

All licenses that have been revoked or replaced. A license is marked Replaced when a new active license exists for the same email; otherwise Revoked.
All payment transactions, including those from deleted accounts. Records are legally required to be retained for 10 years (Art. 2220 Codice Civile; D.P.R. 633/72; D.P.R. 600/73) and are preserved automatically when a customer deletes their account.
Deleting a payment record before the 10-year retention period has elapsed may constitute a violation of Italian accounting law and GDPR Art. 17(3)(b). Only delete records if legally instructed to do so, or after the retention period has expired.
