Structural section analysis, without the software.
SectAnalyst runs moment-curvature and P-M-M interaction analysis entirely in the cloud — sign in, build a section, get results. No installs, no licenses to manage.
Why a cloud-based tool
Access from anywhere
No installs, no license dongles, no version mismatches between the office and the field. If it has a browser, it runs SectAnalyst.
Your projects, synced
Save a section once and open it from your laptop, your desktop, or a jobsite tablet — it's all the same account.
Always up to date
New tools and fixes ship to everyone automatically. No manual updates, no re-licensing, no reinstalling.
Your work stays yours
The calculation engine runs entirely on our servers — nothing about how it works is ever sent to your browser.
What's included
Moment-Curvature Analysis →
Fiber-based M-φ analysis for any section: mix concrete, steel, and FRP materials, any shape, any rebar layout.
P-M-M Interaction (ACI 318) →
Full biaxial axial-load/moment interaction surface, nominal and φ-factored, plus demand-capacity ratio checks.
More tools — concrete, steel, masonry, timber, FRP, and foundation design — are on the way.
