AStrutTie vs IDEA StatiCa
If you design D-regions — deep beams, corbels, pier caps, anchorage zones — with the strut-and-tie model method, IDEA StatiCa is the established desktop choice. AStrutTie is the web-based, STM-focused alternative: nothing to install, a fraction of the price, and built around strut-and-tie models with ESO-based topology optimization (deterministic and reproducible).
Here is an honest side-by-side so you can decide what fits your work.
| Feature | AStrutTie (Web) | IDEA StatiCa (Detail) |
|---|---|---|
| Platform | Runs in the browser — no install, any OS | Desktop app (Windows install) |
| Scope | Strut-and-tie model / D-region, dedicated | Concrete detail (CSFM) inside a full steel + concrete suite |
| Method | Classic STM + ESO topology optimization | CSFM (compatible stress field) + STM |
| Dimensions | 2D and 3D | 2D and 3D |
| Design codes | KDS (strength design & limit state), ACI 318, AASHTO LRFD, Eurocode 2 | Eurocode, ACI and others |
| AI assist | Review assist built in (rolling out) · model suggestions in development | Not offered |
| Subscription (entry) | From $100 / month ($1,000 / year) | Detail via Complete / Enterprise, approx. €1,750–4,990 / year |
| Perpetual license | $2,000 (Standard) / $3,000 (Pro) | Approx. €3,490–9,990 + annual maintenance |
| Evaluate for free | Always-free browser tier (no time limit) | Time-limited trial |
| Best fit | STM-focused work, fast setup, tight budget, Asia / Korea codes | Large firms, multi-material suite, established BIM workflows |
Why engineers pick AStrutTie
Nothing to install
Open a browser and model — Windows, Mac or Linux, on any machine. No license server, no IT ticket.
Pay for STM, not a whole suite
From $100/month. If you need strut-and-tie models — not the full multi-material toolbox — you don't pay suite prices.
Strut-and-tie models first
A dedicated STM workflow with ESO-based truss topology, 2D and 3D, and all major codes including Korean KDS.
Try before you commit
An always-free browser tier — no time limit. Existing AStrutTie owners get 3 months free on the web edition.
When IDEA StatiCa is the better choice
- You want CSFM continuous stress-field detailing, or one tool across steel, concrete and connections.
- You need deep BIM integration (Tekla, Revit) and an established, widely-referenced brand for validation and procurement.
Try the web edition — free, no install
Design a strut-and-tie model in your browser in minutes. No card, no download.
