Structural Analysis alternatives comparison
| Tool | Verdict | Composite | Price signal | Agent access | Key formats |
|---|---|---|---|---|---|
| Dlubal RFEM 6 A professional-grade FEA package with transparent perpetual pricing and a 90-day trial -- steep upfront but you own it, and the modular add-on system means paying only for the code checks you need. | Worth it | 4.2 | One-time | API | IFC, DXF, SAF, SDNF |
| SkyCiv Best entry point for cloud FEA -- transparent pricing, no installation, and 24/7 engineering support make it unusually accessible. | Solid | 3.8 | Subscription | API | IFC, DXF, RVT, JSON |
| STAAD.Pro The broadest international code coverage and a 40-year track record, but at $3,995+/year with no free trial and an enterprise-oriented feature set, it is priced and scoped for high-volume structural practices. | Solid | 3.8 | Subscription | API | IFC, ISM, CIMSteel/2, DXF |
| CSI ETABS Solid for multi-story building analysis and seismic design -- the CSI OAPI (VBA/VB.NET/C#/C++/Python/MATLAB, shared with SAP2000/SAFE/CSiBridge) is genuinely scriptable, with public perpetual pricing from Plus $7,293 to Ultimate $17,504; CSI does not officially support third-party OAPI tooling. | Solid | 3.6 | from $7,293 | API | EDB, IFC, E2K |
| IDEA StatiCa Solid -- industry-leading steel connection design with patented CBFEM technology, transparent pricing (annual EUR 1,750-4,990, 14-day free trial), and integration with 40+ FEA/CAD tools; however API access requires Enterprise tier and the desktop-only interface (no CLI/MCP, RF2) limits agent-driven workflows. | Solid | 3.6 | Free trial | API | IFC, DXF, CIS/2 |
| RISAFloor Solid -- RISAFloor is a practical companion to RISA-3D for multi-story gravity framing, with public pricing, a free trial, and a clear Revit round-trip path, but it stays in the desktop-engineering lane with limited agent automation. | Solid | 3.6 | Free trial | None | DXF, RVT |
| ClearCalcs The most approachable structural calc tool -- inspectable code-referenced outputs, concurrent-user licensing, and transparent per-month pricing make permit documentation fast and audit-ready. | Solid | 3.4 | Subscription | API | PDF, CSV |
| CSiBridge Solid -- purpose-built for bridge analysis with the same CSI OAPI automation layer (VBA/VB.NET/C#/C++/Python/MATLAB) shared with SAP2000 and ETABS, giving it genuine agent-driven scripting capability; the same csiamerica.com/sales page that publishes SAP2000/ETABS perpetual pricing also lists CSiBridge tiers from Plus $13,391 to Advanced with Rating $29,756 (plus annual maintenance), so the pricing-wall objection no longer applies, though CSI does not officially support third-party OAPI tools. | Solid | 3.4 | from $13,391 | API | BRG, IFC, E2K |
| PGSuper / BridgeLink (WSDOT) Solid -- a genuinely free, open-source, actively maintained bridge design and load-rating suite from WSDOT (current v9.0.2, June 2026 release) with AASHTO LRFD support and a programmable Washington Bridge Foundation Library (WBFL) SDK in C++; the only cost is learning the DOT-grade workflow, and there is no cloud API/CLI (RF2), but for a free tool with no vendor lock-in this is the best value proposition in bridge structural software. | Solid | 3.4 | Free tier | API | CSV, XLS |
| SAP2000 Industry-standard general-purpose FEA with 45+ years of solver development -- powerful for complex or non-building structures, but opaque pricing and no self-serve purchase path add friction. | Solid | 3.2 | Contact sales | API | IFC, DXF, SAP2000 .SDB |
| SCIA Engineer Solid -- SCIA Engineer publishes real subscription pricing ($827/user/month billed yearly), offers a 30-day trial, and covers concrete, steel, timber, and bridge-scale structural analysis in one desktop stack, but automation remains workflow-level rather than API-first. | Solid | 3.2 | from $9,924 | None | IFC, SAF, DXF |
| FRILO Solid -- FRILO is one of the more transparent structural suites in this segment, with edition pricing starting at EUR 244/month and a free trial, plus a broad catalog of everyday structural and foundation modules, but it is still a desktop engineer tool rather than an automatable platform. | Solid | 3.2 | Free trial | None | PDF, IFC |
| Tekla Tedds The best dedicated calc-sheet automation tool for routine structural design -- audit-ready output and multi-code coverage, but pricing is quote-only and Trimble lock-in is real. | Solid | 3.0 | Subscription | API | PDF, IFC, RVT, DWG |
| RAM Structural System Solid -- RAM Structural System is still one of Bentley's clearest building-structure specialists, with current 2026 code-support docs, a documented data-access API, and direct Revit/Tekla/OpenBuildings handoff, but the $4,856/year seat price and Windows desktop deployment keep it in specialist-practice territory. | Situational | 2.8 | from $4,856 | API | DXF, XML, SQLite, ISM |
| ProStructures Situational -- ProStructures is a serious detailing environment with IFC/DGN/DWG interoperability, parametric automation, and a documented API for custom tools, but at $9,536/year it is priced for firms doing fabrication-grade steel or rebar output every day, not occasional building-model cleanup. | Situational | 2.8 | from $9,536 | API | IFC, DGN, DWG |
| WoodWorks (AWC/CWC) Code-compliant wood design suite with free updates, concurrent licensing, and 10-day trial -- purpose-built for residential light-frame and mid-rise wood structures (up to 6 stories for Shearwalls), with Revit (MWF Pro Wood) and cadwork interfaces, but no public API/CLI/MCP (RF2) and a proprietary project format. | Situational | 2.8 | Free trial | API | WoodWorks project files, CAD (via cadwork), IFC (via Revit/MWF) |
| SOFiSTiK Situational -- a proven European bridge-engineering FEA/BIM platform (founded 1987, 15,268 LinkedIn followers, public company, 5,000+ customers including Queensferry Crossing) with genuine BIM integration (SBIM, Revit add-ons, Rhino/Grasshopper interface) and AASHTO support for US bridge markets; but commercial pricing is entirely quote-required (RF1) -- the 30-day free trial enables evaluation but does not disclose cost, so a sales call is still needed before budget estimation; the desktop-centric delivery with Rhino/Revit scripting options supports agent-driven workflows at the intermediate level. | Situational | 2.8 | Quote-only | API | IFC, DWG, DXF, SAF |
| AASHTOWare Bridge Design and Rating Situational -- the de facto U.S. DOT standard for bridge design and load rating with AASHTO LRFD/LRFR support, an OpenAPI for system integration, and a collaborative state-DOT development model that guarantees alignment with agency workflows; published procurement pricing is available (FY2026 AASHTO catalog: Agency Discount License $6,850/year, single workstation $11,350-13,000/year), enabling cost estimation before RFP, though the tool is built for DOT-scale procurement cycles and carries a steep DOT-specific learning curve with limited applicability outside the U.S. public-agency bridge engineering market. | Situational | 2.6 | from $6,850 | API | None listed |
| Tekla Structural Designer Solid -- Tekla Structural Designer fills a gap between general analysis tools and Revit, with strong seismic design workflows and AI assistance. Quote-only pricing and Windows-only desktop deployment are the main friction points; C2 is held back by lack of CLI/MCP automation. | Situational | 2.6 | Quote-only | API | IFC 2x3, IFC 4, IFC 4.3, DWG |
| O-Calc Pro Situational -- the de facto pole loading analysis tool for U.S. utility and telecom joint-use engineering with advanced nonlinear FEA, NESC compliance, and multi-material support (wood/steel/concrete); but quote-only pricing (RF1), no public API, and narrow utility-pole scope limit broader structural engineering applicability. | Situational | 2.0 | Quote-only | None | CSV |
