When to reach for each

SAP2000 is the right tool for general-purpose FEM structural analysis: bridges (segmental box girders, truss, arch), industrial structures (pipe racks, platforms), offshore structures, stadiums, and specialty geometries. FrameAI is the right tool for connection-level detail design and fabrication output: EN 1993-1-8 bolt/weld/plate checks with full component method, autonomous PDF drawing intake, and DSTV NC1 CNC export. Many engineering teams use SAP2000 for bridge and industrial structural analysis and FrameAI for connection sign-off and shop-drawing production.

Migration — Moving from SAP2000

Your .sdb file import path

The recommended workflow to bring your SAP2000 model into FrameAI:

  1. 1
    In SAP2000: File → Export → IFC 4 (.ifc)
    Export your structural model as IFC 4. SAP2000 OAPI (.NET 8, updated v27) can automate this step in a CI/CD pipeline.
  2. 2
    Upload .ifc to FrameAI (or drop the original PDF)
    FrameAI accepts IFC 4 imports and structural PDF drawing sets. GPT-4o extracts members, connections, and loads automatically.
  3. 3
    FrameAI runs EN/AISC connection design + DSTV NC1 export + parametric shop drawings
    Full EN 1993-1-8 connection checks, DSTV NC1 7th edition fabrication export, and DXF/PDF parametric shop drawings — ready for your fabrication team.

FrameAI also accepts SAF v2.x for round-trip workflows. For automation, the SAP2000 OAPI (.NET 8, updated v27) can script the IFC export step as part of a CI/CD pipeline.

Worked example — LTB check on unrestrained steel beam

Case study: EN 1993-1-1 §6.3.2 lateral-torsional buckling

A 9 m unrestrained IPE 450 in S355 with a midspan point load of 120 kN. FrameAI extracts the member from the uploaded structural PDF, computes the elastic critical moment Mcr via the 3-factor formula, classifies the section, and returns χLT = 0.61 with a utilisation of 0.87 — all in under 30 seconds from PDF upload. No SAP2000 model rebuild required.

Frequently asked questions

Can FrameAI replace SAP2000 for structural analysis?
No, and we're explicit about this. SAP2000 is a general-purpose FEM solver covering bridges, industrial structures (pipe racks, offshore platforms), stadiums, and specialty geometries — not just buildings. FrameAI is purpose-built for the downstream connection-design and fabrication-output layer: EN 1993-1-8 bolt/weld/plate checks with full component method, autonomous PDF drawing intake via GPT-4o, and DSTV NC1 fabrication export. Many engineering teams use SAP2000 for bridge and industrial structural analysis and FrameAI for connection iteration and shop-drawing production.
Can I import my SAP2000 .sdb file into FrameAI?
FrameAI does not directly read SAP2000 .sdb files, but the import path is straightforward: in SAP2000, use File → Export → IFC to create an IFC 4 file, then upload that to FrameAI for EN 1993-1-8 connection design, DSTV NC1 export, and parametric shop drawings. FrameAI also accepts SAF v2.x and structural PDF drawing sets. Alternatively, upload the original PDF drawings and FrameAI's GPT-4o intake pipeline extracts members, connections, and loads automatically — no manual model entry required. SAP2000 OAPI (.NET 8, updated v27) can automate the IFC export step in a CI/CD pipeline.
Does SAP2000 export DSTV NC1 files for CNC steel fabrication?
SAP2000 does not natively export DSTV NC1 files for steel CNC fabrication. Fabrication-ready NC1 files typically require a Tekla Structures model or a dedicated nesting/CAM tool. FrameAI exports DSTV NC1 7th edition directly — correct neutral-axis BO coordinates, hole blocks, part marks, and all required sections — as a batch ZIP per project. If your downstream workflow goes to a CNC drill/saw line, FrameAI has a direct path that SAP2000 does not offer at all.
Where do SAP2000 member design checks end and connection design begin?
SAP2000 performs member-level design checks (cross-section class, utilization ratios under combined N+M) — it does not perform EN 1993-1-8 connection design (bolt groups, weld groups, T-stub behaviour, plate thickness checks). These require a dedicated connection tool. FrameAI's EN 1993-1-8 design engine performs full component method checks including end-plate, base plate, beam splice, and fin plate connections — with auto bolt-grade escalation (8.8→10.9→12.9) and weld auto-sizing. If your project requires EN 1993-1-8 connection sign-off, SAP2000 alone is insufficient — FrameAI closes that gap natively.
How does SAP2000 pricing compare to FrameAI?
SAP2000 Ultimate perpetual license is ~$17,855 USD + ~$3,128/yr annual SUM — confirmed from sehatdiri.com citing CSI official pricing, June 2025. Cloud sign-in only mandatory since July 2025. FrameAI is transparent: Free tier has 32 calculators with no login. Per-Discipline starts at $18/mo ($162/yr). Professional is $45/mo. Studio is $78/mo. No install, no maintenance contracts, no seat minimums. For a 3-engineer team, FrameAI Professional costs $1,620/yr vs SAP2000 at ~$27,239/yr per seat (perpetual + annual SUM) — a savings of ~$25,619 annually per seat.
Does FrameAI support the codes my project requires?
FrameAI covers EN 1993-1-1/1993-1-8/1992-1-1/1997-1/1998-1/1994-1-1/1995-1-1 with 9 National Annexes (NL, DE, BE, FR, IT, PT, RO, SI, HR), plus AISC 360-22, IS 800, IS 2911, GB 50017, GB 50007, AS/NZS 4600, and AIJ. SAP2000 covers EN with broad international codes, AISC 360-22 (v25.2+), IS 800 (v25.1+), GB 50017 (v25.3+), and AIJ. Neither currently supports the UK National Annex (BS EN 1993). For multi-code international projects, FrameAI has deeper coverage across Asian codes (IS, GB, AIJ) and is browser-native.
What National Annexes does FrameAI support vs SAP2000?
FrameAI supports 9 European National Annexes: NL (NEN-EN), DE (DIN-EN), BE, FR, IT, PT, RO, SI, HR. SAP2000 covers EN broadly but does not publish granular NA coverage in its feature matrix. Neither tool currently supports the UK National Annex (BS EN 1993). For Nordic projects, SAP2000 Ultimate supports NORRSOK; FrameAI does not yet. FrameAI's National Annex support extends to EN 1992-1-1, EN 1997-1, and EN 1998-1 with localized UI in EN/NL/DE.
How long does a typical FrameAI pipeline run take?
Active engineer time is 30–60 minutes end-to-end: PDF upload and GPT-4o extraction (~2 min), code standard configuration (~1 min), submit (~1 min). The autonomous overnight run processes EN 1993/1992/1997/1998 checks, connection design, and fabrication file generation while you sleep. Results are ready at 07:00: DXF shop drawings, DSTV NC1 batch ZIP, IFC 4 export, and connection reports with full utilisation ratios and escalation logs. Revision runs (e.g., after a drawing update) complete in the same overnight cycle.
