Structural analysis & design · Brazilian ABNT codes

Professional structural engineering. Open source. On your machine.

HyperFrame analyses and designs reinforced-concrete buildings to the Brazilian codes (NBR 6118, 6120, 6123, 8681): 3D space frame with rigid diaphragms, wind loads, global stability (γz), column/beam/slab/foundation design, executive beam detailing with bar schedules, DXF drawings and a full calculation report — plus a built-in AI copilot (Claude API or local models via Ollama).

v0.2.28 · NBR 6118:2023 HyperFrame: 2D formwork plan with axes and dimensions beside the 3D model of an 8-storey building

What it does

The whole workflow, one file.

01
Model in minutes — grid-based 2D plan editor (columns, polyline beams, slabs auto-detected, stairs, water tanks, slab openings) with a synced 3D view and DXF underlay.
02
Analyse honestly — in-house 3D frame solver (6 DOF, skyline LDLᵀ), rigid diaphragms, NBR 6123 wind, global imperfections, two stiffness passes (ULS/SLS), γz stability, soil–structure interaction from SPT logs.
03
Design to the code — beams (bending/shear/torsion/cracking), columns in biaxial bending, solid and ribbed slabs (Marcus or grillage — flat slabs with real punching checks §19.5, including perimeter reduction near openings), stairs, tanks, footings/piles/caissons, fire (NBR 15200).
04
Detail like an engineer — executive beam detailing: bar cuts from the real moment envelope (shift rule "al"), hooks, lap splices, stirrup layout, editable rebar (n/ø per position) and a bar schedule on the drawing.
05
Deliver — formwork plans, sections, load plans and rebar drawings with ABNT title block, exported to DXF; searchable multi-page PDF calculation report written from scratch (zero dependencies).
06
Verify everything — 300+ automated tests anchored to hand calculations; the validation suite is public and reproducible. Engineering you can audit.

Open source

Free forever. Auditable forever.

Every line — calculation engine, desktop app and this website — is public on GitHub. Each release ships binaries, source code and checksums.
