Reinforced-concrete shell post-processing
Strata
From finite-element shell results to reinforcement assessments, design maps and practical outputs.

THE MISSING DESIGN LAYER
Your FEM solves the model.
Strata helps reveal the structure.
Strata bridges the gap between raw shell results and a practical reinforcement layout. It combines visual assessment, connected-region clustering, section mechanics and patch-based reinforcement workflows—while leaving each design decision with the engineer.
WORKFLOW
From model connection to reinforcement-oriented outputs.
- 01
Connect
Connect to a SAP2000 model and retrieve shell geometry, section data and force results.
- 02
Define
Select shell groups, design actions, base reinforcement, sections and reinforcement levels.
- 03
Assess
Review Wood–Armer forces, MN efficiency, crack width, shear demand and governing clusters.
- 04
Rationalise
Integrate demand across bands and apply or refine orthogonal reinforcement patches.
- 05
Interrogate
Use maps, probes and section cuts to examine critical regions and local behaviour.
- 06
Output
Export CAD and IFC layouts, approximate schedules, Excel data and Word reports.
UNDERSTAND THE FULL SHELL
Combined behaviour, across the surface.
Compute Wood–Armer design forces and review bending, membrane action, reinforcement demand and MN interaction efficiency in an interactive 3D environment.
- Full-surface ULS efficiency maps
- Automatic connected-cluster identification
- Peak-efficiency navigation and filtering

ASSESS REAL REINFORCEMENT
Sections first. Raw forces are not a design.
Define multi-layer reinforcement in both shell directions, manage reinforcement levels and assess the section actually intended for the project.
- User-defined concrete and steel
- Top and bottom reinforcement layers
- Visible section assumptions

MOVE BEYOND ISOLATED CHECKS
Maps show where. Cuts explain why.
Interrogate local behaviour using result probes, section cuts and design bands. Integrate forces across a cut and inspect MN interaction, stress–strain state and detailed crack-width verification.
- Band-force integration
- Local MN interaction plots
- Detailed EN 1992-1-1 crack-width checks

TURN ANALYSIS INTO INTENT
Build reinforcement that can be discussed and drawn.
Use progressive reinforcement levels, connected design clusters and orthogonal patches to move from demand to a rationalised arrangement. Review it in 3D before export.
- Patch-based reinforcement upgrades
- 3D reinforcement review
- CAD, IFC, Excel and Word outputs

REINFORCEMENT-ORIENTED OUTPUTS
Carry the decision forward.
Export reinforcement layouts and design information for coordination, reporting and drafting support.


ENGINEERING JUDGEMENT
A design assistant—not a black-box optimiser.
Automatic patch generation is heuristic and must be reviewed. Rapid crack-width maps use machine-learning approximations; detailed EN 1992-1-1 verification is available through section cuts. Curved shells are not currently supported.
All reinforcement layouts, checks and exported outputs must be reviewed and approved by a qualified structural engineer.

FAQ
Direct answers.
What is Strata?
A Windows desktop application for post-processing reinforced-concrete shell designs from SAP2000 models. It translates shell results into reinforcement assessment, code checks, design maps and reinforcement-oriented outputs.
Who is it designed for?
Structural engineers designing reinforced-concrete slabs, walls and planar shell structures, including consultancies working with advanced or nonlinear finite-element models.
Does it replace finite-element software?
No. Strata connects to SAP2000 and post-processes its model and results. It is a decision-support tool, not an analysis solver or automatic design authority.
Which analysis software and licence are supported?
Direct connectivity is tested with SAP2000 V26 and V27. Strata requires a SAP2000 installation with working API access. Advanced and Ultimate licences are verified; other licence levels are not yet validated by fr.aime labs.
Which checks are included?
Wood–Armer design forces, MN interaction-efficiency assessment, ULS maps, shear-demand review and crack-width assessment to EN 1992-1-1. Detailed crack-width verification is available through section cuts.
How is the licence delivered and activated?
Gumroad delivers the licence key after purchase. An internet connection is required and the licence is validated at each Strata launch.
Are updates and support included?
Yes. Every plan includes continuous updates and support. Support priority is Unlimited, followed by Ten and One.
How is VAT handled?
Displayed prices exclude VAT. Gumroad calculates and handles applicable VAT during checkout.
Can firms purchase multiple licences?
Yes. Ten permits up to 10 activations under one licence key; Unlimited permits organisation-wide deployment under one licence key.
