Understanding Clariti’s results helps you make confident design decisions. This guide explains how to read and interpret the verification output.

​
Results Popup

After running optimization, a popup appears immediately showing:
  • Optimization Complete — Green checkmark indicates successful calculation
  • Max Tension Utilisation — Percentage and controlling failure mode
  • Max Shear Utilisation — Percentage and controlling failure mode
  • Max Combined Utilisation — Percentage for combined loading
  • Ask AI — Get AI assistance with understanding your design
  • View Results — Open the full results panel

​
Using Ask AI

Click Ask AI in the results popup to get instant help understanding your design. The AI assistant can:
  • Explain why certain failure modes are controlling
  • Suggest design modifications to improve utilisation
  • Help troubleshoot designs that don’t pass
  • Clarify calculation methodology and standards compliance
You can also access the AI assistant at any time through the Chat tab at the bottom of the design interface.

Results Overview

Clariti presents results at three levels:
  1. Summary — Pass/fail with key metrics
  2. Mode breakdown — Each failure mode’s utilization
  3. Detailed calculation — Full equations and values

Comparing Modes

Look at the spread between modes: Example A — Balanced Design: 
Steel tension:    45%
Concrete cone:    68%  ← Governing
Pullout:          52%
Splitting:        61%
All modes similar — well-balanced design. Example B — Single Mode Governing: 
Steel tension:    30%
Concrete cone:    92%  ← Governing
Pullout:          35%
Splitting:        55%
One mode much higher — design limited by concrete. Consider:
  • Larger embedment depth
  • Supplementary reinforcement
  • Higher concrete strength
When one mode dominates, address that specific limitation rather than simply selecting a larger channel.

Calculation Structure

1. Reference clause (EN 1992-4 section)
2. Design equation
3. Input values
   - Geometry
   - Material properties
   - Product data
4. Reduction factors (ψ values)
   - Each factor with its calculation
   - Source of each value
5. Characteristic resistance (Rk)
6. Partial factor (γM)
7. Design resistance (Rd)
8. Utilization (Ed/Rd)

​
Tracing Values

Every value shows its source:
  • [Input] — Your entered value
  • [ETA] — Product data from approval
  • [EN 1992-4] — Standard reference
  • [Calculated] — Derived from other values

​
Understanding Factor Reductions

​
Area Ratios (Ac,N/A°c,N)

Reduced from 1.0 when:
  • Edges are close (cone truncated)
  • Multiple anchors (overlapping cones)
  • Shallow members (depth limited)

​
ψ Factors

FactorReduces for
ψs,NClose edges
ψre,NNo supplementary reinforcement
ψec,NEccentric loading
ψh,VShallow members (shear)
ψα,VLoad angle to edge

​
Cumulative Effect

Multiple factors multiply together: 
NRd,c = N°Rk,c × (Ac,N/A°c,N) × ψs,N × ψre,N × ψec,N / γMc
If several factors are low, combined reduction is severe.

​
Common Result Patterns

​
Pattern 1: Edge-Limited Design

Symptoms:
  • Concrete cone or edge failure governs
  • Low ψs values
  • Warning about edge distances
Solutions:
  • Increase edge distance if possible
  • Add edge reinforcement
  • Select deeper embedment channel

​
Pattern 2: Steel-Limited Design

Symptoms:
  • Steel failure governs
  • High utilization on steel modes
  • Concrete modes have large margin
Solutions:
  • Select higher strength channel
  • Use larger profile
  • Consider multiple T-bolts

​
Pattern 3: Interaction-Limited Design

Symptoms:
  • Individual modes OK
  • Combined check fails
  • Moderate tension + moderate shear
Solutions:
  • Distribute loads (multiple T-bolts)
  • Select larger channel
  • Reduce combined loading

​
Pattern 4: Splitting-Limited Design

Symptoms:
  • Splitting governs
  • Thin member warning
  • Edge or spacing issues
Solutions:
  • Increase member thickness
  • Select shallower channel
  • Increase edge distances

​
Acting on Results

​
When Design Passes

  1. Review governing mode — understand the limitation
  2. Check margin — is there room for variation?
  3. Consider warnings — any coordination needed?
  4. Document — export calculation report

​
When Design Fails

  1. Identify failing mode(s)
  2. Understand the cause (geometry, loads, product)
  3. Consider options:
    • Different product
    • Geometry adjustment
    • Load redistribution
    • Multiple fixings
  4. Re-run verification
  5. Iterate until satisfactory
Don’t just select larger products blindly. Understanding why a design fails helps you find efficient solutions.
