Understanding Clariti’s results helps you make confident design decisions. This guide explains how to read and interpret the verification output.
Results Overview
Clariti presents results at three levels:
- Summary — Pass/fail with key metrics
- Mode breakdown — Each failure mode’s utilization
- Detailed calculation — Full equations and values
Summary Panel
Overall Status
The primary indicator:
| Status | Meaning | Action |
|---|
| ✓ Pass | All checks satisfied | Proceed to specification |
| ✗ Fail | One or more checks exceeded | Redesign required |
Utilization Indicator
The utilization bar shows:
- Percentage of capacity used
- Color coding (green/yellow/red)
- Governing mode highlighted
Key Metrics
| Metric | What It Shows |
|---|
| Overall utilization | Highest individual mode |
| Governing mode | Which failure type controls |
| Combined utilization | Interaction check result |
Mode Breakdown
Tension Modes
| Mode | What Fails | Key Factors |
|---|
| Steel failure | Anchor/channel steel | Steel grade, cross-section |
| Concrete cone | Concrete breakout | hef, fck, edges |
| Pullout | Anchor bearing | Product-specific, fck |
| Splitting | Concrete splitting | Thickness, edges, spacing |
Shear Modes
| Mode | What Fails | Key Factors |
|---|
| Steel failure | Shear of steel | Steel grade, diameter |
| Concrete edge | Breakout to edge | Edge distance, direction |
| Pryout | Back-face breakout | Embedment depth |
Combined Check
Interaction between tension and shear demands.
Reading Utilization Values
Interpreting Percentages
| Utilization | Interpretation |
|---|
| 0-50% | Significant reserve capacity |
| 50-70% | Good design margin |
| 70-85% | Efficient design |
| 85-95% | Limited margin, verify carefully |
| 95-100% | At limit, consider alternatives |
| > 100% | Fails — redesign required |
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.
Warnings and Alerts
Edge Distance Warnings
| Warning | Meaning | Action |
|---|
| c < ccr | Edge causes reduction | Accept or increase c |
| c < cmin | Below minimum | Must increase c |
Spacing Warnings
| Warning | Meaning | Action |
|---|
| s < scr | Spacing causes reduction | Accept or increase s |
| s < smin | Below minimum | Must increase s |
Member Thickness Warnings
| Warning | Meaning | Action |
|---|
| h < hmin | Splitting risk | Increase h or verify |

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
| Factor | Reduces for |
|---|
| ψs,N | Close edges |
| ψre,N | No supplementary reinforcement |
| ψec,N | Eccentric loading |
| ψh,V | Shallow members (shear) |
| ψα,V | Load 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
- Review governing mode — understand the limitation
- Check margin — is there room for variation?
- Consider warnings — any coordination needed?
- Document — export calculation report
When Design Fails
- Identify failing mode(s)
- Understand the cause (geometry, loads, product)
- Consider options:
- Different product
- Geometry adjustment
- Load redistribution
- Multiple fixings
- Re-run verification
- Iterate until satisfactory
Don’t just select larger products blindly. Understanding why a design
fails helps you find efficient solutions.
Comparing Load Cases
When multiple load cases are defined:
Results Table
| Load Case | Governing Mode | Utilization | Status |
|---|
| LC1 | Concrete cone | 75% | ✓ |
| LC2 | Combined | 92% | ✓ |
| LC3 | Pryout | 45% | ✓ |
Identifying Critical Case
- Different cases may govern different modes
- Overall governing case has highest utilization
- Design must satisfy ALL cases
Case-Specific Issues
If only one case fails:
- Can that load case be revised?
- Is a local strengthening more efficient?
- Should the design accommodate all cases equally?
