Cast-in-channel calculation check
This sanitized sample presents the inputs, evaluated results and key assumption from a real Clariti design. It omits the private project and is not a manufacturer approval or a substitute for project-specific engineering review.
✓ Calculation checked
CPRO50-350 with M20 bolts
18 of 18 evaluated checks passed. The governing check was shear with lever arm at 99% utilisation.

| Load | Position | Tension | Shear |
|---|---|---|---|
| 1 | 75 mm | 3.25 kN | 5.0 kN |
| 2 | 225 mm | 3.25 kN | 5.0 kN |
Assumption requires confirmation
The passing result uses a restraint factor of αM = 2, assuming full rotational fixity at the bolt-to-bracket connection. If that connection cannot justify full fixity, this option should not be specified without redesign.

Non-applicable checks
Clariti marked these six checks as skipped; they are not included in the 18 evaluated checks.
- Concrete Blow Out Failure
- Steel failure of supplementary tensile reinforcement
- Anchorage failure of supplementary tensile reinforcement
- Steel Failure - Channel Bolt (Shear without lever arm)
- Supplementary Reinforcement - Steel Failure
- Supplementary Reinforcement - Anchorage Failure
Before and after
Clariti retained the 75 mm edge distance, 250 mm concrete member, original load positions and applied loads while testing practical changes to the channel, bolt, restraint and lever arm.
