This tutorial guides you through a complete specification workflow — from creating a project to exporting your final documentation.

Scenario

We’ll specify a facade bracket connection with the following requirements:
  • Application: Steel bracket supporting a curtain wall mullion
  • Concrete: C30/37, cracked conditions
  • Loading: 15 kN tension, 8 kN shear (factored ULS values)
  • Edge distance: 100mm from slab edge

Step 1: Create the Project

  1. Open Clariti

    Log in at clariti.site and click New Project from your dashboard.
  2. Name Your Project

    Enter a descriptive name: “Facade Bracket - Level 03” Good project names help you find work later. Consider including:
    • Building or project reference
    • Location or level
    • Element type
  3. Set Project Parameters

    Configure the base concrete properties:
    ParameterValueNotes
    Concrete classC30/37Characteristic strength fck = 30 MPa
    ConditionCrackedAssume cracked unless proven otherwise
    ExposureXC3Moderate humidity — typical for facades
    If you’re unsure about cracked vs. uncracked, assume cracked. It’s the conservative approach and covers most practical situations.

Step 2: Add a Connection

  1. Create New Connection

    Click + Add Connection in the project panel. A new connection appears in your project tree.
  2. Rename It

    Double-click to rename: “Bracket B-03-01” A systematic naming convention helps when you have many connections:
    • B = Bracket
    • 03 = Level 3
    • 01 = First bracket on this level
  3. Set Connection Type

    Select Single channel from the connection type options. Connection types available:
    • Single channel — one anchor channel
    • Channel pair — two parallel channels
    • Channel group — custom arrangement

Step 3: Define Geometry

  1. Member Thickness

    Enter the slab thickness: 200 mm This affects:
    • Available embedment depth
    • Concrete cone breakout area
    • Splitting resistance
  2. Edge Distances

    Define the distances from channel to concrete edges:
    EdgeDistanceLocation
    c₁100 mmTo slab edge (governs)
    c₂500 mmTo adjacent edge
    The 3D view updates to show your geometry. The warning indicator highlights that c₁ = 100mm may cause capacity reductions.
  3. Channel Orientation

    Set the channel axis:
    • Horizontal — channel runs parallel to slab edge
    • Load direction: Perpendicular to channel axis

Step 4: Enter Design Loads

  1. Load Values

    Enter your factored ultimate limit state (ULS) loads:
    ComponentValueDirection
    NEd15 kNTension (away from concrete)
    VEd8 kNShear (perpendicular to channel)
    MEd0 kNmNo moment
  2. Load Case

    These loads are already factored. Select ULS - STR as the limit state.
    Clariti expects factored design loads. Don’t enter characteristic (unfactored) values — you’ll get unconservative results.

Step 5: Select a Channel

The results panel now shows available channels ranked by utilization:

Option 1: Manual Selection

Browse the product list filtered to your requirements:
  1. Filter by material: Stainless steel (for facade exposure)
  2. Filter by manufacturer: All (or select preferred supplier)
  3. Sort by: Utilization (lowest first)
Click a product to see its detailed verification results.

Option 2: AI Recommendation

Click Optimize to let Clariti suggest the best option: The AI considers:
  • Capacity vs. demand (target 70-85% utilization)
  • Material suitability for exposure class
  • Cost efficiency
  • Commonly specified products for this application
For our scenario, Clariti recommends CPRO 52/34 in stainless steel.

Step 6: Review Results

With CPRO 52/34 selected, the results panel shows:

Concrete Cone Failure - EN 1992-4 Section 7.2.1.4

N°Rd,c = N°Rk,c / γMc

where:
  N°Rk,c = k₁ · √fck · hef^1.5 · (Ac,N/A°c,N) · ψs,N · ψre,N · ψec,N

Input values:
  k₁ = 8.9 (cracked concrete)
  fck = 30 MPa
  hef = 47 mm (effective embedment)

Factors:
  Ac,N/A°c,N = 0.72 (edge distance reduction)
  ψs,N = 0.85 (spacing factor)
  ψre,N = 1.0 (no supplementary reinforcement)
  ψec,N = 1.0 (concentric loading)

Calculation:
  N°Rk,c = 8.9 × √30 × 47^1.5 × 0.72 × 0.85 × 1.0 × 1.0
  N°Rk,c = 30.45 kN

  γMc = 1.5

  N°Rd,c = 30.45 / 1.5 = 20.3 kN

Utilization:
  NEd / N°Rd,c = 15 / 20.3 = 74% ✓

Step 7: Export Documentation

  1. Generate Report

    Click ExportPDF Report Select what to include:

    • Full calculations
    • Product data sheet
  2. Specification Text

    Click ExportSpecification Text Copy the generated text for your specification document:
