- Quantity: 20 bars (10 per bearing location)
- Bends: U-shape with 90° bends at top corners
- Spacing: 6” intervals around bearing plates
- Location: Y = ±30” (2 bearing plate locations)
- Critical: Extra reinforcement for beam load transfer
R8 - Corner Diagonal Reinforcement
Specifications:
- Length: 2’-0” (straight diagonal)
- Quantity: 8 bars (2 per corner)
- Bends: None (straight bars at 45° angle)
- Location: 4 re-entrant corners where walls meet
- Purpose: Prevents cracking at stress concentrations
R9 - Wing Wall Verticals
Specifications:
- Length: 3’-6” (6” lap + 36” wing height)
- Quantity: 16 bars (8 per wing = 4 positions × 2 faces)
- Bends: 90° hook at top
- Location: Wing walls (both at 29° angle)
- Spacing: 4 positions along 4.33’ wing extension
R10 - Wing Horizontal Ties
Specifications:
- Length: 2’-0” (straight, spans wing thickness)
- Quantity: 24 bars (12 per wing = 4 positions × 3 levels)
- Bends: None (straight bars)
- Levels: 6”, 18”, 30” above base (3 levels per wing)
- Purpose: Connects wing verticals, provides lateral stability
R11 - Expansion Joint Dowels ⚠️ SPECIAL
Specifications:
- Length: 2’-0” (half bonded, half smooth)
- Quantity: 12 bars (6 per wing)
- Bends: None (straight bars)
- ⚠️ CRITICAL TREATMENT:
- Left half (12”): Normal bond - embeds in main body
- Right half (12”): NO BOND - wrapped in plastic, embeds in wing
- Preparation: Coat with form oil, wrap with plastic tape
- Purpose: Allows wing to settle independently while providing shear resistance
R12 - Drainage Pipe Cages
Specifications:
- Length: 1’-6” (straight bars)
- Quantity: 16 bars (8 per pipe = 2 pipes)
- Bends: None (straight bars parallel to pipe)
- Pattern: Octagonal cage around 4” PVC pipe
- Location: Y = ±18” (two drain pipes)
- Purpose: Reinforces concrete around pipe openings, prevents cracking
