AI Lintel Design System
Automated lintel/ledger design with v7.0 AI capacity calculations, reinforcement optimization, and code compliance verification.
v7.0 Enhancements¶
? AI lintel sizing (optimal depth, reinforcement)
? Real-time capacity (load vs capacity instantly)
? Auto rebar layout (bars sized and positioned)
? Bearing validation (end support adequacy)
? Code compliance (ACI 318 automatic checks)
AI Lintel Design¶
Opening: 6' wide door
Load above: 4' × 100 PSF = 400 PLF
AI analyzes:
"Lintel span: 6'-0""
"Applied moment: 0.45 kip-ft"
"Minimum depth: Span/12 = 6" (rule of thumb)"
"Recommended: 12" depth (adequate + tolerance)"
Reinforcement:
"Required As: 0.15 sq in"
"Minimum: 2-#4 bars (As = 0.40 sq in) ?"
"Provide: 3-#4 bars (SF = 2.7) ?"
Bearing:
"Required: 8" each end (code minimum)"
"Provide: 12" (tolerance + safety) ?"

Real-Time Validation¶
Instant Feedback:
As user changes parameters:
Span: 4' ? Capacity: ? Adequate
Span: 6' ? Capacity: ? Adequate
Span: 8' ? Capacity: ?? Marginal
Span: 10' ? Capacity: ? FAILS - Add bars!

Auto Rebar Layout¶
Optimized Reinforcement:
AI determines bar configuration:
Bottom bars (tension):
- Count: 3 bars
- Size: #4 (adequate for span)
- Position: 2" from bottom (cover)
- Extension: 24" beyond opening
Top bars (compression/skin):
- Count: 2 bars
- Size: #3 (minimum)
- Position: 2" from top
Stirrups (shear):
- Size: #3
- Spacing: 8" o.c. at ends
- Spacing: 12" o.c. at center
Total: Optimized for cost + capacity
Enhancement Status: ? v7.0 ENHANCED [14/38]
