What You Can Do

You can systematically evaluate connection capacity against applied loads, identify governing failure modes, and verify AISC 360 compliance. The skill generates professional design documentation including load path diagrams, capacity calculations, and engineering justifications that are ready for peer review, permit submissions, and inspector scrutiny.

Features

Connection capacity evaluation

assesses bolted and welded connections against applied moment, shear, and tension loads

Failure mode identification

systematically evaluates bolt shear, bearing, tension, weld rupture, block shear, and gusset plate failure

AISC 360 code compliance

verifies design against current AISC standards and industry best practices

Load path generation

produces clear visual descriptions of force flow through connection components

Design narrative production

creates structured engineering justifications with calculations and assumptions

Connection comparison

evaluates multiple design concepts to support value engineering and optimization decisions

Modification assessment

validates changes to standard connection details with capacity verification

Example Output

Example 1: Moment Connection Analysis

Connection Type: Welded moment connection, W24×68 to W24×68 Applied Load: 450 kip-ft moment, 80 kips shear

Load Path: Moment splits into tension/compression couple in flanges → top flange tension (225 kips) to top weld → bottom flange compression (225 kips) to bottom weld → shear transferred through web welds

Failure Mode Check:

  • Flange weld capacity (E70 fillet, 5/8"): 312 kips > 225 kips ✓
  • Web weld capacity (E70 fillet, 1/2"): 180 kips > 80 kips ✓
  • Gusset plate bearing: 95 kips > 80 kips ✓

Governing Failure Mode: Weld rupture (lowest capacity margin)


Example 2: Bolted Shear Connection Assessment

Connection Type: Double-angle connection, 9/16" A325 bolts Applied Load: 120 kips shear

Capacity Summary:

  • Bolt shear (8 bolts, 2 planes): 224 kips ✓
  • Bolt bearing (3/8" gusset): 156 kips ✓
  • Block shear (angle leg): 142 kips ✓
  • Angle leg rupture: 165 kips ✓

Recommendation: Connection adequate; consider bolt arrangement for better eccentricity distribution in high-seismic zones
