Structural Impact

  • Design Load Increase
    • 13,777 pounds per bay; 8% increase
  • Original Perimeter Columns
    • W12X45
    • Design Load Capacity = 350 kips
  • Resized Perimeter Columns
    • W12X50
    • Design Load Capacity = 393 kips; 12.3% increase
  • Increased Steel
    • 30 Perimeter columns, each 38 ft. in length
    • Increase of 5 plf = 2.85 tons => $4,047.
