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.
