Question

The following loads were computed for designing a column in a 
frame:
• Dead Load = 200 K
• Roof Live Load = 50 K
• Live Load from floors = 250 K
• Compression Wind = 128 K, Tensile Wind = 104 K
• Compression Earthquake = 60 K, Tensile Earthquake = 70 K
Determine the critical design column load PU using LRFD combinations.

 

Expert Solution
Step 1: Introduction and given data

Given values,

  • Dead load, D = 200 k
  • Live load from floors, L = 250 k
  • Load from roof, Lr=50 k
  • Compression wind = 128 k
  • Tension wind = 104 k
  • compression earthquake=60k
  • tensile earthquake=70k
  • Snow load = 0
  • Rain load = 0

D = dead loads
E = earthquake loads
L = live loads (floor)
Lr = live loads (roof) 
R = rain load
S = snow load
W = wind load
