CL(95) = 20*LL(95)
= 20*[5*DL(95)]
= 100*DL(95)
= 100*(95/15)DL(15)
= 100*6.33*DL(15)
= 633*DL(15)
= 633 Force Units of upward support
whereas -
CL = Collapse Load for 100% & Total Collapse
LL = Live Load = Occupied & Furnished Weight
DL = Dead Load = Unoccupied, Unfurnished
110 = 110 Floor Steel WTC
95 = 95 Floor Steel Block (Lower Block)
15 = 15 Floor Steel Block (Top Block)
20 = Collapse Load Factor of John Skilling
5 = Live Load Factor of Ronald Hamburger
of NIST

Is this WTC7 related?
