Output

PROC004 JIB HEEL TUBE, Rev Date, 181295
Ab= 2*(Wb*Tf+Do*Tw)= 156.6
Iy= 2*(Tw*Do*Wb^2/4+Tf*Wb^3/12)= 5.118E4
Pl= Px/2+My/Wb= 43.67
fd= Px/Ab+FNsgn(Px,My)*My*(Do/2)/Iy= 0.484
fs= (Pl-fd*Tw*Do)*2/(PI*((Do+Di)/2)*(Do-Di)/2)= 0.6566
UF= fd/(Kd(Nk)*Fy(Nm))= 0.2064
UF= fs/(Ks(Nk)*Fy(Nm))= 0.4828
w= fd*Tw*Do/(Kt(Nk)*(Do-Di))= 1.625
