Hello stressers,

I have an inquiry about Slt sustain stress. My question is : Should I take maximum Sl from All operating cases including operating case plus occasional or only normal operating case

for example

L1= W+P1+T1 Operating
L2= W+P1 Alt sustain
L3= W+P1 Sustain
L4= W+P1+T1+Win1 oper+occ
L5= W+P1 Alt sus
L6= L2,l3,l5 max
L7= L1-L3
L8= L4-L1
L9= L7+L5

is that write to take max Sl and add it to pure wind to get occasional stress? and also in calculating Sa for displacement range Sl is taken from max L2 and L3 only or from max L2, L3 and L5
