Hello...

I have read a discussion in this forum about Earthquake acceleration and I have a case about a non linier condition with seismic acceleration and wind loads and i have do exactly in two way:

A)First way
Case 2 = W+T1+P1 (OPE)
Case 3 = W+T2+P2 (OPE)
Case 4 = W+T3+P3 (OPE)
Case 5 = W+P1 (SUS)
Case 6 = W+P2 (SUS)
Case 7 = W+P3 (SUS)
Case 8 = W+T1+P1+U1
Case 9 = W+T1+P1+U2
Case 10 = W+T1+P1+U3
Case 17 = L2-L8 (OCC) ALGEBRA
Case 18 = L2-L9 (OCC)
Case 19 = L2-L10 (OCC)
Case 20 = L17+L18+L19 (OCC) SRSS
Case 21 = L2+L20 (OPE) ABSOLUTE
Case 22 = L5+L20 (OCC) ABSOLUTE

B)Second
Case 17 = L2-L8 (OCC) ALGEBRA
Case 18 = L2-L9 (OCC)
Case 19 = L2-L10 (OCC)
Case 20 = L5+L17 (OCC) SCALAR
Case 21 = L5+L18 (OCC) SCALAR
Case 22 = L5+L19 (OCC) SCALAR
and so on

Which way is CORRECT?,i think ABSOLUTE way give me an analysis in worst case rather than SCALAR. About Wind Case, i do not write it here cause it will be to long but i do the analysis just like the seismic, in first way(A) i try to find the MAX Wind in X and MAX WIND in Z and then add it with SUS case to get the OCCASIONAL case, in second way(B) just the same way in SCALAR manner.
Am i missing something?
