Dear Colleagues,
Say if I have to apply wind on all the four sides (+x / +z / -x / -z) of an irregular structure/geometry, is it okay to consider only 2 positive cases (+x / +z) as Basic Load Case and generate 4 load combinations with 2 positive and 2 negative values? why? (else) what is the better way?
(e.g.) if DL is 1, WL+X is 2 and WL+Z is 3 then
1.4 DL + 1.4 WL+X
1 1 .4 2 1.4
1.4 DL + 1.4 WL+Z
1 1 .4 3 1.4
1.4 DL + 1.4 WL-X
1 1 .4 2 -1.4
1.4 DL + 1.4 WL-Z
1 1 .4 3 -1.4
unable to find a thread which might have discussed the same topic.
Please advise.
