Hi guys

As I know,
in "Max" combination method with 6 "exp" load cases
allowable stress is from one of 5 load cases...

but I found some strange like below
LC51 : 78.7% (code stress/allowable stress, 198.1Mpa/251.8Mpa)
LC52 : 83.8% (209.7/251.8)
LC53 : 80.1% (201.7/251.8)
LC54 : 82.4% (207.3/251.8)
LC55 : 89.3% (211.2/236.5)
LC56 : 84.5% (199.8/236.5)
LC59 : 122.2% (211.2/172.8)

in this case, I think allowable stress of LC59 should be 236.5Mpa
not 172.8.....as I know, max case's allowable is from the load case which have max ratio(code/allowable)

Please let me know... why 172.8 can be specified as allowable of max load case...

below data is from CII
