I noticed that the maximum component is equal to zero for support forces of a result combination. In my clear system, I can easily see that this cannot be true. The minimum force is alright.
To solve this problem, you have to define the other RCs in the RC 4 as Permanent:
RC4 = RC1/permanent or RC2/permanent or RC3/permanent.
The result combinations 1 to 3 will be compared. The most unfavorable value returns the result.
