Why do the results of a combination of load cases differ from the RC created from load combinations?


When creating a load combination, the calculation method "2nd Order" is preset in the calculation type by default. For linear systems, however, which are statically indeterminate, the results for load cases, which are calculated according to the 1st Order analysis, can be different.
