i do encounter such cases most of my designs calculations,
my solution... may not be academic.
i design the members (coulmns and beams) with the stress envelop, if the strong column weak beam requirement fails, i modify the columns to meet such requirement to insure; as chigozie points out to; quote "To avoid catastrophic failure or collapse (brittle collapse)", increasing the column "I" generally satisfies the requirement, then again you tend to over design the columns, with that in mind, i would like to err on the side of safety.
my two cents on the matter.
