Steel bar joists - steep slope 1

[pallencn]

I am designing a roof with a 12:12 pitch. Want to use steel bar joists (span parallel to slope), but am concerned about how to detail the seat and bearing condition. I have a joist catalog that provides seat heights for slopes only up to 8:12. Does anyone have information on seat heights, or any sage advice on things to watch out for? Bearing is on CMU at low end, structural steel beam at high end. Thanks.
