    Uplift Question RE carport

    Dear swm25: Yes, so it would seem. But whether on not wind gusts would or should be resisted by extra-high component strength at the truss / beam connections, the governing concept of resisting uplift forces resides in main wind-frame and foundation analysis, and is independent of "components...
