    Tilt-Up Connections

    I am working on a Tilt-Up warehouse in central California and I would like some feedback about a detail for supporting purlins at a panel joint. I have seen photos of similar details but I am not sure they are appropriate for my project. The proposed detail involves placing an embed with 4...
