    Uplift anchors on residential slab on grade?

    Just as a clarification. The under-reams are located under the grade beams, both the perimeter grade beam and the interior grade beams as well.

    Reduced Anchor Bolt/Development Length

    I have a situation where anchor bolts need to be developed by using the pedestal reinforcing steel. The height of the pedestal is restricted due to existing conditions and limits on overall foundation depth. Lets say to fully develop a reinforcing bar in tension requires 30 inches. My...
