Connection at the base of Tilt-up panels

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I'm working on a single story concrete tilt-up building.  It is desired to
use hooked dowels at the base of the wall to transfer the shear to the
closure/footing/slab by means of shear friction.  The typical concrete walls
are 6" thick.

My understanding is, if you want to use shear friction, the dowels must be
embedded at least their minimum embedment length or a have "mechanical
anchorage".  Is adding an additional horizontal bar at the outside of the
wall and hooking the dowel around it sufficient to provide "mechanical
anchorage"?  Is it permissible to reduce the allowable shear friction based
upon the embedment of the dowel?  How do you handle this situation?
