wood sill plate to pt slab connection?
greetings all,
i have a question regarding the connection of wood sill plates to a post tensioned slab. i am working on an apartment building that is wood framed. the wood framing will be supported by a post tensioned slab over a parking garage. i will need to connect the shear, load bearing and other walls for an apartment building to the pt slab. what solutions/connections have been done in your experience? is one connection better than another, easier to install? should the anchor bolts be cast integral with the slab? drilled after??? ( i keep seeing a tendon getting hit with this method ) i am looking for some suggestions. thank you for the help!

for pt slabs - cast anchors are probably the best. embedded steel plates with headed anchors also a possibility.
i agree that drilling a pt slab near its edge, where the tendons may be hit is a real concern...but you may know exactly where these are going to be positioned and drilling to a limited depth may be ok...
thanks for the info. i was thinking that anchor bolts cast in the slab was the best. i am anticipating the contractor wanting to drill and use sleeve anchors or epoxy. the embedded steel plates you mentioned would they be continuous with threaded studs for the plate or some other connection?
i guess for an embedded plate with wood framing, you'd set these at some spacing (4' o.c.?) and then weld threaded studs to them similar to a headed concrete shear anchor on a composite beam...then bolt the plate to the concrete floor.
continuous embedded plates are quite expensive.
