Approved Anchors cracked conrete for suspended ceiling in PT slab

Approved Anchors cracked conrete for suspended ceiling in PT slab

(OP)
Can anyone suggest an anchor that has an ICC approval for cracked concrete with maximum 3/4" embedment to resist seismic load. This is regarding anchorage for seismic bracing in a PT slab for 4psf of suspended ceiling. Using an X-ray to miss the tendons to hang a ceiling ( 8' o.c ea way)- is an overkill and highly uneconomical. But to find an anchor approved in cracked concrete with only 3/4" embedment is impossible. Any suggestions?

anti-gravity paint?

Short of direclty asking the anchor manufacturer's I'm not sure what anchor can get you what you need at 3/4" embed.

Why do you need x-rays?  Can't you just use the shop drawings and measure out where the tendons are?

OK, just kidding, but seriously, you may not need x-rays.  They make a drill with a sensor that stops the drill upon reaching a PT-tendon so the tendons will not be damaged.  

You may also want to consider using GPR to find the tendons which is a lot less expensive than x-rays.  Of course a lot depends on how much rebar you have in there.

Next time it may be easier to place embeds prior to concrete placement.
