Creating Opening in Existing Unbonded PT Slab
Hi Ingenuity, Understood. So, the rams are to pre-load the wedge, not the strand. Pre-seating the wedge to reduce impact loading before severing tendon. Thank you so much for patiently describing your method. May I ask where are you currently practicing structural engineering? I'm a...- FanGong

Creating Opening in Existing Unbonded PT Slab
Hi Ingenuity, Thanks for the detailed explanation. The intent is by stressing the ram on each side to about 15-16 kips, we pretty much end up without any pre-tension in the zone between point A and B right? Then cutting the strand at L/2 would not result in any sort of energy release. My...- FanGong

Creating Opening in Existing Unbonded PT Slab
Thank you Ingenuity. Sorry I was light on describing the conventional method, which absolutely involves careful scanning to locate the tendons, reinforcing and anchorage zones. I currently don't have this issue. However, going into CA for some new construction projects, I'd like to have a few...- FanGong

Creating Opening in Existing Unbonded PT Slab
The conventional method is to chip concrete, cut tendon, and then install new anchors, grout new anchor pockets and re-tension. I'm wondering if there's an easier way. Anyone had success using this anchor troubleshooting device? http://www.gti-usa.net/GTI-Trouble-Shooting-Anchor.shtml Thanks,- FanGong
