Hi, what is maximum bearing temperature of cp 620 and cp 636 fire-stop mortar .

The Pp result does not match the equation. It seems that the result is already multiplied by phi (0.65). And this Pp is being multiplied again by 0.65 to calculate X.

Kwik Bolt TZ2 disappear when I change load type from "Static or quasi-static design" to "seismic design"

The anchors for a base plate were not installed properly and they will be cut flush with the concrete, my question is "How close can a post installed anchor be installed to a abandoned cast-in place anchor.  is there any reduction in capacities".
