The biggest concern is the splitting of poor
concrete or masonry if used in such cases. Crushing of timber plates etc
must be a concern for grouted anchors too, no?
Thor Tandy P.Eng
wanted to take a quick survey, but I'll give you the background story of why
first. We were going over some in-house check items on a job I had
designed and detailed, me, the senior engineer I work under and a senior
engineer who is new with our company. The new senior who was checking
the job wanted to know why I wasn't using wedge anchors instead of the epoxy
rods I had shown on a detail connecting an existing sill plate to an
existing foundation. At his old office, they used them all the
time. My answer was that we just don't *ever* use wedge anchors, it's
an office standard to always use epoxy rods. So as I sat back and
watched as two senior engineers almost came to blows (well, sort of) arguing
the merrits of wedge anchors versus epoxy anchors, costs, benefits, ease of
installation, whatever, I just got curious. Is there anyone on the
list using wedge anchors for seismic loads?
know is that I don't use them because they are no good for tension
applications, and the torque required to install them correctly will crush a
wood sill plate. Anyone have any good uses for these little beauties
that contractors love? How about horror stories?
