David,

2 areas that I wish were researched and cheap to do are the following:

Anchor bolts:
At what size does the head of an anchor rod size loose the ability to
develop the cone.  When one calculates the bearing pressure under the head
of a cast in place anchor rod, it is very large.  The testing would consist
of taking a series of anchor rods and machining the head smaller and smaller
and testing them until the cone fails to develop.  I have a ton of research
papers that touch on the subject, but none address it directly.

Steel wide flange beam reinforcement under load and unloaded:
This topic has again been addressed only indirectly, and I could provide you
with the references.  The question is what effect does an existing load on a
beam have when one welds reinforcing plates on the beam.  The testing would
be to take a series of wide flange beams, load the beams to an incremental
percentage of its capacity, weld reinforcing plates on the beam, and load
the reinforced beams to yield.  The control would be taking the same series
of beams, weld the reinforcing plates on the beam with no load, then load
the beams to yield.

If you want to get into specifics, contact me off line at spragueho(--nospam--at)bv.com.

Regards,
Harold O. Sprague
