Behavior of Aluminum Screen Enclosures in Strong Wind The TAC heard a presentation
from Dr. Forrest Masters of the University
of Florida Engineering School for Sustainable Infrastructure &
Environment regarding their study on screen
enclosures. Dr. Masters mentioned that
in the next few days 1:24 geometric scale experiments on wind tunnel load
testing will begin. Dr. Masters
mentioned for these 1:24 scale tests 3D printed models of structures are to
be used from at least two wind directions via a turntable mounted in the wind
tunnel. The question arose of
corrosion testing particularly on the fasteners and may need to be given
extra attention. This wasn’t under the
scope of this investigation but is addressed under Kurtis Gurley’s study that was presented at the 1:00
PM Roofing TAC. They are currently
waiting delivery on the equipment for corrosion testing. Also the question of
electrolysis will be addressed for the fasteners and it was stated that it
was part of that fastener study and it wasn’t clear on how much can be
accomplished to address issue of these material interactions. It was also stated that use of washers may
help with the electrolysis. It was
mentioned that how was the scale of the mesh done to account for the model
and also testing with water spray with live tests should be considered. It was stated that under small scales of
the mesh and models this may be difficult and isn’t equivalent to just
geometrically scaling the screen up. This was considered before and will be
addressed in future tests and will require a different kind of test with a
large wetted and unwetted screen. After discussion and questions the TAC voted unanimously in favor of
the interim report Investigation of Fastening of Wood Structural Panels for Opening
Protection The TAC heard a presentation
from Dr. Forrest Masters of the University
of Florida Engineering School for Sustainable Infrastructure &
Environment regarding their Structural
Panels for Opening Protection. There
was some questions posed by Dr. Masters for the panel on the sill type, and
use of drainage wall system with what type of air gap should be used. It was determined to be a 1 ˝ in. air gap. It was also stated that when these panels
are not in place what to do with the holes that are not being utilized that
part of the year and may leak. After discussion and questions the TAC voted unanimously in favor of
the interim report Dr. Masters also informed
everyone that the testing at the Gainesville facility is available to attend
and witness but to contact the lead investigator to confirm attendance |
