Who is the manufacture of the beam and do they have product
approval?

serious issue if it is based on the tables that I have seen. There is a
little voodoo math at play. The AESC conducted some physical tests and it is
my understanding the Track Beam did not perform as promoted.

I don't know who is supplying it but they boast a product approval. I
saw an ad for it as built by screen professionals inc.

beams.
David W Miller
The web portal address for the information is:
http://www.tracbeams.com/index1.html. You can download the available
information. There is sufficient dimensional information about the product
for someone with the time and patience to replicate the precise section in
Autocad and get appropriate cross-sectional mechanical properties. We've
asked for this information on several occasions and so far as I know, it is
not available.
The product approval span data appears to be bending/deflection without any
simultaneous axial stress (i.e. compression) applied.

David Miller, AAF Technical Committee
draw the sections in Autocad, get the properties, apply the values
using the 2005 ADM and get the allowable stresses (at least bending),
then publish the values on this discussion group. Share the autocad
sectional rendering so that any person familiar with the process can
use the information to get span data comparative to the legacy shapes.

David Miller, AAF Technical Committee
From: Do Kim, P.E.
<posted by David Miller by request from Do Kim, who does not have
posting priviledges>
To the Group:
I have not seen most of the past emails since it appears that my email
has been taken off of this group. David Miller, if that has occurred,
please put me back on the group list. I've also tried to log back in
as a new group member. I don't seem to be having any luck.
It's interesting to see all of the past comments. David Miller was
given the die prints for the Trac Beams over 8 months ago and as he
puts it, section properties could have been calculated very easily.
The 2005 AAF Guide specifically allows proprietary products to be used
in additional to the legacy shapes.
I've talked with many engineers about the revolutionary Trac Beam and
the FL product approval. The approval is based on tested results as
outlined in the 2005 ADM. So for the engineers that have never used
manufacturers' tested results, i.e. Tapcon fasteners, Simpson Strong-
Tie components, Castcrete lintel beams, etc...
They are all based on tested results and you can not calc-out the
results. So the product approval has allowable load and deflection
information based on tested results...just like the previous products.
I'm sorry if I'm repeating things for engineers that are already
familiar with standard engineering practices related to this topic.
Any company or engineer wishing to use the Trac Beam can be available
from FEI, T&C, and American Metal Supply. Designers..all you have to
do is use the allowable load on the product approval (which is
publicly available on the State of Florida website or www.tracbeams.com)
and convert it to an allowable uniform load and combine other stresses
as part of an unity equation for combined loads or stresses.
The testing was conducted by an independent, third-party, approved
test lab.
I would like to see the testing results conducted by Parametric and
the Suppliers Council that was conducted on the legacy shapes. I hear
the results would bring much interest from everyone in the industry
and further rock the aluminum industry.
The Pool Enclosure Collective is preparing to provide a seminar at the
next AAF Show in August for those interested in the Trac Beam and how
to use the testing results to design your pool enclosure to the
maximum efficiency. If any one has any questions or wants to be on the
attendees list for this seminar, please send me an email. We will also
be sharing testing results of purlins. Engineers will find it very
informative.

requesting them.
I would be happy to approval anyone that request to be a member of
this board or, if someone could send me an E-Mail list of people that
should or would like to join I will send them an invitation.
