The answer to the question on participation includes the following concepts:

For the sake of accuracy, here is a listing of the engineers that participated in the consensus process or provided very important and valuable contributions to Chapter 2.
Mr. Michael Kozlowski, P.E. Apex Technology
Mr. Tom Zgraggen, P.E. Aries Engineering, Inc.
Mr. Colin Bailey, P.E. Baily...
Sorry, I guess my comment was viewed out of line.
Just hope that everyone considers the work that has been done in this realm as work that has been the best work we can do at arriving at a consensus with the intention of good being done for the industry overall.

Probably good to re-read this post and actually read the material referenced in this post. The various responsibilities can get done professionally and the people responsbile for the various jobs can get paid for the professional work that they are doing if everyone desires that to be the...
If you want to undertake CLR design you can:
1) Use 2% of the max. axial compression force and accumulate it to a diagonal brace to the diaphragm or some type of bearing.
2) You can use BCSI B3 standard permanent bracing details.
3) You can use T, L or scab bracing of the web members.
4) You can...
Typically the the size, grade, and connection for continous lateral restraint (CLR) (laterals are not bracing diagonals are, fyi) are provided on the Truss Design Drawing for the web members that need a CLR (typically a 2x4 with 2 16d nails) along with the maximum axial compression force in the...
WTCA and TPI have worked very hard to define reasonable responsibilities for all parties involved in the construction process. The latest version of ANSI/TPI 1 Chapter “Responsibilities in the Design and Application of Metal Plate Connected Wood Trusses” can be found at this link --...
