End Anchor Foundation Tube Thickness
Question
State
OH
Description Text
Is it acceptable to use 1/8” thick foundation tubes in the trailing end anchorage for the MGS versus the 3/16” tube that we have typically tested with in the past.

I spoke with designers of the FLEAT and SKT systems. They indicated that they have tested the wood post versions of those terminals with the MGS using the thinner foundation tube. It is likely that the 1/8” tubes that you have originated from this work. The 1/8” thick tubes performed acceptably in their testing, which would indicate that they would be acceptable for the trailing end anchorage as well. The 1/8” tubes would also have a higher section modulus than many of the proprietary steel post end terminal anchorages that rely on the weak action section modulus of W section posts to develop anchorage. Thus, we believe that the 1/8” thick tubes are acceptable.
Thanks
