Wrap or nothing?

Is it the front of the house, or as you stated, where the strap goes into the concrete?

It won't matter much as they won't get credit for re-nailing the deck as most of the nails missed the truss.

From a reliable source, the area where the strap enters the bond beam is considered the front.

Unless that rusty nail on the bottom is actually a nail, they are going to have to add one more to get the credit.
Again, we need to show both sides of the truss end.

Does anyone know what the exact uplift data is that the form is based on. By exact uplift data I mean what is the minimum Pounds per square foot (PSF) of uplift required.

I think this was recently discussed between Simpson the ARA and the OIR in the changing from 3 on front side to 2 on front side with one on back side ..thank you in advance

This was part of it.

Eric thanks-----Item says : Testing conducted by Simpson showed that 2+1 configuration is sufficient to produce resistance levels assumed in 2002 study.

Here is the study: http://www.rms.com/publications/RMS_...on_Credits.pdf

I looked through it very quickly but don't see an exact calculation (PSF) does anyone know what that is ?

By the way everyone should take a look at that study !

If you go back to the MSFH manual it would appear (pg83) the single wrap is rated at approximately 1000 lbs of uplift force. That comes from Simpson. The manual was developed using ARA studies.

Thanks Brian.....I guess the exact uplift calculation is conveniently left out.
