16 Gage Staples 5

[BSVBD]

I'm being asked to design a mini-storage structure with the same shearwalls as the previous structure for which existing plans are provided to me.

The problem i have is that the shear walls are designed with 1-1/2" x 16 gage staples instead of nails. The ANSI / AF&PA SDPWS-2008 does not provide load tables for staples that i can see. I believe i've seen older load tables for such a design, but, i cannot locate them at this time.

Is anyone familiar with wood shearwall load tables with 1-1/2" x 16 gage staples?

Thank you!

1) Check out the linked fastener guide by Bostitch.

2) Call Bostitch if you don't find what you need. They'll know for sure.

I've used staples for shear walls before but don't remember the details wrt to code reports etc.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

The tables are in the IBC chapter 23. For 2012 it's Table 2306.3(1) and it specifically lists 1 1/2" x 16 gage staples.

Thank you both!

I wonder why ANSI / AF&PA doesn't have staples if IBC does?

Mike, for what it's worth, i tried multiple times to give you a star, but, "the system" won't do it. I'll try again tomorrow.

Done. Instant gratification is an important part of pro-bono consulting.

ESR-1539 Also will have staples for Diaphragm and Shearwall Values. Bostitch is a listed in ESR-1539.

The following tables are taken from ESR-1539, Bostitch and IBC, respectively.

How can i justify using the ESR-1539 which (apparently) has an allowable 260 PLF, while Bostitch and IBC list an allowable 185.

What am i misunderstanding?

Thank you!

See IBC2306.3 - You can increase the IBC values by 40% for wind design. The ESR just lists the wind and seismic separately similar to NDS and includes the extra 40% in the table.

Next question:

Why do you suppose ANSI / AF&PA SDPWS-2008 does not provide load tables for staples?

Also, why do they state the 40% allowable increase? - At least not that i can see - am i missing something there also?

 

[RWW0002]

I do not think AF&PA NDS or SDPWS cover staples at all. IBC steps in and includes some data, but we must mostly rely on ICC report data otherwise.

My understanding of the 40% factor has to do with a factor of safety of 2.0 for wind and 2.8 for seismic (for ASD).

Woodworks has some good papers and presentations on the design and background of diaphragms and shear walls that might be worth checking out.
