Do tension resistant strappings count as "allowable loads", as specified in Simpson Strong Tie Catalogs?

Question

Example;

16 ga; 3" wide, 52" long MSTC40 w/52-16d sinkers has allowable loads of 4335, 4585, & 3745, 4495.

The assembly requires 1/2 of specified nails at each end of strap anchored parallel to the depth of the strap and perpendicular to the anchoraging material, Douglas Fir Larch/Spruce Pine wood.

Question;

Do all tension-resistant strappings add resistance, or "allowable loads", as long as the end connections and anchoragings are strong enough and shear-resistant enough to maintain the tension-resistant strap's location when stressed on?

Answer 1

These strap assemblies (I have the simpson catalog open to the very strap you have mentioned) can resist the loads as listed provided the connections are made with all the 16d sinkers required, and that the lumber to which you are connecting is DF or SP species.  The loads are listed as allowable but with the 133 and 160 percent factors already applied for earthquake and wind forces respectively.

Also you should read the general notes information on page 13 (in my catalog C-2007).

You should read the footnotes on the sheet where the strap is called out.
