1-At double stud locations where two pieces of plywood form a seam, stitch nail the two studs together with 16 ’ s 3 inches apart staggered. If the plywood collar is going to be 2 inches apart, nail them in concert 2 inches apart with 16 ’ second. If 6 inches, nail them 6 inches apart, etc .
Nail edge of each slice of plywood 3 ” aside staggered into each stud. For higher capacity shear walls edge nailing can be with 10d commons ( 0.148 ) tow inches on center. The affect of nailing on shear wall construction is discussed on this page about plywood complete.

The only way to by rights install a fleece wall is to snap a chalk line down the kernel of each stud and place a nail 1/4 inch from each side of chalk line. Remember, your shear rampart may be the alone thing between safety and catastrophe and it needs to be built perfectly .
2-On the ends, if there is a double stud for a clasp down, you can either stitch nail the two studs together 3″ o.c. and stagger nails 6″ o.c. on each dot ( this makes a full of 3″ o.c. nailing on this edge ) or nail into the end stud alone 3″ o.c. staggered .
3-In middle of plywood away from the edges put complete 12″ apart. Use a chalk line. No want to stagger .
4-Nail plywood to amphetamine top plate 3 inches apart. “ No indigence to nail into lower top plate. If there is an obstruction along upper top home plate, breeze through upper and lower top plates together with 16 ’ s 3 ” o.c. and pinpoint into lower circus tent plate only .
O.c. mentioned below means “ on center ” meaning center of one nail down to concentrate of the future collar. In bare terms o.c. means “ aside ” .

A coarse way of bridging breaks in a top plate is through the use of MST straps. Below is table representing their capacitance.

MST straps require 16d nails, though substitutions are allowed. For example, as shown in the alteration factor postpone below, if a 10d by 1-1/2 nails are used alternatively of a 16d commons, the strength of the strap must be reduced by 16 %. This is accomplished by multiplying the value in the postpone above by 0.84 .
therefore, an MST48 with a tension value of 5,310 pounds is actually worth 4,460 if 10d ticos are used ( 0.84 ten 5,310 ) .

high values can besides be achieved by using straps made of 2 by 4s. If the two top plates are nailed together to form one single penis, and the top plate rupture ( either single or doubled ) is bridged with a 2 by 4, the value of an MST48 can be achieved by installing 24 12d nails through the 2 by 4 on each side of the rupture. 5310/188=28.2 .
The value of a higher lastingness MST72 flog can be achieve with 36 nails on each side of the break- 6730/188 = 35.8 nails .
If staples are used, which have a fleece value of 80 pounds each and have no potential for separate, the capacity of this connections is about boundless .

narrow straps such as CS16 used in individual top plates have a a lot lower value

There is no decrease from using 10d nail 1-1/2 edge long quite than the 10ds in the catalogue.

This can be greatly increased with a wood 2 by 4 strap. If 20 nails are nailed through the 4 animal foot segment of 2×4 on each side of the break, the tension connection will now be worth 3,760 pounds. If 2 1/2 long staples are used, the capacity of this connection is about illimitable .
