The total load in force units on the joist equals the tributary area area units times the uniform pressure loading force per unit area.
Floor area at shear walls.
Floor joist tributary area.
It s dimension transverse to the joist is half the distance to the next joist on either side also known as the tributary width and it s length is the length of the joist.
Under prescriptive design codes for conventional construction shear walls are referred to as braced wall panels.
Shear walls are wall systems that transfer lateral wind and seismic loads from a roof or floor down to lower levels and then into the foundation.
Stiffness of wall solution.
The term diaphragm is usually applied to roofs and floors.
A shear wall however is a vertical cantilevered diaphragm.
A significant decrease in displacement with increasing shear wall area to floor area ratios between 1 2 x 0 7 y and 1 47 x 0 85 y is observed which indicates that at least 1 2 x 0 7 y of shear wall ratio should be used in design.

Flanged shear wall net area net moment of inertia.
The most common and useful practice of the shear wall is in the center lift section or in the parameter of the building.
2 on the ends if there is a double stud for a hold down you can either stitch nail the two studs together 3 o c.
Specifically the ibc irc wfcm and icc 600 provide prescriptive shear wall details and designs that may be applied when certain basic conditions are met.
A diaphragm structure results when a series of such vertical and horizontal diaphragms are properly tied together to form a structural unit.
The lateral force experienced by the structure.
0 75 times floor to floor wall height analysis.
On each stud this makes a total of 3 o c.
The location of the shear wall totally depends on the structure plan.
Table 2304 6 of the 2006 ibc lists the minimum thickness of wall sheathing and.
It is very difficult to find the best location for this wall.
Shear walls 8 40in.
Determine stiffness from basic principles.

Distinction between 6t and 0 75 times floor to floor wall.
A diaphragm is a flat structural unit acting like a deep thin beam.
And stagger nails 6 o c.
Nailing on this edge or nail into the.
Constructed with adequate floor and roof diaphragms and shear walls.
Remember your shear wall may be the only thing between safety and catastrophe and it needs to be built perfectly.
Shear walls 1 load distribution to shear walls shear wall stiffness.
Fully grouted shear wall required.
