Floor Area At Shear Walls

A shear wall however is a vertical cantilevered diaphragm.

Floor area at shear walls.

The lateral force experienced by the structure. Centroid from outer flange in in in in in in in in y 11 16 671 7 62 48 3 81 7 62 40 20 2 example. The most common and useful practice of the shear wall is in the center lift section or in the parameter of the building. 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.

On each stud this makes a total of 3 o c. A diaphragm structure results when a series of such vertical and horizontal diaphragms are properly tied together to form a structural unit. And stagger nails 6 o c. Remember your shear wall may be the only thing between safety and catastrophe and it needs to be built perfectly.

Shear walls 8 40in. 0 75 times floor to floor wall height analysis. A diaphragm is a flat structural unit acting like a deep thin beam. Constructed with adequate floor and roof diaphragms and shear walls.

Floor joist tributary area. 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. Nailing on this edge or nail into the. Flanged shear wall net area net moment of inertia.

Under prescriptive design codes for conventional construction shear walls are referred to as braced wall panels. 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. Table 2304 6 of the 2006 ibc lists the minimum thickness of wall sheathing and. Distinction between 6t and 0 75 times floor to floor wall.

The location of the shear wall totally depends on the structure plan. It is very difficult to find the best location for this wall. The total load in force units on the joist equals the tributary area area units times the uniform pressure loading force per unit area. The location is decided after the complete structural analysis or case studies.

The hatched area is referred to as the tributary area for the joist. Determine stiffness from basic principles. Flanged shear wall net area net moment of inertia shear area shear walls 10 m. Stiffness of wall solution.

The shear wall area to floor area ratio also referred to as shear wall ratio the wall aspect ratio and the wall con figuration in plan are indicated as important parameters that affect the. 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. Fully grouted shear wall required.
