Shear Wall Nailing

Wooden framing with vertical studs and sheathing. Stiffness in shear walls is also a function of nailing.

8 Tips And Tricks On Effective Shear Wall Construction

Nailing For Structural Shear Wall Panels Per Structural Plans.

Shear wall nailing. Must be adjusted by a reduction or resistance factor. Shear walls nailing is a huge part of shear wall construction which can be very different from framing walls such as load bearing wall or non-bearing wall. It will specify both edge nailing and field nailing.

The wood frame with vertical studs alone is subject to deformation and collapse and so the frame is covered in sheathing typically plywood or oriented strand board OSB. The tables below show the shear wall specification for the walls in the example in a typical format. The only way to properly install a shear wall is to snap a chalk line down the center of each stud and place a nail 14 inch from each side of chalk line.

The impact of nailing on shear wall construction is discussed on this page about plywood nailing. Maintain a minimum of 38-inch from plywood panel edges to minimize plywood tear out. 4 or 6 OC.

Shear Wall Plywood Nailing And Structural Issues Framing. This creates a potential for overturning which must be accounted for and any over-turning force is typically resisted by hold-downs or tie-downs at each end of the shear element. This assures that it remains rigid even under lateral pressure.

A shear wall is simply a cantilevered diaphragm to which load is applied at the top of the wall and is transmitted out along the bottom of the wall. Nailing and stiffness are important factors in how much earthquake force a shear wall can resist. WSP Combined Shear Uplift 20 SHEAR WALL -TYPES Individual Full-Height Wall Segments No openings within individual full-height segments Force Transfer Shear Walls With openings but framing members blocking and connections around openings are designed for force-transfer Perforated Shear Walls With openings but reduced shear.

A shear wall nailing deputy inspection involves verification of the nail size and spacing lumber and sheathing type size thickness and any hardware attachments for that specific shear wall such as anchor bolts hold downs A35s etc. Can also use horizontal and diagonal board sheathing gypsum panels fiberboard lath and plaster and others Blocked shear walls most common. The closer the nails are spaced on the edge of the plywood the stiffer the shear wall.

Note that they do not include some detailing that is required for items such as the uniform uplift force on the bottom plate of all perforated shear walls or the perforated shear. Table 43A in SDPWS gives a nominal unit shear capacity of 515 plf 560 plf times 092 for DF to SPF reduction for a 3 8 WSP shear wall with 6d common 2 x 0113 nails. For example 612 means nails are spaced every 6 inches on-center along edges and boundaries edges of windows and doors and every 12 inches along intermediate studs.

This is comparable to the median shear capacity for the shear walls with 8d galvanized box 2- 3 8 x 0113 nails. We are insured and fully ICC International Code Council and local jurisdiction certified to provide services in all of Southern California including. This is the most common form of shear wall in US buildings.

Studying the important components that make up the walls for shear resistant is an important step to framing walls correctly. Unless specifically designed in accordance with Item 1 above sill plates under nonbearing interior partitions on concrete floor slabs shall be anchored at not more than four 4 feet 1219 mm on center to resist a minimum allowable stress shear of 100 pounds per linear foot 14 kNm acting either parallel or perpendicular to the wall. Stagger all nails at plywood panel edge.

This understanding of walls to resist shear. Maintain a minimum of 38-inch from plywood panel edges to minimize plywood tear out. No project is too small.

All items should be in conformance with the shear wall schedule on the approved plans. If the stepped foundation is. Sheathed shear walls most common.

Shear Wall Plywood Nailing And Structural Issues Framing. For higher aspect ratio shear walls the post size and holdown type may significantly reduce the moment arm between center of tension and center of compression resulting in higher tension and compression forces. Our team offers field experienced and certified specialdeputy inspectors in multiple areas including concrete placement shear wall nailing epoxy and anchor torque testing.

The shear wall schedule provided by the designer or engineer typically includes nail size and spacing. Wall Sheathing Installation Tips from Georgia-Pacific - YouTube. Space panel edges 18 inch.

Remember your shear wall may be the only thing between safety and catastrophe and it needs to be built perfectly. Patent Us20080209749 In Situ Shear Wall Nailing Template. SDPWS has reduction factors for unblocked shear walls Note that capacities are given as nominal.

We provide service in both residential and commercial buildings.
