Shear Wall System

The strength, stiffness and ductility of the MiTek Lateral System enables architectural design that maximizes window and door openings without compromising structural integrity.

LEADING IN LATERAL

SHEAR WALL SYSTEM

The Shear Wall System is the leading pre-fabricated shear wall in the residential and multi-family building industry. The strength, stiffness and ductility of the MiTek Lateral System enable architectural design without compromising the structural integrity.

The Shear Wall System is made up of the Hardy Shear Wall Panel and the Hardy Brace Frame.

Increase the Effective Sections

The Hardy Shear Wall Panel comes in widths of 9”, 12”, 15”, 18”, 21” and 24”. The 9” through 18” widths are a one-piece C-Section that is enclosed at the top and bottom with channels.

The 21” and 24” wide Panel differs from the other widths by the addition of two “Z” shapes, welded inside the one-piece C-Section, forming a post at each Panel end. The inclusion of posts serves to increase the effective section while decreasing the effective, unsupported Panel width.

Resist Lateral Loads in Both Tension and Compression

Hardy Brace Frames are a rectangular shape with a single diagonal member, which resists lateral loads in both tension and compression.

The two vertical end posts and the diagonal member are rectangular, tube shapes. The vertical and diagonal members are capped at the top and bottom with channels that mirror each other with a stamped hole pattern to hold down anchors and screws, along with a non-structural “field” for attaching surface finishes.

HARDY SHEAR PANEL SPECS


Shear Wall Panel on Concrete Foundation

  • Installation on nuts and washers provides for leveling at uneven concrete – and an open end box wrench may be used to secure connection from below. Allowable loads are less than installation directly on concrete. Confirm with design building professional prior to installation.
  • Raised floor head out installations bypass wood framing to eliminate the effects of shrinkage and crushing, while providing a direct shear transfer to the foundation

Shear Wall Panel on Wood Sill Plate

  • Panels installed on wood sill plates have more ductility but, for some sizes the allowable shear is less to account for crushing of wood below
  • Allowable values have been reduced when necessary to maintain code drift limit (see HFX-Series Product Catalog Table 1.2)

Installation:

  • Set bolts 4-1/4″ inches above concrete
  • Moisture barrier (15# felt, Moist Stop, Etc.) recommended when installing on treated wood

Shear Wall Panel on Raised Floor

  • Allowable values have been reduced when necessary to maintain code drift limit (see HFX-Series Product Catalog Table 1.3)
  • Table values for Panels installed on a wood floor system assume installation with a Hardy Bearing Plate

Installation at raised floor head-out:

  • Provides allowable values from HFX-Series Product Catalog Table 1.2A
  • Provides a direct shear transfer to the foundation
  • Requires less material by eliminating rim, Bearing Plate and bottom screw

Shear Wall Panel on Upper Floor

  • Allowable values in Table 1.3A have been adjusted to maintain code drift limit while including the effects of crushing in wood members below.
  • For “straight stack” installations, cumulative forces must be considered by the building design professional.
  • For discontinuous systems, amplification factors must be considered by the Building Design Professional.
  • Table values for Panels installed on a wood floor system assume installation of a Hardy Bearing Plate.
  • For installations on beams, size plate washers on underside of wood beam to prevent crushing and include deflection from the overturning couple in the drift procedure.

Shear Panel Cold Formed Steel Framing

  • HFX/S Series products are manufactured to cold formed steel stud heights. Nominal 8′ heights are 96 5/8″ net, nominal 9′ is 108 5/8″ etc.
  • Installation can be directly on concrete (moisture barrier recommmended), with a c-fs channel below, on a nut and washer for levelingor height adjustment up to ±1-1/2″ when approved by the Building Design Professional
  • Top connections are made with 1/4″ diameter self tapping screws after installing floor or roof members above
  • Panels are 3-1/2″ net depth

HARDY BRACE FRAME SPECS


Brace Frame on Concrete Foundations

  • Installation on nuts and washers provides for leveling at uneven concrete – open end box wrench may be used to secure connection from below. Confirm with design building professional prior to installation.
  • Raised floor head out by passes wood framing to eliminate the effects of shrinkage and crushing, while providing a direct shear transfer to the foundation
  • Raised floor head out requires less material by eliminating the rim and bottom screws
  • The new HFX-Series Brace Frame has relocated hold down bolts to be outside of the post. Hold down connections are now accessible even when wood or framing is incontact with the edge of the frame

Brace Frame on Wood Sill

  • Brace Frames installed on wood sill plates have more ductility but, for some sizes the allowable shear is less to account for crushing of wood below
  • Allowable values have been reduced when necessary to maintain code drift limit (see HFX-Series Product Catalog Table 1.2)
  • Because the Brace Frame base is wider, overturning forces cause less compression on wood sill.

Installation:

  • Set bolts 4-1/4″ inches above concrete
  • Moisture barrier (15# felt, Moist Stop, Etc.) recommended when installing on treated wood

Brace Frame on Raised Floor

  • Allowable values have been reduced when necessary to maintain code drift limit (see HFX-Series Product Catalog Table 1.3)
  • Raised floor head out installations by pass wood framing to eliminate the effects of shrinkage and crushing, while providing a direct shear transfer to the foundation
  • Table values for Panels installed on a wood floor system assume installation with a MiTek Hardy Bearing Plate

Installation at raised floor head-out:

  • Provides allowable values from HFX-Series Product Catalog Table 1.2A
  • Provides a direct shear transfer to the foundation
  • Requires less material by eliminating rim, Bearing Plate and bottom screw

Brace Frame on Upper Floor

  • Allowable values in HFX-Series Product Catalog Table 1.3A have been adjusted to maintain code drift limit while including the effects of crushing in wood members below
  • For “straight stack” installations cumulative forces must be considered by the building design professional
  • For discontinuous systems amplification factors must be considered by the building design professional
  • For installation on beams, size plate washers on underside of wood beam to prevent crushing and include deflection from the overturning couple in the drift procedure
  • Because Brace Frames are wider, overturning forces cause less compression on wood below and shrinkage has less effect on horizontal drift.
  • Unlike Panels, Brace Frames install on the bottom plate above floor systems. MiTek Hardy Bearing Plates are not necessary.

Cold Formed Steel (cs-f) Framing

  • HFX/S Series products are manufactured to cold formed steel stud heights. Nominal 8’ heights are 96 5/8˝ net, nominal 9’ is 108 5/8˝ , etc.
  • Installation can be directly on concrete (moisture barrier recommended), with a c-fs channel below, or a nut and washer for eveling or height adjustment up to ± 1/2˝
  • Top connections are made with 1/4˝ diameter self tapping screws after installing floor or roof members above.
  • Brace Frames are 3 1/2˝ net depth.
  • The new HFX-Series Brace Frame has relocated hold down bolts to be outside of the post. Hold down connections are now accessible even when wood or framing is in contact with the edge of the frame.
