RE: Hardy Frame, between code changes

[Subject Prev][Subject Next][Thread Prev][Thread Next]
There are pictures on his web site that show how the boxed frame installs
within the wall cavities. I'm not sure if it is designed as a braced strap
frame or uses a rigid compression and tension member - however, the diagonal
brace occurs in only one direction. The frame uses Simpson's PDH
Pre-Deflected holddowns for connection of the perimeter channels to the
foundation. I personally like these since they are easily installed with
screws. I have used them locally in both wood and light gauge steel framing
with desirable comments from the framers.

I suggest you visit the Hardy Frame web site for more information.

Here is some info taken from their web site on Hardy Frame:

It replaces the need for plywood in shear walls in both wood and
steel-framed construction
Light weight, high tensile galvanized steel, 98 to 160 pounds each
Shear strengths of 2,000 to 7,400 pounds, based on structural calculations
Dynamically tested to over 2 1/2 times calculated strength
Standard 8 and 9 foot heights to match stud walls (special sizes upon
Widths of 18", 32", 48", 64" and 80"
Sized to fit within 4" and 6" stud walls
Templates for all sizes to assure anchor bolt alignment
Standard bolts to footings and framing
Structural engineering calculations provided
Patent pending, No. P-5020
ICBO Report No. PFC-5342

Provides faster installation, greater design flexibility and more strength
than plywood.
Eliminates plywood, hold downs and posts, studs within the frame, nailing
schedules, special blocking and need for 3x plates.
Reduces inspection and waiting time.
Permits easy drywall, lathing and electrical installation.
Lowers overall cost!
One 848 Hardy Frame replaces four 1/2" sheets of plywood with nailing 4" on
center per L.A. City Code.

|	To add to the conundrum, I spoke with the SF building department,
|who at
|	this time are doing very little regarding the seismic issues related
|to the
|	SF version of the 97 UBC. If I understood correctly, they basically
|	until the state adopts the code this summer, then wait 180 days and
|	allow another 6 months grace period for printing (and reprinting
|	corrections). Then there is still the issue of SF amendments that
|	have language for exceptions as they relate to existing buildings.
|	engineer I spoke with said for all he knew the State Code could end
|	modifying the 2:1 aspect ratio that is in the 1997 UBC.
|	I spoke with Gary Hardy at Hardy Frame 1 800 754 3030 and he is
|sending me a
|	their info. ICBO report and a disk with their CAD details. As
|mentioned he
|	said that they are using their product in San Jose for about 200
|units. He
|	said that holdown uplift values are over 20kips.
