Design Criteria for Engineers
I
have gathered design information from light gage stud criteria and the building
code for shear of 2” of concrete and then considered concrete tie beams and
rebar attachment to the slab.
Firstly: all information to compute the strengths of
the All Wall system is available and common knowledge to design structural
engineers.
Secondly: Following are safe allowable loads for up to
a two story home built to withstand the building code that is soon to be
adopted.
Wind
Perpendicular to the wall:
Less
than 50 psf will come from wind loading.
The All Wall system for 10’ tall wall section provides 85 psf.
All Wall -
Easily exceeds the requirements.
Shear
of a rebar into concrete is approximately 7,400 lbs less the concrete slab
reduction. 2,000 lbs is what is needed
for a 10’ tall wall with rebars on 4’ centers.
All Wall -
Easily exceeds the requirements.
Wind
Parallel to the wall:
The
All Wall system provides in excess of 2,235 PLF of shear plus the additional
shear of the columns.
2,235 PLF will exceed any two story home design.
Homes
will require, with the Highest winds by the code, probably 400 plf.
All Wall -
Easily exceeds the requirements.
To
determine the shear value use this formula:
2,235 PLF x undisturbed length of wall / total length of
wall
