(Revised: 03/17/21)
The Parapet tab is
used to locate and define Parapets.
General comments:
·
Parapet geometry defined on this screen will not be lost if the building
geometry is redefined.
·
Note: If the Predefined or Custom
Shape is revised to a different shape, then all located and defined parapets
will be lost.
Parapets
can be located full span or partial span, dimensioned from the edge of a wall
or from any existing frame line.
Additional
adjustments for extending Parapets into Roof Extensions and skewing the corner
options are available.
Size:
Height
Software
will default to a minimum height of 1/2/0 greater than the sidewall eave height
or end wall ridge height and then rounded up to the nearest 12 inches to ensure
enough room for all trim conditions.
The
vertical height of the Parapet is defined as follow:
Parapets measured from the Finished Floor Elevation
to the Top Parapet Girt.
This is dimensioned to the outside of the secondary
steel structure, not to the outside of the panel or trim.
„
Notes:
Parapets with system generated framing must be
located on 8 1/2" outset walls with end frames located 1'-0" from the
endwall Building Line.
Verify that the rafter flange clears the parapet
posts. The maximum rafter flange is 7" at posts.
Parapets do not project from the walls.
Framing By Others

if the Parapet framing is Not by the Metal Building Manufacturer.
Any
column offset or frame offset is permitted when Parapet Framing by Others is

The
software will display the below warning with any non-standard endwall frame
location or any girt depth other than 8.5” with standard framing options.
The
below dialog will display if you don’t select the Framing by Others checkbox.
