mph-20 lbs. per sq. ft. curtain area
** 100 mph- 38 lbs. ft. curtain area
To use
above table:
Step
1- Select the line under the column
headed “Door Height in feet”
corresponding to the door selected.
Step 2-Determine the lintel loads on
the selected line under the
appropriate columns.
Step
3-Multiply the values shown by the
door opening width in feet plus two
feet (Addition two feet is the
normal overlap) to determine the
lintel loads (Horizontal and
Vertical). These figures are the
live loads uniformly distributed
along the lintel where the curtain
is attached. The resulting
calculations are the live lintel
loads both vertical and horizontal
except as noted below.
Note:
The
calculated figures in step 3 are the
extra load factors to be used in
addition to the static and live
loads of the building itself.
These
figures are based on standard
installation instructions and could
be higher on non-standard
installation or unusual building
conditions. |
