Step 3
Calculate the triangulated Load resulting from the dormer knee wall and apply that load to the
girder. The knee wall varies in height from 0'0" at the start point to 8'0" at the end point (see
below).
The triangulated Load is calculated to be 0.0 PLF at the Start Point and 110 PLF at the End Point.
110 PLF is arrived at by multiplying the height of the wall, 8'0" at the end point by 13.75 PSF.
1. Select the Add Uniform Loads icon from the Loading Toolbar, to access the Uniform
Loads dialog box.
2. Set the fields as shown
3. Select the Apply button. The highlighted prompt at the bottom of the screen indicates
the next step: Uniform load start location?.
