4. Select the Start Point indicated in the image above. This is the point where the left side
of the knee wall intersects with the top chord. The highlighted prompt changes:
Uniform load end location?.
5. Select the End Point noted in the image above.
6. The Triangulated Load appears on the Loading Diagram and the Uniform Loads dialog
box opens.
7. Select the Done button to close the dialog box.
Step 4
The last load to be calculated and added is the Uniform Load from the bottom chord (ceiling)
and the overhang of the 8'0" trusses that are supported by the knee walls. The elevation view
shown at the beginning of this lesson will help you better understand where the loads
originated. Using the following given loads and equations we can calculate the load to be
applied.
Top Chord Live Load = 20 PSF
Top Chord Dead Load = 10 PSF
Bottom Chord Dead Load = 10 PSF
Overhang Soffit Load = 2 PSF
