Fourth Load Case (Steeple 4)
The fourth load case accounts for the maximum unbalanced wind load with snow left to right
that is perpendicular to the ridge. In our example, the 1400 and -1000 pound concentrated
loads shown below have been calculated to reflect these loads. Notice that the snow load is
only applied to the top chord from the left end to the peak. Use the same steps as the first load
case, add the point loads. Remember to Set the Current load case field to "Steeple 4" before
beginning.
