Uniform and partial
load cases for roof
trusses in Example 5-1.
(A) Uniform loading.
(B) Partial load Case 1.
(C) Partial load Case 2.
Example 5-2 Partial Snow Load, Continuous
Purlins in Gable Roof (1 on 12)
Problem
Given the same conditions outlined in Example 4-1 for an emergency vehicle
storage garage, determine the partial loading on the purlins for the gable
roof building shown in
Figure G5-8.
Solution
The conditions are the same as those given in Example 4-1, so the balanced
roof snow load is 18.5 lb/ft
2
and the minimum roof snow load is 24 lb/ft
2
.
The problem statement does not ask for the controlling
uniform
roof snow
