Problem 9.4d : Stadium Roof, I

  • Force P = 600 N
  • Force Q = 900 N
  • Force R = 1200 N
  • Length a = 3 m
  • Length h = 10 m
  • Length H = 13 m

The above roof truss was built to support a stadium roof which protects bleachers underneath. The forces entered into the figure represent estimates of the external forces due to snow load which were assumed to be 50% higher than those ever experienced before the truss was built.

My solution
