PROBLEM 2: The roof truss shown is supported on rollers at A and is hinged at B. The wind loads H1, H2, and H3, act
perpendicular to the top chord. Analyze the truss based on the stated conditions. Indicate “C” for compression and “T”
for tension.
Given:
S = 3.0 m
H = 1.5 m
Required:
1. Force in member DE (kN) due to the load, P = 105 kN.
Wind loads = 0 (Answer: 157.500 (T))
2. Force in member DE (kN). (Answer: 25.931 (T))
Given: H1 = 16 kN; H2 = 27 kN; H3 = 11 kN; P = 0
3. Force in member DE (kN). (Answer: 183.431 (T))
Given: H1 = 16 kN; H2 = 27 kN; H3 = 11 kN; P = 105 kN
