Truss Analysis

A B C D E L S1y S1x S2 θ θ θ θ θ θ Assume forces in truss are as indicated. Then the forces at each node are as follows: At A: S1x – FAE FAB cosθ = 0 S1y FAB sinθ = 0 At B: FAB cosθ FBE cosθ FBC = 0 FAB sinθ + FBE sinθ = 0 At C: FBC + FCE cosθ FCD cosθ = 0 FCE sinθ + FCD sinθ = 0 At D: FDE + FCD cosθ = 0 S2 – FCD sinθ = 0 At E: FAE – FDE + FBE cosθ FCE cosθ = 0 -FBE sinθ FCE sinθ L = 0 Then these equations can be put into matrix form as:
