10. LOAD VECTOR
P = F – FEF
P is load vector
F is nodal force
FEF is the force observed at nodes due to
application of loading between nodal points
11. FORMULATION OF LOAD VECTORS
Frame members 1, 2, 3, 4, 7, 8, 9 and 12 have no
loading between nods so
As FEF is null matrix for local axis so for global
FEF will be
12. FORMULATION OF LOAD VECTORS
For member 5 and 6 FEF will be given by
following
13. FORMULATION OF LOAD VECTORS
For member 5 and 6
For transforming it in to global, transformation
matrix will be used
14. FORMULATION OF LOAD VECTORS
For member 5 and 6 θ = 0 degree
FEF will be given by
Which is
