Where
1 = external virtual unit load acting on the beam in the stated direction of A.
m = internal virtual moment in the beam/frame, expressed as a f(x) and caused by the external virtual
unit load.
A = external displacement of the point caused by the real loads acting on the beam/frame.
M = internal moment in the beam/frame, expressed as f(x) and caused by real loads.
E = modulus of elasticity
I = moment of inertia of the CSA about the neutral axis
