Since ψA = 0 and HA = 0
MA = LPM / AMM = Moment (Couple) at Left Node A
δHA = AHM MA - LPH = Horizontal Deflection at Left Node A
General reaction and deformation expressions with right end pinned
Loading Terms LPH and LPM are given below.
Reaction loads and moments VA and VB, and HB can be evaluated from equilibrium equations after calculating HA and MA.
