This is a linear combination of the mass and the stiffness matrices, where [alpha] is the mass damping coefficient, [beta] is the stiffness damping coefficient and [gamma] is the numerical damping coefficient.
In this setup, the damping coefficient was estimated from either the time response after a step unloading (pylon alone) or from the oscillation decay following a manually induced oscillation (pylon-foot assembly).
