It calculates pile-head stiffnesses according to ANNEX-C of EC1998-5

It calculates pile-head stiffnesses according to ANNEX-C of EC1998-5 table C.1 with soil type E=Es (third row in table) for KHH, KMM, KHM. Last relation for KVV is calculated with Hooke relationship: Pl piLG KVV = --- = ------- w 2 starting from relationship according to Lancellotta's book "Fondazioni": 2Pl w = ------ piL*G Args: Es (float): Young modulus for terrain [MPa] Ep (float): Young modulus for pile material [MPa] D (float): Pile diameter [m] L (float): Pile lenght [m]

Returns:

Type	Description
float	Tuple with size 4, with horizontal stiffnesses KHH, flexural KMM,
float	cross KHM = KMH, vertical KVV gived by [KHH, KMM, KHM, KVV].
float	Dimension are [N/m] for translational springs and [N*m/rad] for
float	rotational springs.
