merge_curve_matrices#

PySeismoSoil.helper_generic.merge_curve_matrices(GGmax_matrix: ndarray, xi_matrix: ndarray) → ndarray[source]#

Merge G/Gmax curves matrix and damping curves matrix. Both matrices need to have the following format:

strain [%]

G/Gmax

strain [%]

damping [%]

strain [%]

G/Gmax

…

…

They need to have the same shape. This function will take the G/Gmax information from GGmax_matrix and the damping information from xi_matrix, and produce a new matrix.

Parameters:

  • GGmax_matrix (np.ndarray) – A 2D numpy array of the format above that contains G/Gmax information.

  • xi_matrix (np.ndarray) – A 2D numpy array of the format above that contains damping information.

Returns:

merged – The merged 2D numpy array.

Return type:

np.ndarray

Raises:

ValueError – When the input has invalid values
