pystrata.propagation.EquivalentLinearCalculator¶

class pystrata.propagation.EquivalentLinearCalculator(strain_ratio=0.65, tolerance=0.01, max_iterations=15, strain_limit=0.05)[source]¶

Class for performing equivalent-linear elastic site response.

__init__(strain_ratio=0.65, tolerance=0.01, max_iterations=15, strain_limit=0.05)[source]¶

Initialize the class.

Parameters:

strain_ratio (float, default=0.65) – Ratio between the maximum strain and effective strain used to compute strain compatible properties.
tolerance (float, default=0.01) – Tolerance in the iterative properties, which would cause the iterative process to terminate.
max_iterations (int, default=15) – Maximum number of iterations to perform.
strain_limit (float, default=0.05) – Limit of strain in calculations. If this strain is exceed, the iterative calculation is ended.

Methods

`__init__`([strain_ratio, tolerance, ...])	Initialize the class.
`calc_accel_tf`(lin, lout)	Compute the acceleration transfer function.
`calc_strain_ratio`(mag)	Compute the effective strain ratio using Idriss and Sun (1992).
`calc_strain_tf`(lin, lout)	Compute the strain transfer function from lout to location_in.
`calc_stress_tf`(lin, lout, damped)	Compute the stress transfer function.
`wave_at_location`(loc)	Compute the wave field at specific location.
