HH_Param#

class PySeismoSoil.class_parameters.HH_Param(param_dict: dict[str, float])[source]#

Bases: Parameter

Class implementation of the HH model parameters. After initialization, you can access/modify individual parameter values just like a dictionary.

Parameters:

param_dict (dict[str, float]) –

Values of the HH model parameters. Acceptable key names are:: gamma_t, a, gamma_ref, beta, s, Gmax, mu, Tmax, d

data#

HH model parameters with the keys listed above.

Type:: dict[str, float]

allowable_keys#

Valid parameter names of the HH model.

Type:: set[str]

items() → a set-like object providing a view on D's items#

keys() → a set-like object providing a view on D's keys#

plot_curves(figsize: tuple[float, float] = None, dpi: float = 100, **kwargs_to_matplotlib: dict[Any, Any]) → tuple[matplotlib.figure.Figure, list[matplotlib.axes._axes.Axes]]#

Plot G/Gmax and damping curves from the model parameters

Parameters:

figsize (tuple[float, float]) – Figure size in inches, as a tuple of two numbers. If None, use (3, 6).
dpi (float) – Figure resolution. If None, use 100.
**kwargs_to_matplotlib (dict[Any, Any]) – Keyword arguments to be passed to matplotlib.pyplot.plot().

Returns:

fig (Figure) – The figure object.
ax (list[Axes]) – A list of two axes objects.

pop(k[, d]) → v, remove specified key and return the corresponding value.#: If key is not found, d is returned if given, otherwise KeyError is raised.

popitem() → (k, v), remove and return some (key, value) pair#: as a 2-tuple; but raise KeyError if D is empty.

serialize() → ndarray[source]#: Return an array of parameter values in the order of: {‘gamma_t’, ‘a’, ‘gamma_ref’, ‘beta’, ‘s’, ‘Gmax’, ‘mu’, ‘Tmax’, ‘d’}

setdefault(k[, d]) → D.get(k,d), also set D[k]=d if k not in D#
