tsnet.network.control module

This file to define Fragility Curves

class tsnet.network.control.FragilityCurve

Bases: object

Fragility Curve class.

add_state(name, priority=0, distribution={})

Add a damage state distribution

Parameters:

• name (string) – Name of the damage state
• priority (int) – Damage state priority
• distribution (dict, key = string, value = scipy.stats statistical function) – ‘Default’ can be used to specificy all location

states()

A generator to iterate over all states, in order of priority :returns: :rtype: state_name, state

get_priority_map()

Returns a dictonary of state name and priority number.

cdf_probability(x)

Return the CDF probability for each state, based on the value of x

Parameters:x (pd.Series) – Control variable for each element Returns:Pr – Probability of exceeding a damage state Return type:pd.Dataframe

sample_damage_state(Pr)

Sample the damage state using a uniform random variable

Parameters

Pr : pd.Dataframe

Probability of exceeding a damage state

Returns:damage_state – The damage state of each element Return type:pd.Series

class tsnet.network.control.State(name, priority=0.0, distribution={})

Bases: object

Parameters:

• name (string) – Name of the damage state
• priority (int) –
• distribution (dict) –

tsnet.network.control.plot_fragility_curve(FC, fill=True, key='Default', title='Fragility curve', xmin=0, xmax=250, npoints=100, xlabel='x', ylabel='Prob. of exceedance', figsize=[10, 6])

Plot fragility curve.

Parameters:

• FC (FragilityCurve object) – Fragility curve

• xmax (float (optional)) – X axis maximum (default = 1)
• npoints (int (optional)) – Number of points (default = 100)
• xlabel (string (optional)) – X axis label (default = ‘x’)
• ylabel (string (optional)) – Y axis label (default = ‘Probability of exceedance’)
• figsize (list (optional)) – Figure size (default = [10,5])
