tcra.hazard.Cyclone module

The tcra fragility_rehab module contains function to perform physical damage using existing fragility curves for building archetypes.

class CycloneParameters

Bases: object

This is Damage Probability Analysis class. This class estimates probabilities of various damage states.

__init__(data)

calculate_wind_speeds(df_track, blg)

Estimate wind speed at structure site.

Parameters:

• df_track – Cyclone track with estimated parameter based on estimate_parameters function

• blg – building inventory

Returns:

• Vmph – wind speed (mph)

• bldg_wind – building inventory with estimated wind speed

• VG – gradient wind speed.

estimate_parameters()

Estimate cylone (i.e., hurricane) hazard parameters.

Parameters:

• Lat – Latitude

• Long – Longitude

• CP – Central Pressure (millibar)

Returns:

• Δp – Central Pressure Difference (millibar)

• Rmax – Radius to max wind speed (km)

• B – Holland Parameter

• ρ – Air density

• Ω – Earth’s angular velocity (rad/s)
