haz_fl_velo: Velocity-depth-damage functions from HAZUS, specific to flood

In hazus: Damage functions from FEMA's HAZUS software for use in modeling financial losses from natural disasters

Description

These functions are specified in HAZUS as empirical equations and indicate whether or not the structure will collapse under a given combination of flood velocity and flood depth. The empirical equations have the form specified below, where the coefficients and exponents are dependent on the velocity and depth thresholds for a given structure type

coef1 * V ^ {expo1} + coef2 * V + coef3

Format

Data frame with 8 columns and 12 rows

Details

Variables:

• num_story - Number of stories (1, 2 or 3)

• struc_type - Structure type (wood, masonry, concrete or steel)

• thresh_d - Depth threshold (ft) used in the above equation

• thresh_v - Velocity threshold (ft/s) used in the above equation

• coef1 - Coefficient in the above equation

• coef2 - Similar to coef1

• coef3 - Similar to coef1

• expo1 - Exponent in the above equation
