Good morning class. My name is Jordan Lucas, and today we’re going to talk about the stage-damage relationship, otherwise known as the consequence function, and how it’s derived in HEC-FDA 2.0.
Explore various aspects of risk assessment in building asset valuation and damage prediction, covering topics such as stage-damage relationships, risk equations, sources of uncertainty, and first floor elevation considerations. Gain insights into the complexities of assessing and mitigating risks in property valuation and disaster planning.
