Parametric Studies

Definition

Parametric studies involve the systematic variation of parameters in a model to understand their effects on the output or performance of a system. By changing one or more variables while keeping others constant, engineers can analyze how different design choices influence structural behavior, particularly in terms of ductility and resilience during seismic events.
