Information-theoretic development of a finite-wavelength-corrected ground-motion intensity measure for underground structures

The appropriate selection of ground-motion intensity measures (IMs) directly affects the reliability of probabilistic seismic demand models and fragility assessments for underground structures. To address the limitations of existing studies, which have primarily focused on screen...

An improved seismic fragility analysis framework with reduced dependence on predefined probabilistic demand-model assumptions

In Performance-Based Earthquake Engineering (PBEE), traditional seismic fragility assessments rely heavily on a priori statistical assumptions, such as log-normal distributions and homoscedasticity. These assumptions frequently fail to represent the profound heteroscedasticity an...
