Vulnerability modellers toolkit, an open-source platform for vulnerability analysis

Vulnerability functions describe the expected loss for a given ground shaking intensity level and are an essential component in probabilistic seismic risk assessment. This manuscript presents novel open-source platform derivation of analytical fragility vulnerability models, covering state-of-the-art methodologies, addressing critical issues modelling such as uncertainty propagation, validation/verification results sufficiency/efficiency measure types. framework is divided into seven modules designed to guide users through different stages from selection motion records validation verification models. The was implemented Python programming language it freely accessible public GitHub repository. A graphical user interface included with toolkit intended be general-purpose method modellers interact (VMTK). Experienced encouraged use Python’s scripting capabilities explore all features VMTK source code contribute future releases toolkit.
