Fragility functions vulnerability
WebKeywords: fragility, vulnerability, analytical methodologies, loss assessment 1. INTRODUCTION Fragility functions, a fundamental component in the process of assessing seismic risk, can be defined as the probability of exceeding a set of limit states, given a certain level of ground motion. http://www.sparisk.com/pubs/Porter-2007-deriving-fragility.pdf
Fragility functions vulnerability
Did you know?
WebFragility functions are commonly used to estimate the vulnerability of bridges subject to hazards. A fragility is defined as the conditional probability of attaining or exceeding a specified performance level given a (set of) hazard intensity measure (s). The development of the fragility functions for bridges has been the subject of much research.

There are almost 50 years of research on fragility and vulnerability assessment, both key elements in seismic risk or loss estimation.
WebFragility curves define the relationship between the probability of exceeding a particular damage state (or performance) of an infrastructure component, and the intensity of the applied hazard, whereas vulnerability curves define the relationship between expected losses (such as economic losses) and this same intensity. WebBuilding-specific fragility and vulnerability curves are derived for the three school buildings based on 3D incremental dynamic analysis (IDA) of the calibrated numerical models. The...
WebVulnerability functions gives the probability of the losses given a level of ground motion and the fragility functions gives the probability of exceeding different limit states (such as damage or injury levels) given a level of ground motions. Fragility curves are one of the important procedures of seismic risk assessment.
