Seismic Fragility Analysis
Damage probability matrix; Fragility curve; Fragility surface; Limit state; Numerical simulation; Seismic capacity; Seismic demand; Uncertainty
Seismic fragility can be defined as the proneness of a structural component or a system to fail to perform satisfactorily under a predefined limit state when subjected to an extensive range of seismic action. In accordance with the above definition, seismic fragility analysis can be regarded as a probabilistic measure for seismic performance assessment of structural components or systems. There are two different end products of seismic fragility analysis: damage probability matrix and fragility curve.
Damage probability matrix (DPM) is a table that provides discrete values of damage state probabilities for specified levels of ground motion intensities. Each column of DPM stands for a constant level of ground motion intensity whereas each row of DPM denotes the probability of being in a predefined damage state. Hence, any...
