Scalar and vector-valued fragility analysis of typical Algerian RC bridge piers
This paper presents and discusses an approach for performing scalar and vector vulnerability assessments of typical Algerian RC bridge piers. Across incremental dynamic analysis, the seismic response was calculated while considering 60 seismic ground motions and 10 intensity measures (IMs). An optim...

| description | This paper presents and discusses an approach for performing scalar and vector vulnerability assessments of typical Algerian RC bridge piers. Across incremental dynamic analysis, the seismic response was calculated while considering 60 seismic ground motions and 10 intensity measures (IMs). An optimal scalar-valued IM was assessed and selected through regression analyses. It was validated based on several metrics including the correlation, efficiency, practicality, and proficiency. The fragility of vector-valued functions that use two pairs of IMs were calculated and compared with fragility curves based on scalars. The comparison indicated that the damage probability can be underestimated or overestimated in vulnerability analysis. |
