Description

Nielsonandamp;DesRoches2007 USA Seismic Hazard: 48 artificial accelerograms $Paragraph$Exposure: 8 schematic bridges typical for central and southeastern United States. $Paragraph$ $Paragraph$Variation of concrete, steel and bearing properties, foundation stiffness, deck mass, damping ratio and gaps are considered in the analyses. $Paragraph$ $Paragraph$The fragility curves for single column, bearing and abutments are also analyzed in the paper. $Paragraph$The fragility curves for upper bound and lower bound of the bridges are also provided in the paper. $Paragraph$This study shows that the bridge as a system is more fragile than any one of the individual components. Fragility parameters: Medians=[0.235, 0.704, 1.025, 1.458], Standard deviations=[0.17, 0.511, 0.743, 1.057] Syner-G taxonomy: MM1= MM2= TD1= TD2= DC= DSS= PDC= TC1= NP= TS1= TS2= HP= Sp= SC=None TCa= BC= LS= Taxonomy link: https://publications.jrc.ec.europa.eu/repository/bitstream/JRC80560/lbna25883enn.pdf
