Description

SaxenaEtAl2000 USA Exposure: existing RC bridge, twelve-span continuous reinforced concrete bridge is selected for this study (Santa Clara Bridge). $Paragraph$Different variability curves are obtained when considering spatial variability of the ground motion. Five different cases of asynchronous support ground motion are considered as shown in the following table: $Paragraph$Case UBC Soil type II (medium) at Piers UBC Soil type III (soft) at Piers $Paragraph$1. DIFF Pier 1-4, Pier 8-11 Pier 5-7 $Paragraph$2. SAME-MEDIUM Pier 1-11 - $Paragraph$3. IDENT-MEDIUM Ground Motion at Pier 1 applied to all the other piers - $Paragraph$4. SAME-SOFT - Pier 1-11 $Paragraph$5 .IDENT-SOFT - Ground Motion at Pier 1 applied to all the other piers $Paragraph$Where: $Paragraph$i) DIFF: different supports are on different local soils $Paragraph$ii) SAME: all supports are on same local soils $Paragraph$iii) IDENT: for each set of differential support ground motion time histories, the corresponding set of identical support ground motion time histories is obtained by considering that the ground motion time history at the first support is applied to all the other supports Fragility parameters: Medians=[0.361, 0.502, 0.839], Standard deviations=[0.095, 0.134, 0.255] 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
