Ventura] BEng | Universisdad Popular Autonoma del Estado de Puebla, Mexico (2012) MASc Student | The University of British Columbia, Canada ( Present) The 5 th Tongji-UBC Symposium on Earthquake Engineering “Facing Earthquake Challenges Together” May , Tongji University Shanghai, China

Napa River Bride Background Information Built in Spans Precast girder on flexible 2 column piers and 4 column piers. 2

Background Information 1989 Loma Prieta Earthquake repairs were conducted 1996 an extensively retrofit was implemented ◦ Bolsters and transverse prestressing to the end of the diaphragm ◦ Expansion joints retrofit ◦ Additional piles and large pilecaps ◦ Columns incase in steel jackets 3

Background Information 2001 A strong motion is installed to the bridge with 12 accelerometers on bridge and 3 at free field site. 4

Background Information 5

2014 Napa Earthquake M6.0 Earthquake south of the city of Napa 6

Recorded Data, Transverse Direction The evaluation of the record in the transverse direction Channels 1,5,6,7,9and11 were analyzed respectively 7

Record Evaluation Acceleration 8

Record Evaluation Velocity 9

Record Evaluation Displacement 10

Recorded Data, Longitudinal Direction The evaluation of the record in the logitudinal direction Channels 3,8and12 were analyzed respectively 11

Record Evaluation Acceleration 12

Record Evaluation Velocity 13

Record Evaluation Displacement 14

Recorded Data, Vertical Direction The evaluation of the record in the vertical direction Channels 2,4 and10 were analyzed respectively 15

Record Evaluation Acceleration 16

Record Evaluation Velocity 17

Record Evaluation Displacement 18

Fourier Amplitude 19

Pier Behavior 20 Channel 1 and 2Channel 4 and 5

Bridge Damage 21 A PEER assessment was conducted to the bridge

Bridge Damage 22

Conclusions 23 Record evaluation can provide a quick assessment of the bridge after an earthquake. It can provide to understand the dynamic behavior of the bridge as a whole and in some specific structural elements An ambient vibration test is necessary to have a better understanding of the bridge.
