Analysis of bridge structure with non-linear time history method

Bridges in Indonesia, which built before the last standard SNI 2833:2016 was issued, need to be reviewed to ensure the safety against earthquakes. This study employs non-linear time history analysis as method to analyze and evaluate the bridge structure due to earthquake loads. The structure undergoes a test with earthquake loads from seven records of scaled acceleration ground motion. From the analysis result, scale adjustment of seven earthquakes records towards the target spectrum response demonstrates various effects on plastic joints scheme and earthquake damage values. The evaluation result based on Cisomang highway/toll-bridge analysis denotes that Response modification factor value (R) is within the limit of permitted value of SNI 2833:2016 standard.
