Analysis of bridge structure with non-linear time history method

Abstract

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.

Seismic Performance of Reinforced Concrete Bridge in Pan Borneo Highway Sarawak under the Influence of Seismic Loadings

“…Research was analyzed on a prestressed I girder bridge and determined that non-linear time history analysis effectively simulated the bridge's damage category under varying intensity levels of seismic loads [19]. Kamal and Gunadi [20] studied toll bridges and observed significant non-linear behavior in their seismic response.…”

Application of Modal Analysis of Earthquake Force and Natural Frequency Tanjung Baru Bridge

“…For instance, research conducted by Çubuk et al [14], Murdiansyah et al [15], and Zhang et al [16]. To investigate the earthquake load, earlier researchers in this field predominantly applied spectral response methods and employed analysis of time-histories as the study carried out by Kamal and Gunadi [17], Indulkas et al [18], and Hakim et al [19]. Therefore, the present study contributes to the existing literature by providing an improved understanding of how to apply a modal analysis for the analysis of earthquake load on a bridge.…”
