Abstract
The land area of Indonesia has a geographical form of mountains and valleys. This condition is a challenge in the field of infrastructure development and development, so long bridges and high pillars must be built and must be able to withstand the risk of earthquake design. The construction of bridges in Indonesia, especially those built before the last standard applies, namely SNI 2833: 2016, so the bridge must be reviewed on its structure so that its security and handling ascertained. Every ground motion caused by an earthquake recorded so that an earthquake recording in the form of acceleration ground motion obtained. In this study, analysis and evaluation of bridge structures were carried out due to the influence of earthquake loads. The structure tested by the seismic load from seven data scaled ground motion acceleration records. The structural analysis uses a nonlinear time history analysis method. From the results of the non-linear time history analysis, it is proven that by scale adjustment of seven earthquake recordings with target spectrum responses, the scheme of plastic joints and the magnitude of damage caused by each earthquake have a different impact.
