Abstract

The cable-stayed bridges are vulnerable to vibrations caused by earthquakes. This study focuses on the Sei Dareh Cable-Stayed bridge that is at a relatively high level of vulnerability based on the 2017 Indonesia earthquake map. In this research, the study discussed the response of the Sei Dareh cable-stayed bridge under eleven ground motion accelerograms. The analysis was based on linear elastic conditions, so that it obtained the natural frequency, maximum displacement in the middle of the span and the top of the pylon, the stress of the cable and edge beam, and dynamic amplification factor (DAF). The three-dimensional finite element model (3D-FEM) of the bridge was established. Then, the model was analyzed under eleven ground motion accelerograms that have been scaled using the local design response spectra. The study reveals that the first and second mode of structure is a vertical translation with 0,71s and 0,49s periods respectively. TCU060 and Tabas accelerogram ground motions caused the largest cable forces and stress contrary to the Imperial ground motions. The analysis results under eleven ground motions show that the top pylon and deck mid-span satisfy the PTI code allowable displacements. The dynamic amplification factor (DAF) is under 2,0 as the limit value.
