Abstract
A suspension bridge is a long span bridge that has the advantage of the possibility of not having a pillar in the middle and using cables as the primary load bearer. Due to its long spans, the analysis of the bridge should be treated very carefully, especially under an earthquake. The earthquake that occurs will cause ground movement to affect the performance of the bridge structure. Furthermore, various soil conditions will also cause the existence of the bridge structure to experience differences. In this study, a super long-span suspension bridge is analyzed under different soil conditions. It is assumed that each support of the bridge is on the same ground condition and has a uniform ground movement. The bridge is then analyzed relating to the response of the bridge structure due to a uniform earthquake in the form of internal forces and displacement both in terms of static and dynamic analysis. Results show that soft soil induces a more massive internal forces response structure compared to hard soil.
