Abstract

This study analyzes the performance level of a typical pier structure on the Jakarta-Bandung High-Speed Railway (HSR) bridge located in the Bandung area, focusing on the effects of seismic loads. The structure utilizes double spherical bearings (isolators), and its performance is compared with a similar structure without isolators to evaluate the isolators’ effectiveness under design-level earthquakes. A Non-linear Time History Analysis (NLTHA) was conducted using 11 pairs of ground motion records. These motions were scaled to match the target response spectrum for Bandung using amplitude scaling in the DeepSoil program. Structural analysis was carried out using Midas Civil to determine the seismic performance levels of the piers Additionally, pier displacements were examined to further assess isolator performance. The results show that the structure equipped with isolators maintained a Fully Operational (FO) performance level, indicating minimal damage and full functionality after the earthquake. In contrast, the structure without isolators surpassed the elastic range but remained within the Immediate Occupancy (IO) performance level, suggesting minor damage but continued usability. These findings confirm that the use of isolators significantly enhances the seismic resilience of bridge piers in high-speed railway.

Abstract

Beton adalah material konstruksi yang diperoleh dari pencampuran pasir, kerikil/agregat kasar, semen serta air. Di sisi lain penggunaan kerikil yang merupakan sumber daya alam yang tidak dapat diperbaharui secara terus menerus sebagai bahan beton dikhawatirkan merusak lingkungan. Dalam mengatasi isu itu maka riset tentang konstruksi hijau (Green Construction) mulai digalakkan dengan salah satunya adalah pemanfaatan limbah batu kerajinan di Padalarang. Tujuan penelitian adalah mengetahui komposisi optimum agregat kasar dari limbah pada beton sehingga menghasilkan kuat tekan yang maksimum. Tahapan Pertama dalam penelitian ini adalah pengumpulan data selanjutnya adalah analisis Laboratorium meliputi uji sifat teknis material penyusun beton yang meliputi pasir , kerikil alami dan kerikil dari limbah batu kerajinan. Selanjutnya proses mix desain dimana penelitian dilakukan dengan 30 benda uji dengan komposisi antara split dan limbah adalah 100% : 0%, 80% : 20%, 60% : 40%, 40% : 60%, 20% : 80% dan 0 % :100 %, masing masing komposisi berjumlah lima benda uji. Pengujian meliputi berat jenis, kuat tekan dan modulus elastisitas beton. Hasil penelitian menunjukkan kuat tekan maksimum diperoleh pada proporsi 40% split dan 60% limbah yaitu 14.35 MPa. Modulus elastisitas maksimum diperoleh pada proporsi 20% split dan 80% limbah yaitu 18367.8 MPa.
