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 mutu tinggi banyak digunakan dalam konstruksi modern karena memiliki kekuatan tekan yang tinggi. Namun, material ini memiliki kelemahan berupa sifat getas yang menyebabkan kemampuan menahan beban lentur dan mengontrol retak menjadi terbatas. Berbagai penelitian telah menunjukkan bahwa penambahan serat dapat meningkatkan daktilitas dan ketahanan retak beton. Meskipun demikian, kajian mengenai pengaruh serat polipropilena terhadap kapasitas momen balok beton mutu tinggi, khususnya pada kombinasi dengan tulangan lentur konvensional, masih terbatas. Oleh karena itu, penelitian ini bertujuan untuk mengevaluasi pengaruh penambahan serat polipropilena terhadap kapasitas momen dan perilaku retak balok beton mutu tinggi. Penelitian dilakukan secara eksperimental dengan membuat empat tipe spesimen balok beton mutu tinggi, yaitu: (1) balok tanpa serat polipropilena sebagai spesimen kontrol, (2) balok dengan penambahan serat polipropilena sebesar 0,5%, (3) balok dengan tulangan lentur D13, dan (4) balok dengan tulangan lentur D13 serta serat polipropilena sebesar 0,5%. Seluruh spesimen diuji menggunakan metode pembebanan lentur hingga mencapai kondisi kegagalan. Parameter yang diamati meliputi beban maksimum, deformasi balok dan kapasitas momen. Hasil pengujian menunjukkan bahwa penambahan serat polipropilena mampu meningkatkan kapasitas momen balok dibandingkan dengan balok tanpa serat. Kombinasi antara tulangan lentur D13 dan serat polipropilena juga menunjukkan kinerja struktural yang lebih baik dibandingkan spesimen lainnya. Penambahan serat polipropilena terbukti mampu meningkatkan kapasitas momen serta meningkatkan daktilitas balok beton mutu tinggi. Temuan ini menunjukkan bahwa penggunaan serat polipropilena berpotensi menjadi solusi efektif untuk meningkatkan kinerja lentur beton mutu tinggi pada elemen struktur balok.
