Abstract

This study aims to evaluate the performance of steel pile foundations for the abutment of the Sei Ella 1 Bridge, located at the Ela River, West Kalimantan, with soil conditions consisting of sedimentary layers. The analysis was conducted based on actual piling conditions, where pile depths vary between 4.015 meters and 5.823 meters. The evaluation includes calculating the single pile bearing capacity using the Decourt method, analyzing group pile capacity with the efficiency group approach, and assessing lateral deformation and settlement using the Finite Element Method (FEM). The results show that the single pile and group pile capacities are sufficient to withstand the loads from the superstructure, abutment self-weight, and lateral soil pressure. The lateral deformation analysis yielded a deflection value of 2.83 mm, while the settlement was recorded at 0.1152 mm. Both values are well below the maximum limit set by SNI 8460:2017, which is 12.5 mm, indicating that the foundation is in a safe and stable condition. This study provides a deeper understanding of the performance of steel pile foundations for the abutment of the Sei Ella 1 Bridge. As an additional verification step, it is recommended to conduct Static Loading Tests (compressive, tensile, and lateral) to validate the analysis results. This approach offers a robust foundation for ensuring the safety, stability, and feasibility of the design under actual conditions..

Abstract

Penelitian ini bertujuan untuk mengeksplorasi penggunaan Bridge Management System (BMS) yang digabungkan dengan pengujian Non-Destructive Testing (NDT) berupa Ultrasonic Pulse Velocity (UPV) dan Schmidt Hammer Test untuk menilai kondisi jembatan pada ruas jalan Batas Kabupaten Lamongan – Batas Kota Gresik. Analisis dilakukan dengan tujuan untuk mengembangkan model prediksi umur jembatan yang lebih akurat dengan mengintegrasikan hasil survei visual dan data teknis dari uji NDT. Hasil penelitian menunjukkan bahwa nilai kondisi jembatan (NK) memiliki hubungan yang signifikan dengan mutu beton yang diukur menggunakan metode NDT, di mana semakin tinggi nilai NK, semakin rendah kualitas beton dan kecepatan rambat gelombang ultrasonik. Berdasarkan model prediksi, jembatan dengan nilai kondisi lebih baik diprediksi memiliki umur sisa yang lebih panjang, sementara jembatan dengan nilai kondisi lebih buruk memerlukan tindakan pemeliharaan lebih mendesak. Penelitian ini memberikan kontribusi terhadap pengembangan sistem manajemen jembatan yang lebih efisien, meningkatkan keselamatan infrastruktur, serta memberikan rekomendasi pemeliharaan berbasis data untuk jembatan-jembatan yang terletak di koridor strategis Provinsi Jawa Timur.

Abstract

ABSTRAKDermaga Petikemas Tarakan yang telah beroperasi sekitar 20 tahun direncanakan menerima tambahan beban Harbour Mobile Crane (HMC). Penelitian ini mengevaluasi kinerja statik dan fatik struktur eksisting menggunakan data survei visual, Non-Destructive Test, core drill, pemodelan SAP2000, kurva Wöhler/S-N, dan aturan Palmgren-Miner. Kuat tekan minimum core drill 24,63 MPa digunakan sebagai parameter konservatif. Hasil statik menunjukkan balok dan pelat 450 mm memenuhi, sedangkan pelat 350 mm tidak memenuhi. Analisis fatik menunjukkan beton pelat 350 mm gagal dengan D = 5.443.281,091, sementara beton pelat 450 mm dan balok masih memenuhi dengan D masing-masing 0,6047 dan 3,177 × 10⁻⁸. Operasional HMC perlu dibatasi pada area yang memenuhi atau disertai redistribusi beban dan perkuatan lokal.Katakunci: analisis fatik, analisis statik, dermaga petikemas, Harbour Mobile Crane, Palmgren-Miner ABSTRACTThe 20-year-old Tarakan Container Wharf is planned to accommodate additional Harbour Mobile Crane (HMC) loading. This study evaluates the static and fatigue performance of the existing wharf by integrating visual inspection, Non-Destructive Testing, core drilling, SAP2000 modelling, Wöhler/S-N curves, and Palmgren-Miner damage accumulation. The minimum core compressive strength of 24.63 MPa was adopted as a conservative material parameter. Static evaluation indicates that the beams and 450 mm slab remain adequate, whereas the 350 mm slab is inadequate. Fatigue analysis shows that the concrete of the 350 mm slab fails with D = 5,443,281.091, while the 450 mm slab and beam satisfy the fatigue limit with D values of 0.6047 and 3.177 × 10⁻⁸, respectively. HMC operation should therefore be limited to acceptable areas or supported by load redistribution and local strengthening.Keyword: fatigue analysis, static analysis, container wharf, Harbour Mobile Crane, Palmgren-Miner
