Abstract

Struktur jacket platform merupakan struktur lepas pantai yang menerima pembebanan berulang akibat gelombang serta pembebanan dinamis akibat gempa, sehingga diperlukan evaluasi untuk menjamin kemanan struktur. Penelitian ini bertujuan menganalisis pengaruh variasi bracing tipe K-brace, X-brace, dan Z-brace terhadap fatigue life dan kinerja struktur akibat beban gempa menggunakan perangkat lunak SACS. Analisis fatigue dilakukan dengan metode spectral, sedangkan analisis seismik menggunakan metode response spectrum pada kondisi SLE. Hasil analisis fatigue menunjukkan bahwa model K-brace dan X-brace memiliki fatigue life minimum masing-masing sebesar 15 tahun dan 16 tahun sehingga belum memenuhi umur rencana 20 tahun, sedangkan model Z-brace memiliki fatigue life minimum sebesar 20 tahun sehingga masih memenuhi kriteria desain. Analisis seismik menunjukkan nilai unity check maksimum untuk K-brace, X-brace, dan Z-brace masih berada di bawah batas izin sebesar 1.0 sehingga ketiga model memenuhi persyaratan desain. Berdasarkan hasil penelitian, konfigurasi Z-brace memberikan kinerja fatigue terbaik, sedangkan K-brace menunjukkan kinerja seismik terbaik dengan nilai unity check terendah.
