Abstract

English

The large deck openings of ultra-large container ships greatly reduce their torsional stiffness, and hydroelastic analysis is a must for reliable structural design. In the initial design stage, the beam model is a rational choice. This study aims to investigate torsion's effect on container ships' strength using a numerical approach based on fatigue boundary conditions and ultimate boundary conditions in the midship region. Regarding fatigue boundary conditions, the dimensional influence of the container ship is obtained at the connection between the longitudinal side shell stiffeners and the transverse web frame for nine structural details, which refer to different arrangements of reinforcing elements. The structural influence on the local stress distribution was assessed along the longitudinal plates between the regular stiffeners bounding the perimeter of the torsion box by calculating the hull girder stresses. Keywords: Container Ships, Cross Section, Torsion, Longitudinal Strength

Bahasa Indonesia

Bukaan dek yang besar pada kapal kontainer ultra-besar sangat mengurangi kekakuan puntirnya, dan analisis hidroelastis adalah suatu kebutuhan untuk kebutuhan desain struktur yang andal. Pada tahap desain awal, model balok adalah pilihan yang rasional. Penelitian ini bertujuan untuk menginvestigasi pengaruh torsi terhadap kekuatan kapal kontainer dengan menggunakan pendekatan numerik berdasarkan kondisi batas fatik dan kondisi batas ultimit di daerah midship. Pada kondisi kelelahan batas, pengaruh dimensi kapal peti kemas diperoleh pada sambungan antara pengaku cangkang sisi memanjang dan rangka web melintang hingga sembilan detail struktur, yang mengacu pada pengaturan elemen penguat yang berbeda. Pengaruh struktural pada distribusi tegangan lokal dikaji di sepanjang pelat memanjang antara pengaku reguler yang membatasi perimeter kotak torsi dengan menghitung tegangan gelagar lambung. Kata kunci: Kapal Peti Kemas, Penampang Melintang, Torsi, Kekuatan Memanjang
