Abstract

Penelitian ini berfokus pada analisis kekuatan tekuk pada panel sekat berlubang yang mengalami beban tekan aksial dengan menggunakan Metode Elemen Hingga. Sekat berlubang sering digunakan dalam struktur kapal untuk memungkinkan aliran fluida serta mengurangi berat struktur. Namun, keberadaan lubang dapat memengaruhi integritas struktur terhadap beban aksial. Dalam studi ini, empat variasi model sekat berlubang dianalisis dengan perbedaan jumlah dan tata letak lubang berbentuk lingkaran. Hasil analisis berupa nilai beban kritis dan pola deformasi diperoleh melalui simulasi buckling berbasis eigenvalue. Seluruh model menunjukkan terjadinya buckling, dengan nilai beban kritis terendah ditemukan pada mode buckling pertama. Di antara keempat variasi, model keempat yang menerapkan strategi penempatan lubang secara selektif menunjukkan nilai beban kritis tertinggi dan stabilitas struktur yang baik. Sebagian besar pola deformasi yang diamati berupa buckling lokal, terutama pada bagian pelat di antara penegar. Penelitian ini menegaskan pentingnya konfigurasi lubang dalam menjaga efisiensi sekaligus kestabilan struktur.

This research focused on the buckling strength analysis of perforated bulkhead panels subjected to axial compressive loads using the Finite Element Method (FEM). Perforated bulkheads were commonly used in ship structures to allow fluid passage while reducing structural weight. However, the presence of holes influenced the structural integrity under axial loads. In this study, four variations of perforated bulkhead models were analyzed, each differing in the number and arrangement of circular holes. The critical buckling loads and deformation modes were obtained from eigenvalue buckling simulations. The results indicated that all models experienced buckling, with the lowest critical load observed in the first buckling mode. Among the four models, the fourth variation, which utilized a more selective hole placement strategy, demonstrated the highest critical load and better overall structural stability. Most deformation patterns observed were local buckling, particularly in the plate sections between stiffeners. This study emphasized the importance of hole configuration in maintaining the balance between structural efficiency and stability.
