Abstract
Kolom merupakan elemen vertikal dalam suatu struktur bangunan yang berfungsi menahan beban aksial dan momen akibat beban gravitasi maupun beban lateral. Oleh karena itu, kolom memiliki peran krusial dalam menjaga keutuhan struktur. Kinerja struktur menjadi aspek penting dalam menilai performa struktur terhadap gempa berdasarkan tingkat kerusakan yang ditimbulkan oleh gempa dengan periode ulang tertentu. Penelitian ini bertujuan untuk membandingkan tingkat kinerja struktur dari nilai simpangan berdasarkan variasi bentuk penampang kolom, pemodelan pada penelitian ini dibantu program ETABS 18. Analisis dilakukan terhadap tiga model struktur yaitu, model dengan kolom penampang persegi panjang, penampang bulat, dan penampang persegi. dengan analisis beban gempa menggunakan respons spektrum. Penentuan level kinerja struktur dilakukan berdasarkan kriteria ATC-40. Hasil analisis menunjukkan bahwa struktur kolom persegi Panjang memiliki nilai perpindahan maksimum 97,575 mm untuk arah X dan 63,005 mm untuk arah Y, kolom bulat dengan arah X sebesar 91.782 mm dan arah Y sebesar 62,966 mm kolom persegi dengan arah X sebesar 91.946 mm dan arah Y sebesar 63,052 dan untuk nilai simpangan maksmum kolom persegi panjang sebesar 48,444 untuk arah X dan 26,818 untuk arah Y, kolom bulat sebesar 45,590 untuk arah X dan 26,763 untuk arah Y, kolom persegi 45,540 untuk arah X dan 26,813 untuk arah Y. Meskipun terdapat perbedaan nilai simpangan antar model, ketiga model struktur menunjukkan level kinerja yang sama berdasarkan ATC-40, yaitu Immediate Occupancy (IO). Hal ini menunjukkan bahwa setelah terjadi gempa, kerusakan yang terjadi tergolong ringan dan struktur masih mempertahankan kekuatan serta kekakuannya hampir setara dengan kondisi semula. A column is a vertical element in a building structure that functions to resist axial loads and moments resulting from both gravity and lateral loads. Therefore, columns play a crucial role in maintaining the integrity of the structure. Structural performance is an essential aspect in evaluating a structure's behavior during an earthquake, based on the level of damage caused by an earthquake with a specific return period. This study aims to compare the structural performance levels based on displacement values resulting from variations in column cross-sectional shapes. The modeling in this study was carried out using ETABS 18 software. The analysis was conducted on three structural models with different column cross-sections: rectangular, circular, and square. Seismic load analysis was performed using the response spectrum method. The structural performance level was determined based on the ATC-40 criteria. The analysis results show that the structure with rectangular columns experienced maximum displacements of 97.575 mm in the X direction and 63.005 mm in the Y direction. The circular column model had maximum displacements of 91.782 mm in the X direction and 62.966 mm in the Y direction, while the square column model had displacements of 91.946 mm in the X direction and 63.052 mm in the Y direction. For maximum drift values, the rectangular column model exhibited 48.444 mm in the X direction and 26.818 mm in the Y direction; the circular column model showed 45.590 mm in the X direction and 26.763 mm in the Y direction; and the square column model recorded 45.540 mm in the X direction and 26.813 mm in the Y direction. Although there are differences in displacement values among the models, all three structural models demonstrated the same performance level based on ATC-40, which is Immediate Occupancy (IO). This indicates that after an earthquake event, the resulting damage is categorized as minor, and the structure is still capable of maintaining its strength and stiffness, nearly equivalent to its original condition.
