Abstract

Pertumbuhan penduduk Kota Bekasi yang pesat meningkatkan kebutuhan hunian vertikal sehingga pembangunan apartemen bertingkat menjadi solusi atas keterbatasan lahan. Kota Bekasi berada di wilayah rawan gempa yang sehingga struktur bangunan tinggi harus dirancang dengan ketahanan gempa yang memadai. Dalam pelaksanaannya, Gedung Apartemen Tower Isabella Grand Kemala Lagoon dibangun menggunakan Sistem Rangka Pemikul Momen Khusus (SRPMK) yang dikombinasikan dengan dinding geser beton bertulang (shear wall). Pada tugas akhir ini, dilakukan studi komparasi antara struktur eksisting tersebut dengan alternatif struktur baja-beton komposit dengan Steel Plate Shear Wall (SPSW). SPSW ditempatkan pada sudut-sudut bangunan karena posisi tersebut memiliki eksentrisitas terbesar terhadap pusat massa sehingga lebih efektif dalam menahan torsi dan mengakomodasi displacement antar lantai akibat gaya gempa. Pada gedung modifikasi digunakan SPSW tipe unstiffened dengan tebal pelat 7 mm, 6 mm, 5 mm, 4 mm, dan 3 mm. Berdasarkan hasil analisis yang telah dilakukan, struktur modifikasi dengan sistem Unstiffened Steel Plate Shear Wall (SPSW) menunjukkan perbedaan yang signifikan apabila dibandingkan dengan struktur eksisting. Dari segi berat struktur, diperoleh bahwa berat material struktur dan berat seismik struktur modifikasi lebih ringan sebesar 35% dan 24% dari struktur eksisting. Periode fundamental struktur modifikasi meningkat 6% (arah-X) dan 11% (arah-Y) dari struktur eksisting, serta gaya geser dasar struktur modifikasi menurun 33% pada kedua arah dari struktur eksisting. Simpangan antar lantai rata-rata struktur modifikasi meningkat sebesar 50% (arah-X) dan 22% (arah-Y) akibat penurunan kekakuan efektif struktur. Berdasarkan hasil perbandingan simpangan antar lantai tersebut, menunjukkan bahwa struktur modifikasi memiliki daktilitas yang lebih tinggi daripada struktur eksisting. Adapun untuk perbandingan jumlah kebutuhan pondasi pada struktur modifikasi 14% lebih sedikit dibandingkan struktur eksisting.

The rapid population growth of Bekasi City has increased the demand for vertical housing, making the construction of high-rise apartments a solution to limited land availability, and since Bekasi City is located in a seismically active region, high-rise structures must be designed with adequate earthquake resistance. In practice, the Isabella Grand Kemala Lagoon Apartment Tower was constructed using a Special Moment Resisting Frame (SMRF) combined with reinforced concrete shear walls, and this final project conducts a comparative study between the existing structure and an alternative composite steel-concrete structure incorporating a Steel Plate Shear Wall (SPSW), which is positioned at the corners of the building due to its greatest eccentricity from the center of mass, making it more effective in resisting torsion and accommodating interstory displacement caused by seismic loads, with the modified building employing an unstiffened SPSW of varying plate thicknesses of 7 mm, 6 mm, 5 mm, 4 mm, and 3 mm. Based on the analysis results, the modified structure shows significant differences compared to the existing structure: the material weight and seismic weight are lighter by 35% and 24%, respectively; the fundamental period increases by 6% in the X-direction and 11% in the Y-direction; the base shear force decreases by 33% in both directions; and the average interstory drift increases by 50% in the X-direction and 22% in the Y-direction due to the reduction in the structure's effective stiffness, indicating that the modified structure exhibits higher ductility than the existing structure, while the number of foundation piles required is 14% fewer than that of the existing structure.
