Abstract
Bangunan bertingkat menjadi solusi dalam mengoptimalkan lahan dan menjaga ruang terbuka hijau (RTH). Dalam perencanaannya, ketahanan gempa menjadi aspek penting demi keselamatan penghuni. Sistem portal kaku kerap digunakan untuk meredam gaya lateral, namun pada bangunan tinggi dibutuhkan elemen tambahan seperti shear wall. Salah satu inovasi penahan beban lateral adalah Unstiffened Steel Plate Shear Wall (USPSW) yang unggul dalam kekuatan pasca tekuk dan daktilitas, namun lemah terhadap deformasi tekuk luar. Integrasi USPSW dengan Concrete Filled Steel Tube (CFST) menjadi solusi untuk meningkatkan kekakuan dan ketahanan deformasi.Penelitian ini meliputi studi literatur, pengumpulan data, analisis beban, pemodelan dan analisis struktur eksisting serta modifikasi, perencanaan elemen struktur, sambungan, dan fondasi, pembuatan gambar kerja, serta perhitungan dan perbandingan Rencana Anggaran Biaya (RAB). Standar yang digunakan antara lain SNI 1729:2020, SNI 1726:2019, SNI 1727:2020, AISC Steel Guide, dan lainnya. Hasil menunjukkan Struktur eksisting mencapai partisipasi massa 99% pada mode ke-250, sedangkan struktur modifikasi pada mode ke-50. Periode fundamental meningkat dari 1,76 detik menjadi 2,14 detik. Gaya geser dasar pada kedua struktur menunjukkan gaya dinamik lebih besar dari gaya statik. Simpangan antar lantai struktur modifikasi sebesar 20,5 mm (X) dan 19,3 mm (Y), sedangkan struktur eksisting sebesar 18,7 mm (X) dan 24,8 mm (Y), masih dalam batas izin. Partisipasi shear wall meningkat dari 51% dan 42% menjadi 70% dan 88%. Kontrol sistem ganda, P-Delta, dan ketidakberaturan struktur pada kedua struktur telah memenuhi syarat. Rencana Anggaran Biaya (RAB) struktur modifikasi sebesar Rp96.241.390.837,83 lebih tinggi dibandingkan struktur eksisting sebesar Rp37.010.729.000,28, dengan selisih biaya sebesar Rp59.230.661.837,55.

High-rise buildings are a solution to optimize land use while preserving green open spaces (RTH). In their design, earthquake resistance is a critical aspect to ensure occupant safety. Rigid frame systems are commonly used to resist lateral forces; however, taller buildings require additional elements such as shear walls. One innovative lateral force-resisting system is the Unstiffened Steel Plate Shear Wall (USPSW), which offers advantages in post-buckling strength and ductility, yet lacks resistance to out-of-plane deformation. ntegrating USPSW with Concrete Filled Steel Tube (CFST) columns serves as a solution to improve lateral stiffness and deformation resistance. This study includes literature review, data collection, load analysis, modeling and analysis of the existing and modified structures, structural element and connection design, foundation planning, working drawings, and cost estimation comparison. The standards used include SNI 1729:2020, SNI 1726:2019, SNI 1727:2020, the AISC Steel Design Guide, and others. the results show that the existing structure reaches 99% mass participation at mode 250, while the modified structure achieves it at mode 50. The fundamental period increases from 1.76 seconds to 2.14 seconds. In both structures, dynamic base shear exceeds static base shear. Inter-story drifts remain within permissible limits: 20.5 mm (X) and 19.3 mm (Y) for the modified structure, compared to 18.7 mm (X) and 24.8 mm (Y) for the existing structure. Shear wall participation increased from 51% and 42% to 70% and 88% in the X and Y directions, respectively. Both structures meet the dual system, P-Delta, and structural irregularity requirements. The cost estimation for the modified structure is IDR 96,241,390,837.83, significantly higher than the existing structure's IDR 37,010,729,000.28, with a difference of IDR 59,230,661,837.55.
