Abstract
Indonesia merupakan wilayah dengan potensi gempa yang tinggi akibat posisinya pada pertemuan tiga lempeng tektonik utama. Kondisi ini menuntut agar bangunan bertingkat mampu bertahan, tidak mengalami keruntuhan, dan tetap dapat beroperasi pascagempa. Gedung Perkantoran Cimory Head Office yang semula direncanakan sebagai struktur beton bertulang 14 lantai setinggi 66,5 meter dengan Sistem Rangka Pemikul Momen Khusus (SRPMK) menjadi objek studi dalam tugas akhir ini. Struktur dimodifikasi menjadi gedung baja 20 lantai setinggi 92 meter dengan penerapan sistem Steel Plate Shear Wall (SPSW) sebagai penahan gaya lateral utama yang bekerja bersama rangka pemikul momen dalam konfigurasi sistem ganda (dual system). SPSW dipilih karena kemampuannya memberikan kekakuan dan daktilitas yang tinggi serta bobot struktur yang lebih ringan dibandingkan dinding geser beton konvensional. Seluruh elemen baja direncanakan menggunakan material ASTM A36 (Fy = 250 MPa) dengan pelat pengisi SPSW setebal 15 mm. Analisis struktur dilakukan secara tiga dimensi menggunakan program bantu ETABS dengan metode respons spektrum yang mengacu pada SNI 1726:2019, SNI 1727:2020, dan SNI 1729:2020. Hasil analisis menunjukkan struktur modifikasi memiliki periode sebesar 2,117 detik pada arah X dan 2,034 detik pada arah Y, dengan partisipasi massa telah melampaui 90% pada kedua arah. Berdasarkan distribusi sistem ganda, SPSW memikul 27,31% gaya geser pada arah X dan 29,47% pada arah Y, sedangkan rangka pemikul momen memikul sisanya, sehingga persyaratan sistem ganda terpenuhi. Simpangan antar tingkat maksimum sebesar ±34,8 mm masih berada di bawah batas izin 69,231 mm, dan pengaruh P-Delta dapat diabaikan karena koefisien stabilitas jauh di bawah 0,1. Dengan demikian, penerapan SPSW terbukti efektif dalam mengontrol simpangan antar tingkat (drift) dan menghasilkan struktur baja tahan gempa yang memenuhi persyaratan kekuatan (strength) dan kenyamanan (serviceability). Hasil akhir perencanaan dituangkan dalam bentuk gambar teknik dan laporan analisis perhitungan.

Indonesia is a region of high seismicity due to its location at the convergence of three major tectonic plates, requiring high-rise buildings to withstand earthquakes without collapse and to remain operational afterward. The Cimory Head Office Building, originally designed as a 14-story reinforced concrete structure 66.5 meters high using a Special Moment Resisting Frame (SMRF) system, is the subject of this final project. The structure is modified into a 20-story steel building 92 meters high with a Steel Plate Shear Wall (SPSW) system as the primary lateral force-resisting element, working together with moment-resisting frames in a dual system configuration. SPSW was selected for its high stiffness and ductility as well as its lighter weight compared to conventional concrete shear walls. All steel elements are designed using ASTM A36 material (Fy = 250 MPa) with a 15 mm thick SPSW infill plate. A three-dimensional structural analysis was carried out using ETABS software with the response spectrum method in accordance with SNI 1726:2019, SNI 1727:2020, and SNI 1729:2020. The results show that the modified structure has a fundamental period of 2.117 seconds in the X direction and 2.034 seconds in the Y direction, with mass participation exceeding 90% in both directions. Based on the dual system distribution, the SPSW resists 27.31% of the base shear in the X direction and 29.47% in the Y direction, while the moment-resisting frame resists the remainder, satisfying the dual system requirement. The maximum inter-story drift of ±34.8 mm remains below the permissible limit of 69.231 mm, and P-Delta effects are negligible because the stability coefficient is far below 0.1. Thus, the application of SPSW is proven effective in controlling inter-story drift and producing an earthquake-resistant steel structure that satisfies strength and serviceability requirements. The final design outcomes are presented in the form of engineering drawings and a calculation analysis report.
