Abstract
Kota Jakarta sebagai daerah dengan kepadatan penduduk yang tinggi, ketersediaan lahan yang terbatas, dan termasuk daerah yang rentan terhadap gempa memerlukan perencanaan gedung bertingkat dengan sistem penahan lateral yang memenuhi kriteria bangunan tahan gempa. Penggunaan sistem ganda (dual system), yaitu kombinasi antara dinding geser dan rangka pemikul momen yang dirancang untuk bekerja secara bersamaan dalam menahan beban. Dalam tugas akhir ini, dilakukan komparasi antara struktur eksisting dengan struktur baja beton komposit dengan dengan steel plate shear wall (SPSW). Pada gedung modifikasi digunakan pelat baja dengan ketebalan 3 sampai 6 mm. Konfigurasi dari SPSW diletakkan pada perimeter bangunan sebanyak 4 titik. Penggunaan steel plate shear wall (SPSW) pada gedung perkantoran 21 lantai di Jakarta memberikan perubahan signifikan terhadap perilaku struktur. Struktur modifikasi dengan SPSW memiliki berat mati 49,06 lebih rendah dan berat total 38,58% lebih rendah dibandingkan struktur eksisting. Struktur modifikasi mengalami peningkatan harga struktur atas sebesar 47,85% dan penurunan harga pondasi sebesar 52,64% sehingga total harga mengalami peningkatan sebesar 30,84%. Periode struktur modifikasi mengalami peningkatan sebesar 9,82% pada arah X dan 2,04% pada arah Y. Berdasarkan analisis respons spektra, penggunaan SPSW mampu mengurangi gaya geser dasar sebesar 47,68% pada arah X dan 46,52% pada arah Y. Respons simpangan antar tingkat mengalami peningkatan sebesar 15,05%% pada arah X dan 10,75% pada arah Y. Penggunaan SPSW meningkatkan efisiensi struktur dengan mengurangi berat bangunan dan gaya gempa secara signifikan. Meskipun terjadi peningkatan periode dan simpangan antar tingkat, nilai tersebut masih memenuhi persyaratan batas simpangan antar tingkat menurut SNI 1726:2019.

Jakarta, as a city with a high population density, limited land availability, and significant seismic vulnerability, requires the design of high-rise buildings with lateral force-resisting systems that satisfy earthquake-resistant building criteria. One commonly adopted approach is the dual system, which combines shear walls and moment-resisting frames designed to work together in resisting lateral loads. This undergraduate thesis compares the performance of an existing reinforced concrete structure with a modified steel–concrete composite structure incorporating a Steel Plate Shear Wall (SPSW) system. In the modified building, steel infill plates with thicknesses ranging from 3 to 6 mm were used. The SPSWs were installed at four locations along the building perimeter. The use of SPSWs in the 21-story office building in Jakarta resulted in significant changes in the structural behavior. The modified structure exhibited a 49.06% reduction in dead load and a 38.58% reduction in total structural weight compared with the existing structure. The cost of the superstructure increased by 47.85%, while the foundation cost decreased by 52.64%, resulting in an overall construction cost increase of 30.84%. The fundamental structural period increased by 9.82% in the X direction and 2.04% in the Y direction. Based on the response spectrum analysis, the implementation of SPSWs reduced the base shear by 47.68% in the X direction and 46.52% in the Y direction. The interstory drift increased by 15.05% in the X direction and 10.75% in the Y direction. Overall, the use of SPSWs improved structural efficiency by significantly reducing the building weight and seismic forces. Although the structural period and interstory drift increased, the drift values remained within the allowable limits specified by SNI 1726:2019.
