<![CDATA[The Indonesian National Standard (SNI 1726:2019), which serves as the basis for seismic design, does not explicitly distinguish between cantilever and coupled shear wall systems, despite their different seismic behavior characteristics. This study aims to evaluate the performance of reinforced concrete coupled shear wall structures in a dual system for 8, 12, and 16-story buildings using response spectrum analysis and nonlinear pushover analysis. The results indicate that the base shear capacity increases with the number of stories, ranging from approximately 28.000 kN to 35.000 kN, while the target displacement ranged from 0,667% to 0,862% of the total building height. All building models achieved the Immediate Occupancy (IO) performance level, with a maximum difference of 8.43% between the displacement coefficient method and the capacity spectrum method. The initial yielding mechanism occurred in the coupling beams as intended in the design, and at the final stage of the pushover analysis, the coupling beams exceeded the Collapse Prevention (CP) limit. Meanwhile, the main beams remained within the IO level, and the shear walls and columns stayed elastic. The structural response modification factor (R) increased from 3 to 4 as the number of stories increased, indicating an improvement in the structure's energy dissipation capacity. The findings demonstrate that coupled shear wall systems in a dual structural system provide good seismic performance and exhibit ductile structural behavior. Abstrak Standar Nasional Indonesia 1726:2019 yang digunakan sebagai acuan perencanaan ketahanan gempa di Indonesia belum secara eksplisit membedakan sistem struktur dinding geser kantilever dan dinding geser berangkai, walaupun kedua sistem memiliki karakteristik perilaku seismik yang berbeda. Penelitian ini bertujuan mengevaluasi kinerja struktur dinding geser berangkai beton bertulang dalam sistem ganda pada bangunan 8, 12, dan 16 lantai menggunakan analisis respons spektrum dan pushover nonlinier. Hasil penelitian menunjukkan kapasitas base shear struktur meningkat seiring bertambahnya jumlah lantai, dengan rentang sekitar 28.000-35.000 kN, sedangkan target perpindahan berkisar antara 0,667-0,862% terhadap total tinggi bangunan. Seluruh model bangunan berada pada level kinerja Immediate Occupancy (IO) dengan perbedaan hasil metode koefisien perpindahan dan kapasitas spektrum maksimum sebesar 8,43%. Mekanisme pelelehan awal terjadi pada balok perangkai sesuai perencanaan, dan pada tahap akhir pushover balok perangkai telah melewati batas Collapse Prevention (CP), sedangkan balok induk masih berada pada level IO serta dinding geser dan kolom tetap elastik. Nilai faktor modifikasi respons struktur (R) meningkat dari 3 hingga 4 seiring bertambahnya jumlah lantai, yang menunjukkan peningkatan kemampuan struktur dalam mendisipasikan energi gempa. Hasil penelitian menunjukkan sistem dinding geser berangkai dalam sistem ganda memiliki kinerja seismik yang baik dan perilaku struktur yang daktail.]]>
