Abstract
Penambahan jumlah lantai pada bangunan bertingkat memerlukan evaluasi menyeluruh terhadap kinerja struktur, khususnya dalam menahan beban lateral akibat gempa. Studi ini bertujuan untuk merencanakan ulang struktur atas Gedung X di Tangerang yang mengalami perubahan dari 8 menjadi 11 lantai, dengan menerapkan sistem struktur ganda tahan gempa yang terdiri atas Sistem Rangka Pemikul Momen Khusus (SRPMK) dan Sistem Dinding Struktural Khusus (SDSK). Analisis struktur dilakukan menggunakan metode respons spektrum sesuai SNI 1726:2019, dan perancangan elemen struktur mengacu pada SNI 2847:2019. Berdasarkan hasil analisa pemodelan awal dengan perbesaran dimensi kolom dan balok, struktur atas Gedung X 11 lantai di Tangerang masih belum memenuhi syarat simpangan antar lantai (drift) dan rasio strong column–weak beam (SCWB). Oleh karena itu, dilakukan perencanaan ulang elemen struktur atas menggunakan sistem struktur ganda. Hasil akhir menunjukkan peningkatan base shear sebesar 34,81%, penurunan periode struktur sebesar 42,61%, rotasi berkurang 17,79%, dan simpangan antar tingkat menurun 9,37%, yang menunjukkan peningkatan kekakuan dan kontrol deformasi yang lebih baik. Sistem juga memenuhi distribusi gaya dasar minimum 25% sesuai SNI 1726:2019 yaitu 29,92% pada arah x dan 25,12% parah arah y. ***** The addition of floors in a multi-story building requires a comprehensive evaluation of the structural performance, particularly in resisting lateral loads due to earthquakes. This study aims to redesign the superstructure of Building X in Tangerang, which underwent a modification from 8 to 11 floors, by implementing a dual seismic-resisting system consisting of a Special Moment Resisting Frame (SMRF) and Special Structural Walls (SSW). Structural analysis was carried out using the response spectrum method in accordance with SNI 1726:2019, and the design of structural elements refers to SNI 2847:2019. Based on the initial modeling results using enlarged column and beam dimensions, the 11-story superstructure of Building X in Tangerang still did not satisfy the inter-story drift and strong column weak beam (SCWB) ratio requirements. Therefore, a redesign of the superstructure elements was conducted using a dual structural system. The final results show an increase in base shear by 34.81%, a reduction in structural period by 42.61%, a decrease in rotation by 17.79%, and a reduction in inter-story drift by 9.37%, indicating improved stiffness and better deformation control. The system also meets the minimum 25% base shear distribution requirement as specified in SNI 1726:2019, with values of 29,92% in x direction and 25,12% in y direction.
