Abstract
This study was conducted to analyze the impact of adding five additional floors to the existing structure of Rusun Semesta Mahata Serpong Tower B2, as well as to evaluate the effectiveness of the Concrete Jacketing method as a structural strengthening solution. The analysis was carried out using ETABS software through three structural models: the initial structure (Model 1), the structure after the addition of floors (Model 2), and the structure after strengthening (Model 3). The analysis results show that the addition of floors causes an increase in both vertical and lateral loads, along with higher displacement and inter-story drift. In Model 2, the displacement in the X-direction reached 159.85 mm and in the Y-direction reached 185.23 mm. The inter-story drift in the Y-direction on the 25th floor reached 62.568 mm, exceeding the allowable limit according to SNI 1726:2019 (60 mm), indicating that the structure is no longer safe. After applying the Concrete Jacketing method, displacement was reduced to 126.36 mm (X) and 150.77 mm (Y), and the inter-story drift in the Y-direction was reduced to 47.751 mm. The axial capacity of the columns increased from 59,089 kN to 98,054 kN. Keywords: Floor addition, existing structure, concrete jacketing, inter-story drift, structural strengthening Penelitian ini dilakukan untuk menganalisis pengaruh penambahan 5 lantai baru pada struktur bangunan eksisting Rusun Semesta Mahata Serpong Tower B2, serta mengevaluasi efektivitas metode Concrete Jacketing sebagai solusi perkuatan struktur. Analisis dilakukan menggunakan program ETABS dengan tiga model: struktur awal (Model 1), struktur setelah penambahan lantai (Model 2), dan struktur yang telah diperkuat (Model 3). Hasil analisis menunjukkan bahwa penambahan lantai menyebabkan peningkatan gaya vertikal dan lateral, serta kenaikan displacement dan simpangan antar lantai. Pada Model 2, displacement arah X mencapai 159,85 mm dan arah Y sebesar 185,23 mm. Simpangan antar lantai arah Y di lantai 25 mencapai 62,568 mm, melebihi batas izin SNI 1726:2019 (60 mm), sehingga struktur dianggap tidak aman. Setelah diterapkan perkuatan dengan Concrete Jacketing, displacement menurun menjadi 126,36 mm (X) dan 150,77 mm (Y), serta simpangan arah Y menjadi 47,751 mm. Kapasitas tekan kolom meningkat dari 59.089 kN menjadi 98.054 kN. Kata Kunci : Penambahan lantai, struktur eksisting, concrete jacketing, simpangan antar lantai, Perkuatan struktur
