Abstract

Pembangunan supertall building di kawasan urban seperti Jakarta merupakan solusi atas keterbatasan lahan dan meningkatnya kebutuhan ruang vertikal. Namun, tingginya bangunan menyebabkan tantangan besar dalam menahan gaya lateral akibat gempa, sehingga dibutuhkan sistem struktur yang efisien dan tangguh. Penelitian ini bertujuan untuk mengevaluasi efektivitas sistem belt truss dan outrigger dalam mereduksi perpindahan (displacement) dan simpangan antar tingkat (drift), serta mengevaluasi kinerja struktur berdasarkan ATC-40, dengan studi kasus Thamrin Nine Autograph Tower. Struktur supertall building dievaluasi dengan pembebanan gempa menggunakan metode response spectrum, kemudian dilakukan analisis numerik menggunakan pemodelan 3D pada software ETABS 2020. Penelitian mencakup tiga pemodelan: model 1 (sistem eksisting di lantai 35–36 dan 55–57), model 2 (tanpa sistem), dan model 3 (sistem pada lantai 18–20, 37–39, dan 56–57). Hasil analisis menunjukkan bahwa model 1 menunjukkan displacement 329.195 mm (X) dan 342.202 mm (Y), serta drift 31.224 mm (X) dan 33.076 mm (Y). Model 2 memiliki displacement terbesar yaitu 331.526 mm (X) dan 347.076 mm (Y), serta drift maksimum 31.620 mm (X) dan 33.698 mm (Y). Model 3 menunjukkan hasil terbaik dengan displacement 324.286 mm (X) dan 336.759 mm (Y), serta drift 31.086 mm (X) dan 32.495 mm (Y). Berdasarkan ATC-40, ketiga model berada pada level Immediate Occupancy. Penerapan sistem belt truss dan outrigger dapat diaplikasikan sebagai salah satu teknologi penahan gempa pada struktur supertall building di kawasan seismik seperti Jakarta. The construction of supertall buildings in urban areas such as Jakarta is a solution to land constraints and the increasing need for vertical space. However, the height of these buildings poses a major challenge in withstanding lateral forces caused by earthquakes, requiring an efficient and robust structural system. This study aims to evaluate the effectiveness of belt truss and outrigger systems in reducing displacement and inter-story drift, as well as assessing structural performance based on ATC-40, using the Thamrin Nine Autograph Tower as a case study. The supertall building structure was evaluated using earthquake loading via the response spectrum method, followed by numerical analysis using 3D modeling in ETABS 2020 software. The study includes three models: Model 1 (existing system on floors 35–36 and 55–57), Model 2 (without the system), and Model 3 (system on floors 18–20, 37–39, and 56–57). The analysis results show that Model 2 has the largest displacement, namely 331.526 mm (X) and 347.076 mm (Y), as well as maximum drift of 31.620 mm (X) and 33.698 mm (Y). Model 1 showed displacement of 329.195 mm (X) and 342.202 mm (Y), and drift of 31.224 mm (X) and 33.076 mm (Y). Model 3 shows the best results with a displacement of 324.286 mm (X) and 336.759 mm (Y), and a drift of 31.086 mm (X) and 32.495 mm (Y). Based on ATC-40, all three models are at the Immediate Occupancy level. The application of belt truss and outrigger systems can be implemented as one of the earthquake-resistant technologies for supertall buildings in seismic zones such as Jakarta.
