Abstract

Indonesia terletak di kawasan ring of fire dan pertemuan tiga lempeng tektonik, sehingga memiliki potensi tinggi terhadap gempa bumi, termasuk gempa megathrust dan pergerakan sesar aktif. Dampak getaran gempa bervariasi tergantung pada karakteristik struktur dan jenis tanah. Oleh karena itu, penting merancang struktur bangunan yang memiliki kekuatan dan kekakuan memadai agar tetap berdiri meskipun berada di ambang keruntuhan. Penelitian ini bertujuan untuk menilai ketahanan struktur terhadap beban gempa dan mengetahui level kinerja struktur berdasarkan nilai perpindahan. Pembebanan yang digunakan dalam penelitian ini menggunakan metode respons spektrum, metode statik ekuivalen, dan metode pushover. Pemodelan struktur dalam penelitian ini menggunakan bantuan program ETABS18. 1. Hasil analisis menunjukkan simpangan dan perpindahan maksimum struktur berbeda pada tiap metode. Analisis respon spektrum menghasilkan simpangan 37.461 mm (x) dan 51.893 mm (y), statik ekuivalen 44.594 mm (x) dan 56.722 mm (y), serta pushover 64.246 mm (x) dan 63.509 mm (y). Perpindahan maksimum tercatat 55.982 mm (x) dan 66.852 mm (y) pada respon spektrum, 63.590 mm (x) dan 75.510 mm (y) pada statik ekuivalen, serta 85.238 mm (x) dan 84.600 mm (y) pada pushover. Analisis pushover juga menghasilkan performance point dengan gaya geser 56,270.2575 kN dan perpindahan 461.685 mm (x), serta gaya geser 49,926.4545 kN dan perpindahan 565.955 mm (y). Berdasarkan ATC-40 dan FEMA-440, kinerja Gedung Presisi 3 Mabes Polri berada pada level Immediate Occupancy (IO), sehingga struktur tetap aman dan dapat difungsikan kembali setelah gempa. Indonesia is located in the Ring of Fire and at the intersection of three tectonic plates, making it highly prone to earthquakes, including megathrust earthquakes and active fault movements. The impact of earthquake vibrations varies depending on the characteristics of the structure and soil type. Therefore, it is important to design buildings with sufficient strength and rigidity to remain standing even when on the verge of collapse. This study aims to assess the structural resistance to earthquake loads and determine the structural performance level based on displacement values. The loading methods used in this study include the response spectrum method, the equivalent static method, and the pushover method. Structural modeling in this study was conducted using the ETABS18 program. 1. The analysis results show that the maximum deflection and displacement of the structure vary across each method. The response spectrum analysis yielded displacements of 37.461 mm (x) and 51.893 mm (y), the static equivalent method yielded 44.594 mm (x) and 56.722 mm (y), and the pushover method yielded 64.246 mm (x) and 63.509 mm (y). The maximum displacements recorded were 55,982 mm (x) and 66,852 mm (y) in the spectrum response, 63,590 mm (x) and 75,510 mm (y) in the equivalent static response, and 85,238 mm (x) and 84,600 mm (y) in the pushover response. The pushover analysis also yielded performance points with a shear force of 56,270.2575 kN and a displacement of 461.685 mm (x), as well as a shear force of 49,926.4545 kN and a displacement of 565.955 mm (y). Based on ATC-40 and FEMA-440, the performance of the Precision Building 3 at the Indonesian National Police Headquarters is at the Immediate Occupancy (IO) level, meaning the structure remains safe and can be reoccupied after an earthquake.
