Gedung administrasi fakultas teknik universitas syiah kuala selesai pada tahun 1998. oleh karena itu perlu dievaluasi ulang mengikuti standar peraturan gedung terbaru yaitu sni 1726:2019. penelitian bertujuan untuk mengevaluasi perilaku struktur bangunan setelah masa layan 24 tahun yaitu berupa perpindahan (displacement), gaya dasar (base shear), dan level kinerja struktur sesuai asce 41-17. gedung yang di tinjau dalam penelitian ini adalah gedung administrasi fakultas teknik universitas syiah kuala (usk) yang 3 lantai. gedung ini memiliki panjang 29,4 meter, lebar 13 meter dan tinggi 14,4 meter. pada penelitian ini digunakan analisis pushover dibarengi dengan pengecekan frekuensi alami gedung existing untuk membandingkan perilaku struktur di awal desain gedung terhadap kondisinya saat ini. pemodelan menggunakan program etabs. dari hasil evaluasi didapatkan bahwa level kinerja gedung sesuai perencanaan awal berdasarkan push x yaitu immediate occupancy dan push y termasuk ke dalam life safety. kemudian level kinerja gedung setelah masa layan 24 tahun berdasarkan push x dan push y keduanya termasuk ke dalam kategori life safety yang menyatakan bahwa kerusakan pasca gempa yang mencakup kerusakan pada komponen struktural tetapi tetap memiliki batas terhadap awal keruntuhan sebagian atau total. dari segi kekakuan gedung dalam menahan perpindahan akibat beban pushover juga mengalami penurunan setelah 24 tahun, hal ini bisa diketahui dengan base shear yang sama perpindahan gedung setelah masa layan 24 tahun lebih jauh dibandingkan gedung yang sesuai dengan perencanaan awal.

The Administration Building of the Faculty of Engineering, Syiah Kuala University was completed in 1998. Therefore it needs to be re-evaluated following the latest building regulatory standards, namely SNI 1726: 2019. The research aims to evaluate the behavior of building structures after a service life of 24 years, namely displacement, base shear, and structural performance levels according to ASCE 41-17. The building reviewed in this study is the Administration Building of the Faculty of Engineering, Syiah Kuala University (USK), which has 3 floors. This building is 29.4 meters long, 13 meters wide and 14.4 meters high. In this study, pushover analysis was used accompanied by checking the natural frequency of the existing building to compare the behavior of the structure at the beginning of the building's design to its current condition. Modeling using the ETABS program. From the evaluation results, it was found that the building performance level was in accordance with the initial planning based on push x, namely immediate occupancy and push y included in life safety. Then the performance level of the building after a service life of 24 years based on push x and push y are both included in the life safety category which states that post-earthquake damage includes damage to structural components but still has limits to initial partial or total collapse. In terms of the stiffness of the building in resisting displacement due to pushover loads it also decreased after 24 years, this can be seen with the same base shear the displacement of the building after a service life of 24 years is further than the building according to the initial plan.
