Abstract

Peningkatan intensitas gempa yang terjadi di wilayah Indonesia selama 11 tahun terakhir menjadi suatu hal yang penting untuk diperhatikan. Dengan intensitas gempa yang meningkat, dikhawatirkan struktur bangunan bertingkat yang telah berdiri saat ini tidak memiliki kinerja seismik yang andal. Dengan demikian, diperlukan suatu metode alternatif dalam peningkatan kinerja seismik suatu struktur, salah satunya yaitu dengan penambahan sistem peredam pasif. Tuned Liquid Damper (TLD) merupakan sistem peredam pasif (tuned passive damper) yang menggunakan gerakan sloshing air dengan arah gerakan berlawanan dengan gerak struktur akibat adanya pergerakan tanah yang terjadi, agar terjadi disipasi energi gempa yang diterima oleh struktur (Cetin & Aydin, 2019). Dalam studi perbandingan ini, Gedung Training Facility Gelora Bung Karno (GBK) menjadi bangunan eksisting yang ditinjau. Gedung Training Facility Gelora Bung Karno (GBK) Jakarta menggunakan struktur beton bertulang konvensional dan Sistem Rangka Momen Khusus (SRMK). Bangunan tersebut akan dimodelkan ulang dengan menambahkan sistem peredam pasif Tuned Liquid Damper (TLD) dengan program bantu ETABS dan Analisis Non-linier Time History. Hasil kinerja seismik setelah struktur ditambahkan Tuned Liquid Damper (TLD) yang diukur berdasarkan kinerja batas layan dan ultimit, menunjukkan adanya reduksi simpangan antar lantai rata-rata berkisar 50% pada arah-X dan 40% pada arah-Y. ================================================================================================= The increase in the intensity of earthquakes that have occurred in Indonesia over the past 11 years is an important matter to note. With the increasing intensity of the earthquake, it is feared that the existing high-rise building structures will not have reliable seismic performance. Thus, an alternative method is needed to improve the seismic performance of a structure, one of which is the addition of a passive damper system. Tuned Liquid Damper (TLD) is a passive damper system (tuned passive damper) that uses the sloshing motion of the water in the opposite direction to the motion of the structure due to soil movement that occurs, so that dissipation of earthquake energy is received by the structure (Cetin & Aydin, 2019). In this comparative study, the Gelora Bung Karno (GBK) Training Facility Building is the existing building being reviewed. The Gelora Bung Karno (GBK) Jakarta Training Facility Building uses a conventional reinforced concrete structure and a Special Moment Resistant Frame System (SRMF). The building will be remodeled using a Tuned Liquid Damper (TLD) passive damping system with the ETABS program and Time History Non-linear Analysis. The results of the seismic performance after the Tuned Liquid Damper (TLD) is added to the structure, which was measured based on the performance of the service limit and the ultimate limit, showed a reduction in displacement between floors of around 50% in the X-direction and 40% in the Y-direction.
