ABSTRAKPada umumnya Bangunan yang ada di Indonesia telah dibangun dengan
acuan pedoman SNI 1726-1989-F dan SNI 03-1726-2002, telah lahir peraturan
baru SNI 03-1726-2010. Bangunan yang telah ada boleh jadi tidak memenuhi
standar baru, sehingga harus diperkuat (retrofitting). untuk mendapatkan sistem
struktur dengan respon yang paling baik terhadap gempa dilakukan studi
pengembangan analisis mengenai perilaku BRB. Bresing tipe ini diaplikasikan
pada bangunan tinggi struktur beton bertulang. Penelitian terlingkup mengenai,
mekanisme, kinerja, dan parameter-parameter aktualnya terkait dengan adanya
pengaruh gempa rencana sesuai FEMA 356. Hal-hal tersebut diteliti dengan
membandingkan antara struktur eksisting, dengan struktur hasil retrofitting-nya.
Hasil penelitian menunjukkan bahwa hasil analisa statik nonlinier (pushover
analysis) untuk struktur sistem ganda (DS) dengan BRBS sampai pada target
peralihan (performance point) yang dihitung berdasarkan FEMA 356 struktur
gedung yang didesain masih memiliki taraf kinerja Life safety.
Abstract In general, the existing building in Indonesia has been constructed with
reference to the guidelines SNI 1726-1989-F and SNI 03-1726-2002, along with
expanding knowledge of the new regulations have been born SNI 03-1726-2010.
Existing buildings may be not meeting the new standards, so the buildings are
vulnerable to safety and rigidity of the structure. To that end, should be
strengthened (retrofitting). To get the system structure with the best response to
the earthquake made the development of analytical studies on the behavior of
BRB. Bracing is applied to the type of reinforced concrete structures in tall
buildings. The study included about mechanisms, performance and actual
parameters associated with the influence of earthquake plans with FEMA 356.
Those things are investigated by comparing the existing structure with its
retrofitting the structure. The results showed that the results of nonlinear static
analysis (pushover analysis) for the structure of the dual system (DS) with BRBS
to the intermediate targets (performance point) are calculated based on FEMA
356, designed the building structure still has the Life Safety performance level.
This indicates that the building is designed according to the performance already
qualified FEMA 356 because the building is designed as an office building.
