ABSTRAK
Pada umumnya Bangunan yang ada di Indonesia telah dibangun denganacuan pedoman SNI 1726-1989-F dan SNI 03-1726-2002, telah lahir peraturanbaru SNI 03-1726-2010. Bangunan yang telah ada boleh jadi tidak memenuhistandar baru, sehingga harus diperkuat (retrofitting). untuk mendapatkan sistemstruktur dengan respon yang paling baik terhadap gempa dilakukan studipengembangan analisis mengenai perilaku BRB. Bresing tipe ini diaplikasikanpada bangunan tinggi struktur beton bertulang. Penelitian terlingkup mengenai,mekanisme, kinerja, dan parameter-parameter aktualnya terkait dengan adanyapengaruh gempa rencana sesuai FEMA 356. Hal-hal tersebut diteliti denganmembandingkan antara struktur eksisting, dengan struktur hasil retrofitting-nya.Hasil penelitian menunjukkan bahwa hasil analisa statik nonlinier (pushoveranalysis) untuk struktur sistem ganda (DS) dengan BRBS sampai pada targetperalihan (performance point) yang dihitung berdasarkan FEMA 356 strukturgedung yang didesain masih memiliki taraf kinerja Life safety.
Abstract
In general, the existing building in Indonesia has been constructed withreference to the guidelines SNI 1726-1989-F and SNI 03-1726-2002, along withexpanding knowledge of the new regulations have been born SNI 03-1726-2010.Existing buildings may be not meeting the new standards, so the buildings arevulnerable to safety and rigidity of the structure. To that end, should bestrengthened (retrofitting). To get the system structure with the best response tothe earthquake made the development of analytical studies on the behavior ofBRB. Bracing is applied to the type of reinforced concrete structures in tallbuildings. The study included about mechanisms, performance and actualparameters associated with the influence of earthquake plans with FEMA 356.Those things are investigated by comparing the existing structure with itsretrofitting the structure. The results showed that the results of nonlinear staticanalysis (pushover analysis) for the structure of the dual system (DS) with BRBSto the intermediate targets (performance point) are calculated based on FEMA356, designed the building structure still has the Life Safety performance level.This indicates that the building is designed according to the performance alreadyqualified FEMA 356 because the building is designed as an office building. |
