ABSTRAKSemakin bertambahnya kebutuhan ruang vertikal di kota besar seperti Jakarta
membuat para ahli membangun banyak bangunan bertingkat. Meski demikian,
rencana ini tidak selalu efektif oleh karena keberadaan bangunan purbakala
(heritage) yang harus dilestarikan. Oleh karena itu, bangunan baru harus dibangun
menggunakan sistem transfer yang dalam penelitian ini berupa kombinasi antara
balok transfer prategang parsial dan kolom-kolom pendukung. Analisa pushover
akan dilakukan untuk bangunan ini sehingga kinerja bangunan pada fase inelatis
dapat diketahui. Hasil bangunan sistem transfer akan dibandingkan dengan hasil
analisa pushover pada bangunan regular untuk mengetahui pengaruh keberadaan
sistem transfer terhadap kinerja inelastik struktur. Sebelum dilakukan analisa
pushover, bangunan didesain secara dinamik linear dengan mengacu pada
peraturan SNI 03-1726-2012 dan SNI 03-2847-2002. Hasil perbandingan
menunjukkan pertambahan degree of prestressing akan memperkecil daktilitas
dan kemampuan disipasi energi bangunan. Rasio pengurangan kemampuan
disipasi energi bervariasi antara 15% - 23%. Kinerja terendah seluruh bangunan
pada saat target perpindahan ialah Life Safety, yang mana merupakan level kinerja
Basic Safety Objectives berdasarkan FEMA 356. Dari sini dapat ditarik
kesimpulan bahwa peraturan yang digunakan dalam desain mampu menghasilkan
bangunan dengan performa cukup baik.
ABSTRACTThe increasing need of vertical room in Jakarta made experts build a lot of multistories
buildings. Nonetheless, this plan is not always effective because of the
presence of heritage building which must be preserved. Consequently, new
building must be built using a transfer system which in this research is a
combination between partially prestressed transfer beam and supporting columns
below the beam. To determine the inelastic performance of the building, pushover
analysis will be applied. The pushover analysis result for transfer system building
later will be compared with the result for regular building to understand the effect
of transfer system to structure?s inelastic performance. Prior to applying pushover
analysis, both buildings are designed based on SNI 03-1726-2012 and SNI 03-
2847-2002 codes. The comparison shows the degree of prestressing accretion will
reduce the ductility and energy dissipation capacity of the building. The reduction
of energy dissipation capacity ratio varies between 15% - 23%. The lowest
performance of both buildings at target displacement is Life Safety, which is the
Basic Safety Objectives performance based on FEMA 356. From this, it can be
concluded that the codes used in designing the building is able to produce
building with quite good performance., The increasing need of vertical room in Jakarta made experts build a lot of multistories
