Abstract
Pertumbuhan jumlah penduduk pada suatu wilayah semakin
meningkat dalam setiap tahunnya sehingga perlu adanya sarana
tempat tinggal bagi penduduk. Namun, keterbatasan lahan yang
tersedia berbanding terbalik dengan pertumbuhan jumlah
penduduk sehingga pembangunan apartemen menjadi salah satu
jawaban atas permasalahan tersebut dikarenakan apartemen
adalah sarana tempat tinggal yang ideal untuk wilayah yang
memiliki keterbatasan lahan, dikarenakan tipe konstruksinya
adalah bangunan gedung tinggi. Apartemen harus didesain
fungsional, ekonomis, dan tahan terhadap gempa. Oleh karena itu,
salah satu alternatif dalam menjawab permasalahan diatas adalah
dengan merencanakan struktur baja beton komposit dengan sistem
Buckling-Restrained Braced Frames (BRBF).
Struktur komposit adalah struktur yang menggabungkan
komposisi 2 material atau lebih dengan sifat yang berbeda
sehingga membentuk satu kesatuan struktur yang memiliki sifat
gabungan yang lebih baik. Untuk menahan gempa, direncanakan
juga sistem Buckling-Restrained Braced Frames. Buckling-
Restrained Braced Frames (BRBF) adalah sistem struktur rangka
baja yang mempunyai ciri khas “profil anti-tekuk”, dimana profil
ini mempunyai kekakuan elastis yang sangat baik, daktilitas tinggi,
dan penyerapan energi yang sangat tinggi.

Dalam tugas akhir ini, Gedung Apartemen Arundaya Tower
B yang semula menggunakan struktur beton bertulang dan dinding
geser setinggi 52 lantai akan dimodifikasi ulang dengan
pengurangan lantai menjadi 25 lantai menggunakan struktur
komposit dan sistem BRBF yang menggunakan konfigurasi
multistory X-bracing. Studi literatur yang digunakan dalam
proposal ini mengacu kepada peraturan SNI 1727:2020, SNI
1726:2019, SNI 1729:2020, AISC 341-16, ACI 318-19, buku ajar
dan jurnal yang berkaitan dengan struktur komposit dan sistem
BRBF.
Dari hasil analisa yang telah dilakukan, diperoleh hasil
yaitu: plat atap, ruang hunian, cafetaria, gimnasium, dan ruang
mesin memiliki ketebalan 9 cm. Dimensi balok induk WF
500x200x10x16, dimensi kolom terbesar CFT 700.700.25. Dimensi
bracing BRBF cross-section 150.15 dengan casing HSS
250.250.16. Pondasi menggunakan kedalaman 22 m menggunakan
spun pile dengan diameter 80 cm, dimensi kolom pedestal 0,9x0,9
m, dimensi pilecap 3,6x3,6x1,2 m dan dimensi sloof 40x60 cm.

=========================================
Population growth in an area is increasing every year so it
is necessary to have housing facilities for residents. However, the
limited land available is inversely proportional to population
growth so that the construction of apartments is one of the answers
to these problems because apartments are an ideal place to live for
areas that have limited land, because the type of construction is
high-rise buildings. Apartments must be designed to be functional,
economical, and resistant to earthquakes. Therefore, one
alternative in solving the problems is to plan a steel-concrete
composite structure with a Buckling-Restrained Braced Frames
(BRBF) system.
Composite structure is a structure that combines the
composition of 2 or more materials with different properties so as
to form a unified structure that has better combined properties. To
withstand the earthquake, a Buckling-Restrained Braced Frames
system is also planned. Buckling-Restrained Braced Frames
(BRBF) is a steel frame structure system that has the characteristic
“anti-buckling profile”, where this profile has excellent elastic
stiffness, high ductility, and very high energy absorption.
In this final project, the Arundaya Tower B Apartment
Building which originally used a reinforced concrete structure and
a shear wall as high as 52 floors will be re-modified by reducing
the floor to 25 floors using a composite structure and a BRBF
x
system that uses a multistory X-bracing configuration. The
literature study used in this proposal refers to the regulations of
SNI 1727:2020, SNI 1726:2019, SNI 1729:2020, AISC 341-16,
ACI 318-19, textbooks and journals related to composite structures
and BRBF systems.
From the results of the analysis that has been carried out,
the results obtained are: the roof plate, residential room, cafeteria,
gymnasium, and engine room has a thickness of 9 cm. The
dimensions of the WF main beam are 500x200x10x16, the largest
column dimension is CFT 700,700.25. Dimensions of bracing
BRBF cross-section 150.15 with HSS casing 250.250.16. The
foundation uses a depth of 22 m using a spun pile with a diameter
of 80 cm, pedestal column dimensions 0.9x0.9 m, pilecap
dimensions 3.6x3.6x1.2 m and sloof dimensions 40x60 cm.
