Abstract

Umumnya kolom dibuat dari material beton konvensional, beberapa aspek yang dapat
menjadi perhatian dalam sistem beton konvensional, antara lain waktu pelaksanaanya yang lama,
banyak sisa material yang dihasilkan, kontrol kualitas yang sulit. Sistem beton pracetak ini dibuat
di tempat fabrikasi yang nantinya dapat dikontrol kualitas dan mutunya. Kunci utama
keberhasilan pabrikasi beton pracetak adalah pada desain sambungan. Banyak penelitian telah
dilakukan pada struktur beton bertulang monolitik di bawah efek seismic. Sistem sambungan
poket adalah sambungan kolom-pondasi dengan kolom yang digunakan dalam struktur beton
pracetak dibuat dengan menanamkan bagian kolom (panjang tertanam) ke dalam rongga pondasi.
Ruang antara rongga dan kolom diisi dengan beton cor di tempat.
Tujuan penelitian ini adalah memodelkan kolom beton pracetak mutu tinggi dengan sistem
pocket connection modifikasi panjang tertanam dan mutu tulangan kolom sesuai SNI 2052:2017.
Pemodelan kolom beton pracetak mutu tinggi dengan pocket coneection diberikan beban, yaitu
beban aksial dan beban siklik lateral. Hasil yang dapat disimpulkan bahwa untuk beban axial
model CB1 panjang tertanam 640 mm memiliki kapasitas beban yang lebih besar daripada model
CB2 panjang tertanam 800 mm . Namun untuk beban siklik lateral model CB2 panjang tertanam
800 mm memiliki disipasi energi yang lebih baik daripada model CB2 panjang tertanam 800 mm.
================================================================================================
Generally, columns are made from conventional concrete materials, which present several
concerns such as long construction times, significant residual material production, and
challenging quality control. Precast concrete systems, however, are manufactured at a fabrication
site where both quality and consistency can be more effectively managed. The key to successful
precast concrete manufacturing lies in the design of the connections. Numerous studies have
examined monolithic reinforced concrete structures under seismic effects. The pocket connection
system is a type of column-foundation connection used in precast concrete structures. It involves
embedding column sections (with specific embedded lengths) into a foundation cavity, which is
then filled with cast-in-place concrete.
The aim of this research is to model high-quality precast concrete columns using a pocket
connection system, modifying the embedded length and the quality of column reinforcement
according to SNI 2052:2017. The modeling involves subjecting the columns to both axial loads
and lateral cyclic loads. The results indicate that, for axial loads, the CB1 model with an
embedded length of 640 mm has a greater load capacity compared to the CB2 model with an
embedded length of 800 mm. However, for lateral cyclic loads, the CB2 model with an embedded
length of 800 mm demonstrates better energy dissipation compared to the CB1 model with an
embedded length of 640 mm.
