“…Hence the seismic performance of spun pile also increases and thus the spun pile can be used in areas with moderate earthquake risk. Bang [3] studied about the effect of modified transverse reinforcement in the concrete infill that could increase ductility of the structure and avoid shear failure. Moreover, spun pile without steel anchorage against the pile cap had undergone brittle failure.…”

“…Performance based design has been widely used on the upper structure design which allows structure to behave inelastic during severe earthquake. The design concept has been adopted on the substructure in several countries based on results of previous research of spun pile-to-pile cap connections [17], [3], [14], [16]. Ductility is one of the critical parameters to ensure that the structure can behave inelastic during seismic.…”

Numerical study was conducted by using ABAQUS software to investigate two issues on spun pile connections. The issues are usage of non-shrinkage concrete infill cast inside hollow of pile and ductility. An experimental test was carried out to investigate the effect of two different concrete infill types which were common concrete fc’ 35 MPa and non-shrinkage concrete fc’ 54 MPa. A finite element model was validated against experimental test. The results were compared in terms of hysteresis curve, ductility, and performance level. Ductility is one of the important parameters to describe performance of spun pile connections under seismic load. There are different approaches to calculate ductility and this leads to four different ductility values. Hence, ductility of spun pile with concrete infill is in the range of 3.2 to 4.8. Behavior of spun pile with non-shrinkage concrete infill is slightly improved although the results were almost similar.

“…The reason for the widely used of spun piles are because of the lower cost and the high bearing capacity of spun piles. One of the most important components that need to be considered is the connection between spun piles and pile cap, where as in this region the change of area, stress, and stiffness occurred suddenly [2]. The connection region experienced a high curvature if were designed as fixed head.…”

The confinement ratio of spun piles manufactured in Indonesia has been a matter of concern since it does not meet the applicable requirements. Additional steel jacketing retrofitting was used to cope with the problem as well as improve the strength of spun pile to pile cap connection. A numerical study was performed to study the effect of steel jacketing on a spun pile with concrete infill reinforcement. Furthermore, a parametric study was conducted to study the effect of steel jacketing length to spun pile behaviour. Pushover analysis using the Opensees software will be performed with a monotonic loading approach. The results were compared in terms of load – displacement curve, shear and bending capacity, and displacement ductility. It is found that the presence of steel jacketing provides a better behaviour and significantly increases the ductility of specimens. The study also found that a minimum length 1.5D of steel jacketing retrofitting was necessary for better results and remain easily repairable for future concerns.

“…Spun pile merupakan salah satu jenis fondasi yang paling banyak digunakan pada jembatan dan dermaga. Penelitian-penelitian terdahulu menunjukkan bahwa sambungan antara pile dan pile cap adalah lokasi yang cukup rawan karena terjadinya perubahan kekakuan yang cukup drastis dari pile cap ke pile (Bang, 2016). Area pertemuan ini mengalami gaya dalam moment (high curvature) terbesar terutama jika sambungan antara tiang dan pile cap didisain sebagai fixed head.…”

“…Hasil studi eksperimen mendapatkan sambungan memiliki daktilitas pada rentang 1,99-3,03. Penelitian lainnya dilakukan di Korea, mencoba memperbaiki daktilitas dan kekuatan sambungan spun pile-pile cap dengan memberikan improvement berupa penambahan tulangan sengkang pada spun pile dan memberi variasi jenis Teras Jurnal, Vol 12, No 1, Maret 2022P-ISSN 2088-0561 E-ISSN 2502-1680 sambungan spun pile dan pile cap (Bang, Jin-Wook et al, 2016). Hasil studi menunjukkan bahwa kekakuan rotasi inisial pada sambungan dipengaruhi oleh kedalaman penetrasi spun pile ke pile cap dan kedalaman penjangkaran tulangan.…”

Berdasarkan SNI 8460, spun pile sebagai struktur bawah didesain belum menggunakan konsep performance-based design (PBD) karena pertimbangan sulitnya proses perbaikan, meskipun PBD sudah diperbolehkan di negara lain. Peta gempa tahun 2017 menunjukkan adanya peningkatan seismic demand di Indonesia yang menyebabkan desain fondasi yang tidak efisien jika perilaku inelastic pada pondasi akibat gempa besar tidak diperbolehkan. Untuk mempelajari perilaku inelastic pondasi, tiga sambungan spun pile berukuran full scale diuji dengan pembebanan siklik horizontal. Analisis lanjutan dengan finite element (FE) dilakukan menggunakan Abaqus. Karena kurangnya jumlah tulangan geser (spiral) pada spun pile yang ada di Indonesia, efek confinement dari pemodelan tulangan spiral dibandingkan dengan pemodelan jika spiral disederhanakan sebagai hoops. Analisis FE juga dilakukan untuk mempelajari perbandingan perilaku antara spun pile kosong dan dengan beton pengisi dalam hal kekuatan, daktilitas dan performance levels dari sambungan spun pile.
