“…The advantages of using spun piles are high strength and quality, longer durability, and more economical and practical in its implementation. In addition to the benefits, spun pile also has drawbacks in its use, that as low energy IOP Publishing doi:10.1088/1755-1315/1244/1/012012 2 absorption and failure patterns due to seismic loads in the form of brittle failure that occurs suddenly [3]- [6]. Efforts to increase the strength and ductility of the spun pile have been carried out by researchers, among others, by filling the spun pile hole with concrete, then wrapped with carbon fiber [7], and by external restraint using fiber-reinforced polymer (FRP) [8].…”

This paper discusses the behaviour of the slab-on-pile (SOP) structure with variations support end interconnection under earthquake loads. Analysis of the SOP structure using macro modelling of numerical analysis. The SOP structure model is developed with three variations of the model with different support conditions, namely Model 1 with the end of the structure attached to the pile head and spun pile, Model 2 with the end of the structure attached to roller support, and Model 3 with the end of the structure not being supported, or the same as the cantilever system. Earthquake load is assigned using two methods according to SNI 2833:2016, namely the Single-mode Spectra Method and the Response Spectrum Method. Based on the analysis results, the vibration period of the SOP structure calculated by the single mode spectra method is 0.60 seconds for the first mode and 0.34 seconds for the second mode. Based on the numerical analysis results, the vibration period of Model 3 is greater than that of other models. The maximum internal forces and the most significant displacement occur in Model 3, while the most considerable base reaction occurs in Model 1. The magnitude of the base shear force occurs because Model 1 uses more piles, thus increasing the stiffness of the structure. This results in an increase in seismic forces but reduces displacement of the structure. Furthermore, for the analysis and design of SOP structures, Model 3 is the most reliable because this model produces the maximum load effect and the most significant displacement of the structure.

“…Fiber-based finite element analysis (FB-FEA) is a numerical technique frequently used to develop nonlinear PSW models due to the accuracy of the results [10][11][12][13]. This technique has been extensively validated for its ability to accurately reproduce experimental results [14][15][16].…”

Fiber-based finite element analysis (FB-FEA) has been widely recognized for its ability to reproduce experimental results and is also a reliable method for evaluating the nonlinear seismic response of pile-supported wharves (PSWs). Design practice often employs frame analysis (FA) due to its easy implementation. To precisely reproduce the nonlinear seismic response of PSW using FA, it is necessary to configure mechanical properties such as the hinge property correctly. However, it is unclear whether the hinge properties proposed in previous studies can be applied to PSWs with spun piles. In this study, a novel FA method was developed to investigate the nonlinear seismic response of PSWs with corroded spun piles considering PC bar area reduction, deteriorated material properties, the bending stiffness reduction factor, and the moment–curvature relationship of the spun pile. The nonlinear seismic response of corroded PSWs was determined by performing pushover analysis using three methods: FA using the method of the previous study (FA-1), the proposed FA method (FA-2), and FB-FEA. As regards PSW foundations, vertical pile and batter pile configurations were considered. The pushover analysis results were compared in terms of several parameters, such as the natural period, plastic hinge formation, and load capacity of the corroded PSWs. The FA-2 results agreed very well with the FB-FEA results, while the FA-1 results were less precise with respect to the natural periods and load capacities of corroded PSWs. The results indicated that the bending stiffness reduction factor, moment–curvature relationship, and axial load–bending moment (P–M) capacity of the corroded spun piles should be appropriately defined. Corrosion had greater negative impacts on the compressive axial load and bending moment capacities of the spun pile than on its tensile axial load capacity.

“…Namun, peningkatan beban aksial juga dapat meningkatkan kapasitas momen (crack, yielding, dan ultimate). Penelitian numerik pemodelan spun pile dilakukan untuk mencari pemodelan finite element (FE) yang tepat menggunakan software OpenSees agar dapat merepresentasikan kondisi sesungguhnya (Setiawan et al, 2020). Penambahan perkuatan sambungan spun pile-pile cap dengan steel jacket dapat disimulasikan secara numerik.…”

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.
