“…This study has been done using a finite element (FE) based computer program, namely Abaqus® by utilizing the CDP model to model the nonlinear behavior of concrete [20]. All specimen models were analyzed following the modeling principles carried out in previous research [16], [17], [21]. The modeling parameters were previously validated using experimental tests [3] to obtain the appropriate parameter values.…”

“…In addition, the crack patterns shown in the experimental specimen are similar to the strain contours of the analysis results. Comparing the results obtained from analysis and experimental, it assumes that the modeling technique and the validated material parameters can resemble the experimental results [16], therefore will be applied to further study of hoop variations.…”

“…Experimental testing is still a priority to get actual results, but the cost is quite expensive to test the effect of one parameter. The development of information technology both software and hardware make it possible to perform a numerical approach in investigating the effect of several parameters [15], [16], [17]. Numerical research using finite element-based software regarding column confinement has been carried out and obtained comprehensive results [18], [19].…”

This numerical study is done to evaluate the effect of confinement on the axial capacity and ductility of thin section columns using the plastic damage plasticity (CDP) model in Abaqus. Seven specimens of short columns with the size of 100x400x300 mm subjected to uniaxial compression loads were analyzed based on material parameters and modeling technics that were first validated using an experimental specimen. The variation in confinement was made by changes in the configurations of the column hoops giving the variation on the hoops volumetric ratios such as 1,06% (C1), 1,16% (C2), 1,25% (C3),1,34% (C4), 1,69% (C5), 1,25% (C6) and 2,02% (C7). All specimen models have longitudinal rebars of 10D13 (As = 1327 mm2) and hoops Ø5.6 with a yield strength of 437 MPa and 284 MPa, respectively. The compressive concrete strength of 21,5 MPa was considered according to the tested specimen for validation. The validated results show that the finite element analysis can predict well the behaviors of the tested column specimen in terms of stress on concrete, reinforcement, and the crack pattern. The analysis results of the hoops parameters show that increasing the hoops' volumetric ratio can increase the capacity of the concrete core but not the column's ductility. The maximum increase in the column capacity of 87.15% occurs in specimen C4 with the hoops volumetric ratio of 1,34% and the lowest of 58.14% occurs in specimen C3 with the hoops volumetric ratio of 1,25%. The specimen model C7 with the highest hoops volumetric ratio of 2.02% increases the capacity by only 65.27%. The effectiveness of confinement is not only determined by the higher values of the hoops' volumetric ratio but also by the proper configurations of the hoops to obtain effective confining effects on the concrete core.

Penggunaan material komposit dalam dunia konstruksi telah mengarah kepada penggunaan Concrete-Filled Tubes (CFT). Selain secara eksperimental, dengan meningkatnya perkembangan teknologi dan formulasi elemen hingga memungkinkan dilakukan penelitian secara analitik melalui aplikasi berbasis metode elemen hingga (FEM). ABAQUS dengan fitur Concrete Damage Plasticity, dapat digunakan untuk pemodelan keruntuhan beton yang mampu memprediksi perilaku inelastisnya. Dengan aplikasi ini, interaksi antar elemen dimodelkan dengan surface to surface contact dengan friction coeffition beton dan baja sebesar 0,2, sedangkan baja dan baja sebesar 0,1. Beban aksial diaplikasikan secara konstan pada bagian bebas yang diikuti dengan beban lateral siklik yang mengacu pada SNI 7834-2012. Studi pengaruh ketebalan baja dan eksentrisitas gaya lateral dilakukan dengan menggunakan true stress dan true strain sebagai input aplikasi. Hasil yang diperoleh menunjukkan bahwa peningkatan ketebalan baja hingga 50% dapat meningkatkan kapasitas beban, kapasitas drift, dan daktilitas. Peningkatan ketebalan baja juga dapat memperkecil panjang sendi plastis dan distribusi tegangan maksimum pada kolom CFT. Sedangkan, hasil uji eksentrisitas gaya lateral hingga 400 mm menghasilkan kecenderungan terbalik dengan peningkatan ketebalan baja, tetapi distribusi tegangan maksimum juga terjadi pada kolom CFT. Dari hasil validasi analisis FEM memberikan prediksi yang baik dengan keakuratan diatas 95% dan pola keruntuhan yang menyerupai hasil uji eksperimental.
