“…The geometrical nonlinearity was taken in account to obtain the nonlinear behavior of the FE model. In this study, the period time of each load cycle was set to 4 s, which was adopted from other numerical study [27]. Thus, the total time of cycles was 228 s. The automatic incrimination with an increment size of 0.1 s was considered for the initial and maximum phases of the step to achieve smooth and uniform increments as well as avoiding the convergence problems [27].…”

“…Kolom tabung baja terisi beton atau Concrete Filled Steel Tube (CFST) umumnya lebih diminati daripada kolom beton bertulang atau Reinforced Concrete (RC) dan kolom baja konvensional karena beberapa keunggulannya seperti kekuatan, daktilitas, dan kekakuan yang lebih tinggi [1]. Beton inti dapat meningkatkan kekakuan tabung baja dan mengurangi risiko tekuk global maupun tekuk lokal.…”

“…Song et al [9] explored load introduction and transfer mechanisms in K-type connections in steel-encased CFSTs, while Zhou et al [10] brought innovation to the design of circular 2 of 23 CFST pier connections known as CECCs. Xu et al [11] proposed a novel anchor-rebarcolumn-foundation connection (SAC) tailored for CFST columns, and M. Ansari et al [12] undertook a numerical analysis of the performance of a rib stiffener steel beam connected to a circular CFST column under cyclic loading conditions. Additionally, Lei et al [13] introduced a novel fully welded concrete-filled integral K-joint with longitudinal preformed ribs to enhance fatigue performance, and Sun et al [14] delved into the local and post-local buckling behavior of welded square high-strength steel tubes with concreteinfilled restraints.…”

For this study, we conducted a detailed examination and comprehensive comparative analysis of the structural responses and mechanical behavior of bolted sleeve connections in precast circular semi-continuous steel tubular concrete (PCSCFST) columns. The research involved fourteen specimens, and we considered the impacts of various parameters, including eccentricity, external steel sleeve thickness, bolt diameter, and slenderness ratio. The findings revealed that the external steel sleeve significantly enhances the protection of the connection area, enabling the bolts to effectively withstand eccentric loads. However, sleeves that are too thick may lead to premature bolt failure, reducing their ultimate load-bearing capacity. Using bolts to transfer loads to the concrete significantly strengthens the restraining effect of the steel sleeve. Nonetheless, increasing the bolt diameter beyond a certain threshold may diminish this beneficial impact, potentially leading to connection failure and a decrease in ultimate load-bearing capacity. A new ‘cooperative value q’ measures component collaboration at ultimate capacity, showing that shorter columns offer less effective coordination than longer ones. Through regression analysis, we formulated a prediction for axial ultimate bearing capacity, closely aligning with the experimental data (Npre-a/Nu average value of 1.003, variance 0.00248). Three N–M curves, including the Eurocode 4 method, offered conservative predictions, with Eurocode 4 closely matching the experimental results. A refined prediction method following Eurocode 4 was developed, yielding an average Ppre-U/Pu value of 0.971 and a variance of 0.0107.
