Abstract ：
奥氏体不锈钢S35657因高强度与低合金成本的特点而更适合用作结构钢,但其应用于钢管混凝土柱的研究有待深入.为了研究S35657不锈钢管混凝土柱压弯性能,以截面类型(圆形、方形)、长细比(22、26、43、50)及偏心距(0、40、60 mm)为主要参数,完成16根钢管混凝土柱压弯试验.结果表明:S35657不锈钢管混凝土柱的破坏模态与传统Q355碳钢柱类似,但压弯承载力较碳钢管混凝土柱提高约12％,且压弯承载力均随偏心距与长细比的增加而降低;目前既有规范(规程)对该类柱压弯承载力预测结果偏于保守.建立有限元分析模型并基于试验结果验证其适用性,继而通过验证的模型展开参数分析考察混凝土强度、含钢率和长细比对S35657不锈钢管混凝土柱承载力的影响,分析结果表明:构件稳定系数随着长细比与含钢率的增大而减小,混凝土强度对其影响不大;长细比、含钢率以及混凝土强度对相对轴力-相对弯矩相关曲线影响较大.基于参数分析结果,修正了T/CECS 952-2021《不锈钢管混凝土结构技术规程》中所推荐压弯承载力的计算方法,修正后的简化计算方法对压弯承载力的预测精度提高了约25％.

Abstract ：
Owing to their exceptional durability, reinforced sea-sand concrete-filled (square) stainless steel tubular (RSCFSST) columns present a viable structural solution for coastal regions. Axial compressive tests were conducted on eight square RSCFSST short columns and two sea-sand concrete-filled (square) stainless steel tubular counterparts. The experimental results demonstrated that the incorporation of stainless steel rebars increased their axial compressive resistance, peak strain, and ductility by 4-13 %, 21-52 %, and 25-122 %, respectively. Notably, RSCFSST column filled with sea-sand concrete exhibited comparable axial compressive behavior to those columns utilizing normal concrete. A finite element model was developed to conduct the mechanism and parametric analyses. The mechanism analysis revealed that stainless steel outperformed carbon steel in improving both the peak strain and ductility of the composite columns. Parametric analysis indicated that increasing the concrete strength, 0.2 % proof strength of the steel tube, 0.2 % proof strength of stirrups, steel tubular ratio, or stirrup ratio significantly enhanced the axial compressive resistance of the RSCFSST columns. Finally, novel predictive methods were developed for estimating their axial compressive resistances and peak strains, demonstrating superior accuracy in predictions.

Abstract ：
To meet the critical construction challenges in mountainous and offshore areas, a novel concrete-filled sleeveconnected stainless steel tubular column (sleeve-connected CFSST) is developed by manufacturing the stainless steel tubes in controlled length for convenient transport and assembling on-site with sleeve connection. The spliced steel tubes can further act as formwork to fill on-site mixing concrete for efficient composite action. In this study, the failure modes, load-carrying capacity and ductility of sleeve-connected CFSST columns under axial compressive loading are experimentally investigated with different spliced types. The test results indicates that the outer sleeve can provide additional confinement, leading to strength and ductility enhancement in sleeveconnected CFSSTs. Then finite element (FE) model is validated by the test data, the load-transfer mechanism and confinement effect in typical spliced CFSST columns are systematically analysed by the verified FE model, demonstrating that the existence of core concrete has positive effect on spliced steel tube in transferring axial load and providing additional confinement. Furthermore, the existing design codes give conservative predictions in load-carrying capacity of sleeve-connected CFSSTs. Based on parameter analysis, current predicted methods in cooperation with suggested influenced factor is proposed for compression capacity prediction. Meanwhile, several design recommendations are also delivered within a limited scope.

Abstract ：
The influences of embedded carbon profiled steel (CPS), eccentricity and slenderness ratio on steel-reinforced concrete-filled (rectangular) stainless steel tubular (SRCFSST) specimens were investigated by eccentric compression tests. Test results demonstrated that the embedding of CPS improved the load-carrying capacity, expanded the plastic hinge range and inhibited the development of concrete cracks in the rectangular SRCFSST columns. Before achieving the peak load, the majority of the confining stress was presented in the corner region of the rectangular stainless steel tube. After that, both CPS and rectangular stainless steel tube delivered the confinement. A finite element (FE) model was developed to study the effects of different parameters on the axial load versus bending moment curves and axial compression stability coefficients of the rectangular SRCFSST columns. The carbon steel ratio and material strength were the most affecting parameters. Finally, a revised simplified model for determining the eccentric compression resistances of the rectangular SRCFSST columns were developed. The predictions using the simplified model agreed well with the test results or FE results.

Abstract ：
To reveal the changes in the mechanical properties of high-strength bolted connections with different hole types after corrosion, four groups of high-strength bolted connection specimens with steel plates assembled by highstrength bolts were subjected to neutral salt spray accelerated corrosion tests followed by shear tests. Based on the test results, the influence of corrosion duration on the slip coefficient, bolt pre-tension, initial slip load and ultimate bearing capacity of high-strength bolted connections with different hole types are discussed, followed by the presentation of simplified methods to determine the slip coefficient and bolt pre-tension with corrosion duration taken into account. It is found that one-day acceleration corrosion in the salt spray chamber of this paper can be roughly regarded as one-year exposure in the natural environment of Jiaodong Peninsula of China, especially for the long-term corrosion. Test results show that the corrosion has a more pronounced influence on the slip coefficient of high-strength bolted connections with enlarged bolt holes, while the pre-tension of the high-strength bolt is more sensitive to corrosion when standard hole is used. It is also observed that the initial slip load of high-strength bolted connections are significantly affected by corrosion while the corrosion hardly changes the ultimate bearing capacity regardless of bolt hole type. It is proved that the proposed simplified methods to determine the amplification factor of slip coefficient and bolt pre-tension can be used to evaluate the initial slip load of high-strength bolted connections in corrosive environments conservatively.

Abstract ：
In this study, biaxially eccentric compression experiments were conducted on 26 concrete-filled square stainless steel tubular (CFSSST) columns. The test findings showed a 21.14 % reduction in the eccentric compression resistance when the eccentricity was increased from 0 to 40 mm. When the slenderness ratio increased from 10.39 to 41.56, the eccentric compression resistance was reduced by 21.92 %. When the cubic compression strength of the concrete was increased from 38.6 to 78.8 MPa, the eccentric compression resistance increased by 53.26 %. A corresponding finite element (FE) model was created, and the FE analysis demonstrated that the CFSSST column had higher peak displacement, bending resistance, and ductility than the conventional concrete- filled square steel tubular (CFSST) counterpart. The axial load vs bending moment curves for the CFSSST and CFSST columns were fairly similar. However, increasing the eccentric angle reduced the load capacity of the CFSSST specimen by up to 15.37 %. Previous simplified methods overestimated the carrying capacities of CFSSST specimens. However, the revised model exhibited higher prediction accuracy.

Abstract ：
To investigate the hysteretic behaviour of (carbon) steel-reinforced concrete-filled (rectangular) stainless steel tubular (SRCFSST) specimens, lateral cyclic tests were performed on nine SRCFSST or concrete-filled (rectangular) stainless steel tubular (CFSST) specimens. The tests revealed that the rectangular SRCFSST columns suffered slight concrete damage due to the confinement of the carbon profiled steel (CPS). The use of CPS made the hysteretic loops of the composite columns plumper. The lateral carrying capacity, ductility index, energy dissipation coefficient, cumulative dissipated energy, and flexural stiffness of the composite specimens increased by an average of 25.3 %, 13.4 %, 16.1 %, 71.8 %, and 88.4 %, respectively. A finite element (FE) model of the rectangular SRCFSST specimen was constructed to analyse the influence of the CPS and the parametric effects on its hysteretic performance. The FE parametric analysis reveals that increasing the stainless steel ratio, carbon steel ratio, material strength, or rotation radius significantly increases the bearing capacity of the SRCFSST specimen. Finally, the lateral load versus displacement hysteretic models of the rectangular SRCFSST specimen were refined. © 2025 Elsevier Ltd

Abstract ：
Steel-reinforced concrete filled stainless steel tube (SRCFSST) columns are predicted to offer excellent durability, load bearing capacity, ductility, fire resistance, impact resistance, and seismic performance. Therefore, eccentric compressive tests of 18 circular SRCFSST columns were carried out to investigate the effects of the slenderness ratio, load eccentricity, and embedment of carbon-profiled steel (CPS) on circular SRCFSST columns. The ultimate strength and ultimate deflection of the composite columns were improved significantly after the CPS was embedded. A finite element (FE) model was established and the FE analysis indicated that the CPS was proved to be an effective means of constraining concrete. Based on the FE parametric analysis, it was shown that the stability coefficient decreased with increasing concrete strength, proof strength of stainless steel, and CPS yield strength, but increased with increasing rotation radius-diameter ratio. The greater the concrete strength, the more similar the N similar to M interaction curves of the SRCFSST columns and reinforced concrete columns. The higher the CPS yield strength, stainless-steel ratio, slenderness ratio, carbon steel ratio, or proof strength of stainless steel, the more similar the interaction curves of the SRCFSST columns and profiled steel columns. Finally, the simplified model was refined to forecast the carrying capability of a circular SRCFSST specimen under the eccentric compression.

Abstract ：
Round-ended concrete-filled steel tubular (CFST) columns have numerous benefits, including easy construction, aesthetic appearance, and variable section arrangement. This study experimentally and numerically investigated the flexural behavior of round-ended CFST columns. The six testing results showed that as the aspect ratio increased from 1.38 to 1.86, the flexural resistance and stiffness increased by 82.0% and 159.9%, respectively. Every round-ended CFST specimen had excellent ductility. Concrete can be adequately confined by the roundended steel tube. Mechanistic and parametric analyses were carried out using a finite element model. Mechanistic analysis demonstrated that the round segment of the steel tube can effectively confine the concrete, resulting in a considerable strength gain near the edge of the compression zone. The parametric analyses showed that as the concrete strength increased from 24 to 110 MPa, the flexural resistance increased by average 20.4%; as the steel strength improved from 235 to 700 MPa, the flexural resistance increased by average 155.4%; as the steel ratio enhanced from 0.05 to 0.2, the flexural resistance increased by average 179.7%; and as the aspect ratio increased from 1 to 3, the flexural resistance of the major (minor) axis increased (decreased) by about 59.9% (36.5%). The analysis showed that the flexural stiffness of this composite specimen can be accurately predicted by AISC 360-2016. Finally, a simplified model was proposed for estimating the flexural resistance of the roundended CFST specimens.
