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 ：
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 ：
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∼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. © 2024 Elsevier Ltd

Abstract ：
Axial compression tests of 17 CFRP-PE-stainless steel-reinforced concrete （CPSSRC） short columns and 8 counterparts were carried out to investigate the influences of the stainless steel type，hoop spacing，CFRP thickness，and PE thickness on the failure mode，load versus strain curve，ultimate strain，ultimate strength and ductility of the CPSSRC short column. The experimental results showed that the PE cushion between CFRP and concrete improved the ductility of the CPSSRC column and reduced its ultimate strength. Increasing the CFRP thickness improved the ultimate strength and ultimate strain of the CPSSRC short column，but increased the brittleness. Reducing hoop spacing or increasing steel strength improved the ultimate strength，peak strain，and ductility of the column. A finite element（FE）model was established. The FE analysis showed that increasing the thickness-to-diameter ratio of the PE cushion significantly improved the deformation capacity and ductility of the CPSSRC short column and reduced the effect of CFRP on its ultimate strength. Increasing the hoop ratio，stainless steel strength，CFRP tensile strength，and CFRP thickness improved the ultimate strain and ultimate strength of the CPSSRC short column. Increasing the concrete strength improved the ultimate strength of the CPSSRC short column but reduced its ultimate strain. Finally，a ductile design method，ultimate strength model，and ultimate strain model for the CPSSRC short column were proposed. © 2024 Hunan University. All rights reserved.

Abstract ：
This paper presents a novel high-strength U-shaped bolt (HUB) shear connector, which can enhance the integrity, disassembly ease, construction quality, and efficiency of prefabricated steel-concrete composite beams. Seventeen push-out tests were conducted to investigate the effect of the bolt diameter, reserved aperture ratio of concrete slab, bolt width-diameter ratio, bolt length-diameter ratio, and concrete slab thickness on the shear performance of the HUB shear connector. Specimens with a short length-diameter ratio (h/d <= 3) exhibit damage characterized by bolt pull-out and bolt bending, while those with a long length-diameter ratio (h/d >= 4) experienced bolt shear damage. Subsequently, a finite element model was developed for the push-out tests, enabling a comprehensive study of the shear transfer mechanism, failure mechanism, and stress distribution of the HUB shear connector. Finally, the shear resistance models from different codes were verified. The total slip and simplified load-slip models were proposed.

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.

Abstract ：
In this paper，a finite element （FE） model was used to study the pure bending behaviors of the circular steel reinforced concrete-filled stainless steel tubular（SRCFSST）members. The FE calculation results were in a good agreement with the test results. The flexural resistance of the typical circular SRCFSST member was 111.33% higher than that of the concrete-filled stainless steel tubular（CFSST）counterpart. The bending moment taken by the concrete of the typical circular SRCFSST member was also 23.31% higher than that of the CFSST counterpart. Owing to the increasing confinement on the concrete in the compression zone formed by the steel tube and the flange of the profiled steel，the concrete strength in the compression zone was increased by about 20%. The flexural stiffness and resistance of the circular SRCFSST specimen increased with the concrete strength，stainless steel ratio，profiled steel ratio，and gyration radius ratio. The flexural resistance of the circular SRCFSST specimen increased with the yield strength of the stainless steel or the profiled steel. Simplified models for predicting the flexural stiffness and flexural resistance of the circular SRCFSST member were finally proposed. © 2024 Tongji University. All rights reserved.
