Abstract ：
高强方钢管超高性能混凝土构件在大跨桥梁、超高层建筑等工程中均有着广泛的应用前景.为研究高强方钢管超高性能混凝土短柱的轴压力学性能,设计制作了 16根方钢管混凝土短柱,并对其开展轴压试验,研究了混凝土抗压强度、钢管屈服强度、截面宽厚比等参数对其轴压性能的影响.通过ABAQUS有限元软件对试件进行非线性有限元分析和参数分析,以明确高强方钢管超高性能混凝土轴压短柱的受力机理.研究结果表明:高强方钢管超高性能混凝土短柱轴压性能良好;提高混凝土抗压强度可显著提升轴压承载力和刚度,且对延性影响不大;提高钢材屈服强度可提升承载力,但对轴压刚度和延性的影响较小;减小截面宽厚比可提升轴压承载力、刚度和延性,并延缓局部屈曲和剪切破坏.最后,将已有试验统计数据和所得试验结果与中国规范GB 50936-2014、欧洲规范EC4(2004)和美国规范AISC 360-22中相关公式的计算结果进行对比,发现GB 50936-2014对高强方钢管超高性能混凝土短柱轴压承载力的预测偏差较大,欧洲规范EC4(2004)的预测不够安全,且无法考虑钢管局部失稳的影响;美国规范AISC 360-22的计算结果与试验结果较为接近,且考虑了钢管局部失稳的影响.

Abstract ：
This study investigates the cyclic behavior of high-strength square concrete-filled steel tube (HS-SCFST) beamcolumns through experimental testing of 9 specimens and complementary finite element analysis. The specimens were subjected to constant axial load and cyclic flexural loading, with test parameters including axial compression ratio, steel yield stress, concrete compressive strength, and width-to-thickness ratio. The finite element models were benchmarked for parametric studies. The results showed the axial compression ratio influenced ultimate strength and envelope curve shape, while increased steel/concrete strength improved strength and energy dissipation capacity. However, higher slenderness and width-to-thickness ratios decreased strength, ductility, and stiffness notably. Evaluation of building codes GB50936, EC4, AISC360-16, and AIJ showed EC4 was most reasonable, GB50936 most conservative as it neglects stress distribution between steel and concrete, and AISC 360-16 conservative as it excludes concrete contribution. The study indicates existing code provisions need improvement for calculating HS-SCFST member strength. Additionally, a simplified calculation model was proposed to determine envelope curves for HS-SCFST beam-columns based on the experimental and FE results. In summary, the study provided data on HS-SCFST cyclic behavior and code evaluations, proposing enhancements for design.

Abstract ：
This paper investigates the axial compressive behavior of an innovative composite wall consisting of stainlessclad bimetallic steel faceplates and ultra-high performance concrete (UHPC) infill. The innovative wall can address three major challenges of traditional steel-concrete composite walls, i.e., rapid degradation of the lateral stiffness, insufficient ductility of the concrete infill, and limited corrosion resistance of steel faceplates. A total of 12 tests were first conducted, considering the effects of normalized faceplate slenderness ratio (7), concrete type, and steel type. Finite element models were then developed and benchmarked for parametric studies. Results from tests and parametric analysis showed that: (1) failure modes of the composite wall were local buckling of steel faceplate and concrete crushing; (2) increasing 7 significantly reduced the axial compressive strength of the composite wall and critical buckling stress of the steel faceplate, but had a negligible effect on the axial stiffness; (3) UHPC greatly improved the compressive strength and axial stiffness of the composite wall, but also resulted in a more brittle behavior. Finally, the applicability of current design provisions (i.e., CECS:546-2018, Eurocode 4, and AISC 360-22) for estimating the axial compressive strength was evaluated, and a new design equation was proposed.

Abstract ：
This paper investigates the axial compressive behavior of assembled composite wall (ACW) which consists of a double steel plate-concrete composite shear wall and two external concrete layers on both sides. 29 ACW specimens and 4 double steel plate-concrete composite shear wall (DSCW) specimens were tested under axial load. ACW demonstrates excellent axial compression performance, with its axial compressive strength and deformation abilities both being superior to DSCW. Test results indicate that: i) the ratio of shear connector spacing-to-plate thickness (s/t) has a significant influence on the axial compressive strength, failure mode and local buckling load of the specimens; ii) the external concrete layers can delay the local buckling of the steel plates and enhance the axial compressive strength of the composite shear wall. The impact of the external concrete layers on the axial compressive behavior of ACW is related to their arrangement form. Finally, three different codes were evaluated, the results show that EC4 and GB/T 51340-2018 calculation results match well with the test results. © 2024 Institution of Structural Engineers

Abstract ：
The double steel plate concrete composite shear wall (DSCW) structure combines the advantages of steel and concrete, offering high strength, stiffness, and durability. The joint formed by the DSCW and reinforced concrete foundation (RC foundation) was often unavoidable in engineering practice. Research related to the mechanical behavior of the DSCW-RC foundation is limited. This paper investigated the shear performance of DSCW-RC joints with lap-spliced steel bars. A total of seven specimens were designed and tested. The influences of steel plate thickness, steel bar arrangement, and stud spacing on the shear behavior of the joints are elucidated. The test results indicate that the predominant failure mode of the specimens occurred in the upper part of the local steel plate, with reinforcement yielding. While steel bar diameter and stud spacing minimally affected the shear strength, they significantly influenced the failure displacement at the joint interface. The failure deformation increased with increasing steel bar diameter and decreased with increasing stud spacing. Moreover, the thickness of the steel plate profoundly impacted structural shear strength and deformation, with both deformation and bearing capacity increasing with plate thickness. In addition, this study explores the force-transferring mechanism of such joints under shear load, offering a crucial reference for subsequent analyses of the composite force mechanism of DSCW - RC foundation joints. © 2024 Institution of Structural Engineers

Abstract ：
This study investigated the flexural performance of corrugated top flange steel-concrete composite beams in the negative moment region by tests and numerical analysis. A total of three static loading tests were conducted, including two specimens with corrugated top flange and one specimen with normal top flange. Test parameters were the type of the top flange and the longitudinal reinforcement ratio. The failure mode, crack pattern, and capacity of the specimens were discussed. The results showed that the failure mode of all three specimens was flexural failure. The capacity and ductility increased using the corrugated top flange, and the improvement in crack resistance by the corrugated top flange was much greater than reinforcement ratio. A calculation method for flexural capacity was proposed according to the tests and analysis. The calculated flexural capacity was in good agreement with the test results with a relative error of less than 10 %. The test results were also used for calibrate numerical models for further parametric study. It was found that the flexural capacity increased with increasing corrugation angle or decreasing the corrugation height, while the effect of corrugation height was higher on the structural performance.

Abstract ：
The flexural behavior of 12 ultra-high-performance concrete (UHPC) encased concrete-filled steel tubular (CFST) beams was experimentally investigated with steel fiber content. The influence of steel fiber content and CFST diameter on the general structural behavior, failure modes, stiffness, and flexural capacity were discussed. The test results showed that the outer UHPC can work in good coordination with the inner CFST, and steel fiber is effective in improving the overall flexural performance of UHPC encased CFST beams. The predictions of flexural stiffness by existing code provisions were compared with the test results. In addition, numerical analysis was conducted to benchmark test results, and to perform an in-depth analysis of the stress development and load distribution between UHPC, steel and core concrete. The applicability of existing equilibrium section method in predicting the flexural strength of UHPC encased CFST beams was then evaluated, and a reduction factor was proposed to calibrate the calculation results. © 2024 Institution of Structural Engineers

Abstract ：
This study experimentally and numerically investigated the behaviors of UHPC-filled high-strength square steel tube stub columns with compact, noncompact and slender sections under combined flexural and axial loads. Eighteen tests were conducted, addressing the gap of limited tests on concrete-filled square steel tubular stub columns with noncompact or slender sections. Additionally, finite element analyses were developed and benchmarked for parametric studies. The results of tests and parametric studies show that (1) steel tube outward buckling and concrete crushing occurred at 1/4–1/2L of the compression zone; (2) the load-axial displacement curves organized into three phases: elastic, elastic-plastic, and recession phase; (3) the compressive strength increased with increasing tube thickness, concrete strength, and steel yield strength. The compressive strength decreased with increasing eccentric ratio and slenderness coefficient. Test and numerical results are utilized to assess the suitability of current design specifications for predicting compressive strength. The evaluation showed that neither GB 50936–2014 nor Eurocode 4 provided reasonable predictions of strength, while AISC 360–16 provided conservative predictions. © 2024

Abstract ：
Concrete filled steel tubes (CFST) can fully utilize the advantages of both steel and concrete to achieve superior ductility and strength. Therefore, an increasing number of CFST members are used as truss chords in bridge construction in earthquake zones. However, due to concrete settlement, concrete shrinkage, and temperature shift during service life, spherical-cap gaps may exist inside CFST chords, which will have an unfavorable influence on the seismic behavior of the web-chord connections. In this study, the hysteretic behavior of steel tubular T-joint with concrete-filled bottom chord with spherical-cap gap is experimentally investigated. A total of 24 T-joint specimens were tested with the CFST chord under the constant tensile load and the steel tubular web subjected to cyclic bending. The main testing parameters included spherical-cap gap ratios, chord to web diameter ratios, and chord diameter to thickness ratios. Based on the test results, the failure modes, hysteretic response, load-carrying capacity, stiffness degradation, ductility and energy dissipation characteristics were investigated and analyzed. The effect of spherical-cap gap on the hysteretic behavior of CFST T-joints was compared and discussed. The outcome of this research is expected to provide reference to the evaluation of seismic safety of CFST truss structures.
