Abstract ：
矮塔斜拉桥通常采用对称悬臂法施工,客观条件可能导致该方法无法采用,需要研究非对称悬臂施工的可行性.文章针对双塔双索面预应力混凝土矮塔斜拉桥开展实桥监测,建立有限元模型,分析合理成桥状态和合理施工状态.考虑背景工程无法采用对称悬臂法的实际情况,基于合理施工状态提出边跨现浇段非对称悬臂施工的2种方案,对比采用2种方案完成边跨现浇段施工后对合理施工状态下主梁的挠度、应力及斜拉索索力的影响.结果表明:采用应力平衡法计算成桥恒载弯矩可行域,并以此为约束条件利用基于影响矩阵法原理的未知荷载系数法可计算合理成桥索力;利用考虑施工阶段的未知荷载系数法计算合理初张拉索力及二次张拉索力,可得到合理施工状态;与方案1相比,采用方案2的主梁最大挠度更小且分布更合理,边跨无索区主梁上缘拉应力更小,斜拉索索力分布更均匀;方案2对矮塔斜拉桥的合理施工状态影响较小,最终可达到合理成桥状态.

Abstract ：
This paper investigates the mechanical performance of ultra-high-performance concrete (UHPC) beam-to-beam joints in steel–concrete composite bridges, proposing an alternative to conventional reinforced concrete (RC) joints in continuous beams. The authors employed UHPC with steel end-plates and studs to connect the UHPC crossbeam with the steel beams and RC slab. These connections provides advantages like eliminating the need for on-site welding, simplifying construction, and handling potential tolerance issues. The research includes full-scale experimental tests, a benchmark test on an RC joint, validation of finite element models, parametric analyses, and the development of analytical models to predict the joint's moment–rotation curve, initial stiffness, and ultimate bending capacity. Full-scale experiments revealed that the maximum longitudinal concrete stress in UHPC continuity joints occurs at the interface between the composite steel–concrete beam and the UHPC cross-beams, resulting in crack widths substantially below code limits. The parametric analyses identified critical factors affecting UHPC joint performance, such as concrete strength, steel yield strength, and horizontal stud dimensions. Additionally, the study validated existing formulations for predicting the capacity and stiffness of the joints against the results from the finite element (FE) parametric analyses. © 2024 The Author(s)

Abstract ：
This study presents the structural design and lifecycle analysis of an orthotropic steel deck (OSD) bascule bridge in Viareggio (Italy), considering various operational states and constraints. The analysis varied the bridge's opening angle in 15-degree increments from 0 to 90 degrees, using two steel grades, S355 and S450, by comparing hydraulic or electro-mechanically driven activation mechanisms. The findings reveal that as the static model transitions from pinned-pinned to cantilevered when the bridge is opened, the structural demand for bending moment and shear force increases, with a maximum of nearly 15°–30°. At the same time, axial forces shift from tensile to compressive. Structural design has been carried out using higher grade steel (S450), which has led to a 17.17% mass reduction, cost savings of 3.4%, and a notable decrease in CO2 emissions by 16%. This proves that despite using higher-grade steel characterized by more significant CO2 emissions, the mass reduction associated with the refined design leads to an overall lower environmental footprint. This fact underscores the importance of selecting proper steel grades for steel to achieve an optimal trade-off between CO2 emissions and mass reduction. © 2024 The Author(s)

Abstract ：
The steel slag and ground granulated blast furnace slag with high fineness exhibit synergistic effects on hydration progress and can be introduced into concrete in high volume. In this paper, the simulated pore solution (SPS) of ternary cement incorporating ultrafine steel slag (US) and ultrafine ground granulated blast furnace slag (UG) was prepared to examine the passivation behavior of the HRB400 reinforcing steel under SPS. It is found that the rapid growth of passive films occurs primarily within the initial 2–3 days after immersion in the SPS, while the compaction of passive films takes place mainly at the later stages. The open circuit potential and charge transfer resistance of the passive films initially increase and then decrease with the continuous rise in the US content. The Fe2O3 constitutes a significant portion of the passive films above the steels treated with the SPS irrespective of US dosages, whereas the content of FeO is highly influenced by US dosages. The UG-US-C pore solution could enhance the passivation behavior because of lower Ca2+ and higher Na+. In case of UG/US ratio at 2:3, the passive film exhibits the greatest thickness at 7.5 nm and meanwhile with the highest compaction and the least roughness. © 2024 Elsevier Ltd

Abstract ：
The weak long-term photocatalytic performance of photocatalytic cementitious materials under real-life service conditions has always been one of the main factors restricting their large-scale application. A novel stable three-dimensional structure of S-g-C3N4/MgAl-LDH was constructed by composing S-g-C3N4 with MgAl-LDH, aiming to improve its compatibility with cement mortar to achieve ideal long-term photocatalytic performance under natural exposure. Taking S-g-C3N4 as reference, the possible contributions of MgAl-LDH on improving the mechanical strength and long-term photocatalytic performance of mortar was analyzed by XRD, TG/DTG, SEM-EDX and isothermal calorimetry. The result shows that since the high specific surface area and refinement of MgAl-LDH, the dense surface morphology and fewer surface defects jointly promote the improvement of strength. When the content of S-g-C3N4/MgAl-LDH is 6 %, the 28d compressive strength of composite mortar is excellent, which is 28.7 % higher than the pure cement mortar. More importantly, under the stimulation of the calcium-rich layer on the surface of S-g-C3N4/MgAl-LDH, the accumulation of a large amount of gelling hydration products is beneficial to the stable long-term photocatalytic performance of S-g-C3N4/MgAl-LDH doped mortar. After 180 days of natural exposure, the NOx removal rate of the CMSL-8 % sample can still remain at 68.3 % of the original value (328 μmol·m−2·h−1). This research provides a new theoretical basis for photocatalytic cementitious materials to achieve ideal long-term photocatalytic performance. © 2024 Elsevier Ltd

Abstract ：
The effectiveness of the use of fibers in Ultra-High Performance Fiber Reinforced Concrete (UHPFRC) can be limited by their random orientation in the cementitious matrix. Oriented steel fibers, on the other hand, show significant promise in enhancing the tensile and flexural properties of UHPFRC specimens when the principal tensile stresses predominantly align in a single direction. Despite various proposed methods for orienting steel fibers in UHPFRC, their comparative impact on mechanical properties remained unclear. To bridge this gap, three different strategies were examined in this study, namely: i) chute with vibration table, ii) L-shaped device, and iii) electromagnetic field with vibration table, aiming at controlling the steel fibers orientation in UHPFRC specimens. Uniaxial tensile, four-point flexural, and compressive tests were conducted to examine the influence of different orientation methods on mechanical properties. The experimental findings revealed that compared to randomly oriented fibers, oriented steel fiber UHPFRC had superior tensile, flexural, and compressive strength. Additionally, fiber orientation led to improved consistency of the UHPFRC properties as well as thinner, more densely distributed cracks, regular fracture surfaces, and lower elastic modulus and Poisson's ratio. Electromagnetic field orientation proved to be the most effective orientation method, L-shaped device method the least effective due to heightened fluidity demands in the mixture, and the chute with vibration method ranked in between. This research represents a thorough investigation into the comparative efficacy of different methods for orienting steel fibers in UHPFRC, shedding new light on the optimal approach to enhance mechanical properties. © 2024 Elsevier Ltd

Abstract ：
This paper presents a comprehensive investigation on the positive potential of steel slag (SS) to mitigate the autogenous shrinkage of alkali-activated slag (AAS) while maintaining a reasonably high strength. Changes of the physicochemical properties of AAS with the addition of SS were examined in terms of hydration heat, autogenous shrinkage, chemical shrinkage, internal relative humidity (RH) and mechanical behaviors. The microstructure of AAS-SS systems was characterized using X-ray diffraction, thermogravimetric analysis and nitrogen adsorption techniques. The shrinkage mechanism and quantification approach of the AAS-SS systems were discussed, in addition to a sustainability assessment. The results indicate that the 7-day autogenous shrinkage of AAS paste was decreased by 16 %, 35 % and 42 % when SS was incorporated by 15 %, 30 % and 45 % respectively, owing to the obviously slower hydration and higher internal RH at the early age. Meanwhile, the inclusion of SS substantially mitigates the chemical shrinkage and reduces the pores below 50 nm, thereby significantly decreasing the capillary pressure associated with smaller water-filled pore sizes. Substitutions of blast furnace slag by up to 45 % SS enable to reduce CO2 emissions by 18.4 kg/m3 and decrease autogenous shrinkage by 42 % without obvious compromise in the loss of elastic modulus and compressive strength. © 2024 Elsevier Ltd

Abstract ：
Fatigue represents a critical condition for infrastructure subjected to repeated cyclic loads, such as steel railway bridges. The literature offers several methods to estimate fatigue life, consisting of three main phases: cycle counting, fatigue damage criterion, and damage accumulation criterion. Applying S–N curves might not be conservative in the case of railway bridges subjected to traffic because the stress-time history is complex and cannot be reduced to a sinusoidal history. Additionally, the presence of a multiaxial stress state must be considered. Therefore, this work compares eight multiaxial fatigue damage criteria for evaluating fatigue life in a scenario between high and low-cycle fatigue. Specifically, the authors considered four low-cycle fatigue criteria, namely Smith–Watson–Topper (SWT), Kandil, Brown and Miller (KBM), Glinka, Fatemi and Socie (FS), and four high-cycle fatigue criteria, Crossland, Basquin and the methods recommended by Eurocode 3 and British Standard. The rainflow counting method in ASTM E1049-85 (2011) and Miner's rule for damage accumulation were used. The Polcevera railway steel bridge was selected as a case study. A 3D numerical model was developed for this purpose using Midas Civil software, taking into account the material non-linearity of the bridge's elements. Once the area with the highest stress concentration was identified, a detailed analysis was conducted to estimate the stress and strain time histories induced by train traffic. A sensitivity analysis was conducted after critically comparing the eight methods for predicting fatigue life to assess the impact of traffic parameters, train velocity, axle load, and convoy length on fatigue life. It has been found that the criteria considering axial stress tend to overestimate the number of fatigue cycles to failure compared to the criteria, including the effect of shear stress components. © 2024 The Authors

Abstract ：
With the global construction industry in full swing and the desperate quest to reduce energy consumption and greenhouse gas emissions, there is a growing demand for new technologies to manufacture lightweight concrete structures. This work focuses on foam concrete (FC) and presents the initial results of current experimental campaigns. The purpose of this paper is to investigate the relationship between the flow, mechanical strength, and elastic modulus of the samples and the different dry densities, and the fine aggregate sizes. All samples were cured in water to maintain a constant temperature and humidity environment. The target density of the specimens ranged from 1350 to 1600 kg/m3 with two grades of fine aggregate size. The findings indicate that while the increase in dry density reduces the flow of the foamed concrete specimens, the increase in fine aggregate diameter greatly improves the flowability of the foamed concrete when compared to the control group. Furthermore, the mechanical strength of foamed concrete was enhanced by smaller fine sand gradation because of the presence of more refined pore structure and improved bubble stability. In particular, the foamed concrete specimen with finer sand particle size had a maximum compressive strength value of around 45 MPa and an elastic modulus of about 18 GPa at a dry density of about 1600 kg/m3. © 2024 IEEE.
