Abstract ：
为探讨预制超高性能混凝土(Ultra-high Performance Concrete,UHPC)叠合承压板基本力学性能,开展了UHPC承压板足尺模型试验、数值分析和优化设计.结果表明,U HPC承压板受力全过程分为弹性阶段、弹塑性阶段和破坏阶段,最终因受压区UHPC被压溃而破坏,其破坏模式和裂缝分布与传统 RC承压板基本相似,但因UHPC具有较高的抗拉/抗压性能,可有效抑制裂缝的扩展,并显著提升结构承载力;经模型试验验证,基于ABAQUS软件提出的有限元建模方法可较好地模拟 UHPC承压板的受力全过程与极限承载力,随着钢筋直径和UHPC抗拉/抗压强度的增大,U H PC承压板极限承载力随之提高,但荷载～位移和钢筋荷载～应变曲线弹性段斜率基本保持不变;在满足结构受力要求的前提下,通过削减叠合承压板数量可进一步减轻自重,优化设计后的UHPC承压板重量较传统RC承压板可降低 26.0％,全寿命周期成本可减小7.2％,使用年限可提高1倍.

Abstract ：
Ultra -high performance concrete (UHPC) is an innovative cement -based composite material characterized by extremely high durability and mechanical properties, which provides a potential possibility of using non -desalted sea -sand as aggregate. However, the long-term steel corrosion behavior in UHPC prepared by simulated sea -sand under different immersion environments remains unclear, which is of great significance for the application of sea -sand UHPC in practical engineering. In this study, the pore structure of sea -sand UHPC matrix was measured using nitrogen adsorption/desorption method. The corrosion behavior of rebar in sea -sand UHPC with different endogenous chloride ion contents soaking in pure water and NaCl solution was characterized by linear polarization resistance (LPR), electrochemical impedance spectroscopy (EIS) and cyclic polarization (CP). The experimental results show that the initial UHPC pore structure is refined by incorporation of sea -sand, and is similar to that of ordinary UHPC at the later hydration. Regardless of the endogenous chloride ion content and immersion environment, the corrosion rate evaluated by corrosion current density (icorr) and polarization resistance (Rp) of reinforcement in UHPC is extremely low. The measurement of EIS shows that UHPC group has higher matrix resistance (Rc) and charge transfer resistance (Rct), while lower electric double layer capacitance (CPEdl) of reinforcement, which indicates that the steel in UHPC made of sea -sand is still in a state of passivation. However, the steel bar in comparison specimen OPC soaking in NaCl solution is in the corrosion stage. Furthermore, sea -sand UHPC possesses of excellent ability of anti -pitting corrosion of reinforcement after 180 days of immersion in NaCl solution.

Abstract ：
超高性能混凝土(Ultra-high performance concrete, UHPC)单轴拉伸(直拉)试验是分析UHPC抗拉性能和直拉本构关系的基础性试验，经过对其试件形状与尺寸的优化，试验成功率已得到了较大提升。但由于试件连接方式和局部加强方式的差异，各机构试验成功率参差不齐。为进一步保证直拉试验成功率，采用试验研究和数值模拟的方法系统分析了常见的四种试件连接方式和三种试件局部加强方式对试验成功率的影响，比选出最优试验方法。结果表明：面内夹持装置具有连接可靠、操作简单的优点，适合推广。但夹具的尺寸加工误差或微变形可能导致其与试件的接触面变窄、加剧夹持引发的试件应力集中，致使主裂纹位于测距范围之外；试件与夹具的接触区域进行柔性加强(粘贴碳纤维布)和刚性加强(粘贴铝片)均能有效解决上述问题，提高试验成功率。此外，采用比选的直拉试验方法，探究了钢纤维长径比和体积率对UHPC直拉损伤本构关系的影响。通过声发射(Acoustic emission, AE)监测探究了UHPC在直拉荷载作用下的损伤演化规律，利用声发射参数(累积计数比)构建损伤因子，得到了考虑钢纤维影响的UHPC直拉损伤本构关系。

Abstract ：
Uniaxial tensile test of ultra-high performance concrete(UHPC)is a basic material test to analyze its tensile properties and tensile constitutive relationship. Through optimization of the shape and size of the specimens,the success rate of the test has been greatly improved. However,due to the difference in the connection device and reinforcement method,the success rate of each institution is uneven. In order to further ensure the success rate of the uniaxial tensile test,the influence of four common connection devices and three reinforcement methods on the success rate of the test were systematically analyzed through experimental research and numerical simulation,and the optimal test scheme was selected. The results showed that the in-plane clamping device has the advantages of reliable connection and simple operation,which is suitable for popularization. However,there is a problem that the size processing error or micro deformation of the clamp leads to the narrowing of the contact surface with the specimen,intensifies the stress concentration caused by clamping,and makes it impossible to control the main crack to be located in the measuring range;both flexible reinforcement (paste carbon fiber reinforced polymer)and rigid reinforcement (paste aluminum sheet) of the contact area between the specimen and the fixture can effectively solve the above problems,increase the success rate. In addition,the influence of the aspect ratio and volume fraction of steel fibers on the damage constitutive relationship of UHPC under uniaxial tension was investigated by using the optimal uniaxial tensile test method. The damage evolution law of UHPC under uniaxial tensile load was explored through acoustic emission (AE)monitoring. The damage factor was constructed using AE parameters (cumulative counts ratio),and the uniaxial tensile damage constitutive relationship of UHPC considering the influence of steel fiber was obtained. © 2024 Cailiao Daobaoshe/ Materials Review.

Abstract ：
The concrete-filled steel tubular (CFST) arch bridges with circular tube ribs usually adopt the sparsely arranged transverse braces, which have a large shear deformation in the out-of-plane instability, it is not suitable to use the existing calculation method based on the assumption that shear deformation is not considered. Taking the lattice columns with sparsely battened plates as the research object, the calculation formula of elastic stability bearing capacity of lattice columns considering the shear deformation is derived. Based on the calculation formula of elastic stability bearing capacity of lattice column and by employing the equivalent beam-column method, the calculation formula of out-of-plane elastic stability bearing capacity considering shear deformation for CFST arch bridge with circular tube ribs is proposed. The parameter analysis on the standard CFST arch bridges with circular tube ribs are carried out by finite element(FE) method, the results are compared with the calculation results according to formulas considering and without considering shear deformations, and formulas recommended by the existing codes and references. The results of research show that in the scope of structure dimensions commonly used in engineering, the results obtained by recommended formulas in existing codes and references are one order of magnitude smaller than those obtained by finite element method, they are not suitable for the calculation of out-of-plane elastic stability bearing capacity of CFST arch bridge with circular tube ribs. The error between FE analysis and proposed calculation formula of out-of-plane elastic stability bearing capacity considering shear deformation for CFST arch bridge is within 15%, which has a large precision improvement and good applicability. © 2024 Editorial Board of Jilin University.

Abstract ：
无伸缩缝桥梁由于取消了伸缩装置,从而可彻底地解决伸缩装置的养护问题,是一种可持续发展的桥梁形式.它的应用以梁桥为主,在拱桥中应用相对较少.该文以云南八丘田桥为例,该桥为上承式拱桥,其拱上桥道结构与两引桥跨直接相连形成连续结构,并延伸至台后的引板(搭板),从而消除了全桥的桥面伸缩缝,使其成为一座无伸缩缝拱桥.该文阐述了无伸缩缝拱桥的主要类型,重点介绍了八丘田桥的设计,并分析了上承式拱的桥面伸缩量、取消伸缩缝对结构受力的影响.

Abstract ：
The macro properties of fiber reinforced concrete is significantly associated with the spatial distribution of fiber. In this paper, the statistics-based algorithms characterizing fiber spatial distribution including orientation probability, spacing distance and wall effect were proposed based on the established the random generation model of cylindrical fibers in an ideal three-dimensional fiber reinforced concrete matrix. The influence of fiber physical parameters on the overall fiber spatial distribution were statistically analyzed. The results show that the fiber orientation probability in ideal fiber reinforced concrete matrix is almost constant. The fiber geometric size plays an important role on the fiber spatial morphological characteristics, where the fiber spacing distance in-creases with the fiber length and diameter, and the wall effect is significantly affected by the fiber length. The heterogeneity of fiber distribution characterized by the higher fiber spacing distance in the edge region is associated with the fiber sparsity mainly influenced by the single fiber volume and total fiber fraction. With the constraints of wall effect and principal stress direction, the boundary region parallel to the principal stress has a higher fiber orientation coefficient, while the region perpendicular to principle stress possesses of the lowest coefficient.
