Abstract ：
基于结构抗震韧性设计理念，提出一种可更换部件的钢管混凝土柱-软钢板组合箱形截面高墩，以改善高墩桥梁的抗震性能。为明确新型组合高墩的正截面承载力，开展了轴心和偏心受压试验，获得其轴向荷载-位移曲线、轴向荷载-应变曲线和破坏模式。以验证后的有限元模型为基础进行参数分析，探讨荷载偏心率、高墩长细比、软钢板厚度对新型组合高墩受压承载力的影响。研究结果表明：新型组合高墩在轴心和偏心受压下均产生了明显的面内整体弯曲变形，破坏模式均为整体弹塑性失稳破坏。偏心受压试件的承载力随偏心率或长细比的增大呈明显下降趋势，且两者的影响近似相互独立，当偏心率由0增至0.54时，承载力最大降低了约49%；当长细比由4增至79时，承载力最大降低了约38%。软钢板厚度由1 mm增加至10 mm，轴压承载力最大仅提高约9.5%，偏压承载力最大可提高约25%。将新型组合高墩简化为平腹杆格构柱，考虑软钢板对柱肢和钢系梁的约束作用，建立了新型组合高墩轴压承载力的计算公式。采用稳定系数和偏心率折减系数相乘得到承载力总折减系数，得到偏压承载力计算公式。该文建立的实用计算公式的计算结果与试验结果和有限元计算结果吻合良好，可用于新型组合高墩的正截面受压承载力计算。

Abstract ：
With the convenient and fast requirements for construction in bridge engineering, prefabricated assembly technology is widely applied in engineering construction. Typically, prefabricated bridge decks are connected through cast-in-place wet joints. Wet joints, as the primary load-bearing parts of bridge decks, undergo complex stress and are prone to cracking and damage. Particularly in the negative bending moment region of bridges, the influence of tensile stress on wet joints is more severe, thus enhancing the mechanical performance and crack resistance of joints becomes crucial. This paper investigates the mechanical behavior of prefabricated reinforced concrete bridge deck panels with variable cross-sections under negative bending moments, focusing on the performance of Ultra High-Performance Concrete (UHPC) wet joints. Full-scale experimental tests were conducted on a 176 m steel truss composite continuous rigid bridge, employing C50 concrete panels with UHPC wet joints. Results show three distinct stages: elastic, crack initiation and propagation, and failure. The maximum failure load reached 822 kN, with a maximum displacement of 21.64 mm. Concrete strains indicate compressive stress near the wet joint and tensile stress near the loading positions. Cracks primarily develop at the wet joint interface and propagate under increasing load, ultimately leading to flexural-shear failure near the variable cross-section of the wet joint. Numerical simulations using ABAQUS/CAE (2020) corroborate experimental findings, closely matching load-displacement curves and identifying damage locations. The study demonstrates that UHPC wet joints significantly enhance crack resistance, meeting design requirements for improved mechanical performance in bridge structures subjected to negative bending moments.

Abstract ：
抗侧刚度是高墩设计中需要关注的构件基本性能之一.通过4个试件的低周往复水平荷载试验,初步研究了轴压比和软钢板相对高厚比对新型可更换部件的矩形钢管混凝土柱-软钢板组合箱形截面高墩抗侧刚度的影响.试验结果表明:在弹性阶段,新型组合高墩试件具有较大的初始抗侧刚度,可满足高墩对墩顶位移量的控制要求;软钢板发生弹塑性屈曲后,试件的抗侧刚度下降32％～53％.利用试验结果对新型组合高墩有限元模型进行验证,以验证后的有限元模型为基础进行参数拓展分析,探讨影响新型组合高墩抗侧刚度的关键因素.参数分析结果表明:轴压比、软钢板相对高厚比及其屈服强度对高墩的初始弹性抗侧刚度几乎没有影响;软钢板发生弹塑性屈曲后的高墩抗侧刚度与软钢板相对高厚比密切相关,当软钢板相对高厚比由200降至100时,屈曲抗侧刚度和最小抗侧刚度分别增加37％和48％.将新型组合高墩简化为由软钢板连接的多肢钢管混凝土柱,分别推导建立了适用于新型组合高墩初始弹性抗侧刚度和屈曲抗侧刚度的实用计算公式,理论计算结果与试验结果和有限元计算结果吻合良好;当软钢板属于中厚板或厚板时,后者计算公式可用于估算大震后新型组合高墩的抗侧刚度.

Abstract ：
为探索牛腿式接缝分段预制拼装预应力混凝土盖梁的静力性能，本文开展了静载试验及有限元模型参数分析，探讨各个影响因素对其受力性能的影响。采用粘性接触单元模拟了牛腿接缝界面的相互作用。研究结果表明：分段预制拼装与整体预应力混凝土盖梁模型相比，开裂荷载和破坏形态基本相同，然而极限承载力和极限变形能力均有明显下降；牛腿接缝界面是分段预制拼装预应力混凝土盖梁的薄弱环节，破坏时临近接缝界面的受拉区混凝土完全分离；此外，牛腿接缝位置设置应综合考虑减轻盖梁的最大吊重与极限承载力之间的冲突；增加预应力筋数量或增大盖梁截面高度，均是提高牛腿式接缝分段预制拼装预应力混凝土盖梁极限承载力的有效措施。

Abstract ：
The load test and finite element model parameter analysis are conducted to explore the static behavior of a segmental precast assembled prestressed concrete cap beam with a corbel joint structure, and the influence of various factors on its mechanical properties is discussed. Interaction at the corbel joint interface is simulated by using viscous contact units. Results show that although the cracking load and failure mode of the segmental precast assembly are basically the same as those of the integral precast PC cap beam model, the ultimate bearing capacity and ultimate deformation capacity of the segmental precast assembly have reduced significantly. The corbel joint interface is a weak link in the segmental precast assembled concrete cap beam. The concrete in the tensile zone near the joint interface is completely separated when damaged. In addition, the setting of the corbel joint position should be considered carefully to reduce the conflict between the maximum lifting weight and the ultimate bearing capacity of the cap beam. Increasing the number of prestressed tendons or the section height of the cap beam is an effective measure to improve the ultimate bearing capacity of segmental precast assembled concrete cap beams with corbel joints. © 2023 Editorial Board of Journal of Harbin Engineering.

Abstract ：
针对中墩独柱支承弯梁桥的抗倾覆问题，以2015年粤赣高速公路城南倾覆垮塌的互通立交匝道桥为背景，提出增加内侧腹板厚度和非对称护栏设置的抗倾覆构造措施，并通过建立桥梁的空间分析模型，采用规范的重载车辆对该措施抗倾覆效果进行分析。结果表明：（1）增加内侧腹板厚度对于提高弯梁桥抗倾覆稳定性具有显著的效果，当内侧腹板厚度增加0.2 m和0.4 m时，抗倾覆稳定系数可分别提高20%～25%和39%～48%，且曲率半径小于300 m时影响更显著；（2）非对称护栏布置对于提高弯梁桥抗倾覆稳定性具有显著的效果，各曲率半径弯梁桥较基准模型抗倾覆稳定系数增加了38%～56%，曲率半径<300 m时半径越小则效果越明显，>300 m后增加效果受曲率变化的影响则很小。

Abstract ：
We constructed the evaluation scale of the professional competence of talents in AI (AI) painting using the Delphi method. The result provided a scientific and effective assessment tool to measure and evaluate the level of professional competence of the talents in AI painting. Through literature analysis and in-depth interviews, the structure and connotation of the indicators of professional competence for cultivating artistic talents were constructed. The Delphi method was adopted by 16 experts and scholars. The results were analyzed based on the scale data to extract factors using exploratory factor analysis and principal component methods. A standard system of professional competence was constructed for artistic talents. The professional competence evaluation scale for AI painting talents presented professional knowledge, skills, and attitudes in which there were four, four, and three dimensions, respectively with 31 tertiary indicators. The evaluation scale of the professional competence of talents in AI painting was used in the efficiency and reliable method to provide a basis for research in the evaluation of talents. © 2023 IEEE.
