Abstract ：
To study the influence of transverse spacing and different arrangements of stud connectors on structural mechanical performance, ten local full-scale model specimens were designed and manufactured. Transverse bending and tensile performance tests were conducted at the center of the bridge deck support and the cantilever side. The results indicated that, under interior side curvature, the studs were subjected to compression on the side of the stiffener and tension on the outer side of the web. All studs on the outer side of the web experienced tensile fractures near the stud head. Under cantilever side curvature, the studs were subjected to compression on the outer side of the web. Due to the constraint effect of the stiffeners on the upper flange, the studs on the side of the vertical stiffener were primarily in tension. Under the same transverse arrangement of studs, the bending and tensile bearing capacities under cantilever side curvature were significantly lower than those under interior side curvature. For a given unit length arrangement of studs, when four studs can be accommodated within the flange width, it is advisable to evenly distribute the studs on both sides near the web to prevent detachment. It is recommended to avoid placing studs directly above the stiffeners and webs. When designing the transverse arrangement of studs, it is suggested to use four rows of studs, maintaining a ratio of 0.15 between the transverse spacing and the width of the upper flange of the I-beam.

Abstract ：
Considering the distinct fatigue failure patterns exhibited by concrete-filled steel tubular (CFST) K-joints, this study introduces a novel design featuring internally positioned studs arranged in a circular configuration along the intersecting weld seam, referred to as the CFST KSC-joint. A comprehensive full-scale fatigue test was conducted on the CFST KSC-joint model, with its hot-spot stress distribution and fatigue failure mechanisms compared to those of CFST K-joints without studs (CFST-K) and with array-arranged studs (CFST-KSA). Further, finite element parameter analysis was employed to explore the influence of the circular arrangement and geometric parameters of the internal studs on hot-spot stress. Drawing upon the existing array-arranged stud configurations, an optimized circular arrangement of internal studs for CFST K-joints was proposed. Our findings reveal that the failure modes of CFST KSC-joints mirror those of CFST-K and CFST KSA-joints, involving stages of fatigue crack initiation, propagation, and ultimate failure. The circular arrangement of internal studs outperforms the array arrangement in reducing hot-spot stress and improving fatigue life, thereby enhancing the fatigue performance of the joint. Among the stud size parameters, an increase in stud diameter (phi) significantly improves the effectiveness of reducing hot-spot stress, whereas variations in stud length (h) have a minimal impact. The optimal arrangement of internal studs near the intersecting weld involves placing a single ring of studs along the length of the intersecting weld at positions 0 degrees, 22.5 degrees, 45 degrees, 90 degrees, 135 degrees, and 180 degrees.

Abstract ：
随着社会经济的持续快速发展,已有公路难以满足不断增长的交通量需求,对现有公路的拼宽改造迫在眉睫.选取某实际工程中长联连续T梁桥第一联主桥为研究对象,建立MI-DAS/CIVIL三维杆系有限元模型,分析了混凝土收缩徐变、温度梯度、整体升降温等长期荷载对桥梁水平位移的影响,进一步研究混凝土收缩效应随跨数跨径的变化规律.分析结果表明:4种长期荷载的作用下,纵桥向全拼接使得桥梁在纵、横桥向均会产生变形,最大值出现在桥台或一联的过渡墩位置.其中,混凝土收缩引起的横桥向变形最大,占比达到了 60.95％.推导得到可快速预估混凝土收缩影响程度的经验公式,推导值的误差均在5％以内.

Abstract ：
桥梁结构实时健康监测中存在因为海量数据导致的数据传输和存储成本大的问题,而压缩感知理论的提出为解决该问题提供了全新的思路。压缩感知理论与传统的Nyquist采样定理相比,优势在于它可以实现用少量的采样数据恢复较为准确的原始信号。然而,恢复原始信号是一个病态逆向问题,因此如何求解这个病态逆向问题和提高压缩感知信号重构的精度引起了许多学者的关注。本文融合Karhunen-Loeve (K-L)变换和近似正交三角(QR)分解来优化压缩感知理论中的观测矩阵,增大观测矩阵列向量之间独立性的同时减小观测矩阵与稀疏基之间的相关性,以满足感知矩阵需具备有限等距性质(Restricted Isometry Property,RIP)的要求,从而提高振动响应信号压缩感知重构的精度和效率。以吉安大桥的环境振动试验加速度动力响应信号为研究对象,进行压缩感知信号重构分析。分析结果表明所提的观测矩阵优化方法相比单独使用K-L变换和近似QR分解优化观测矩阵,可得到更高精度的重构响应信号,且具有更简便和高效的优点;压缩感知重构信号不论在时域还是在频域,其精度均高于未优化观测矩阵重构的结果,重构的信号与原始信号吻合良好。

为了解山区公路驾驶员的驾驶行为特性，利用驾驶模拟技术，在山区公路仿真环境下，对驾驶员进行驾驶模拟仿真试验，探讨不同熟练程度驾驶员的视觉行为特性规律及差异性。结果表明：熟练与非熟练驾驶员在注视次数、注视时间、扫视幅度、扫视速度上均具有显著性差异，具有丰富驾驶经验的驾驶员在视觉搜索方面更有技巧，能够快速准确的捕捉大量信息，但需耗费更长的反应时间，也容易采取较为的冒险动作。驾驶经验尚浅的驾驶员在视觉搜索方面显得较为拘谨，感知信息速度慢，获取信息量较少使所需反应时间短，受自身驾驶经验和驾驶水平限制，车辆操控较为谨慎。

Abstract ：
In order to improve the crack load and failure load of the hinge joint junction surface and solve the problem of the transverse force of the voided slab bridge, the mechanical performance of the prefabricated voided slab bridge with transverse post-tensioning (TPT)was studied. The mechanical mechanism of the hinge joint junction surface was analyzed by a local model test. The full-scale model test was adopted to research the overall mechanical performance of the voided slab bridge. Based on the mechanical mechanism of the hinge joint junction surface, the upper and lower limits of TPT were determined, and the design calculation formula of TPT was put forward. Test results show that the normal and tangential bonding strengths of the junction surface with TPT are 1.40-1.45 and 0.50-0.62 MPa, respectively, which are 8.1%-12.5% and 12.4%-38.3% higher than those without TPT, respectively. Moreover, increasing TPT can improve the normal and tangential bonding strengths of the junction surface. The failure mode of the full-scale test model of the voided slab bridge with TPT is the cracking failure of the voided slab, and no hinge joint cracking occurs during the test. The application of TPT can improve the transverse connection among slabs, avoid the loss of the transverse load transmitting ability due to the hinge joint junction surface damage and the failure of the structure, and increase the ultimate load of the voided slab bridge. The proposed formula for TPT design can effectively calculate the design value of TPT of the voided slab bridge. © 2022 Chang'an University. All rights reserved.
