This article systematically studies the shear characteristics and structural mechanical response characteristics of composite beam joints. The results indicate that the shear stiffness of the connector is between 1000 N/mm and 2500 N/mm, with high stiffness performance. Meanwhile, as the stiffness increases, the frequency of the structure shows a significant increasing trend, indicating that high stiffness helps to improve the stability of the structure. In the trend chart of shear characteristics and performance of connectors over time, the shear characteristics of connectors significantly increased between 2018 and 2023, with an average shear strength increasing from 1500 N to 2100 N, an increase of 40%. By studying the static and dynamic response characteristics, as well as the bearing capacity, stability, and fatigue performance of composite beams. The results indicate that the response characteristics of the new connector are significantly better than those of traditional connectors. Based on the research results, this article proposes strategies and suggestions for optimizing connector design and improving overall structural performance, providing important theoretical support and practical guidance for practical engineering applications. This study not only enriches the theoretical system of composite beams, but also has important significance in promoting technological progress in related fields.

“…Various factors contributing to potential damage were investigated, including fatigue damage (Li 2015) and temperature and humidity (Hussein et al, 2017). Scholars have sought to address this issue by enhancing design aspects, encompassing innovations in hinge joint structures (Alampalli 1998), transverse pre-stressing methods (Porter et al, 2012), and the utilization of ultra-high-performance concrete (Hussein et al, 2019; Huang et al, 2019; Jiang et al, 2020; Semendary 2018), among others.…”

The assembled beam bridge is a widespread construction, with transverse connections uniting precast beams to jointly support loads. These connections, while crucial, are the most vulnerable elements in such structures. Therefore, the development of an effective index for continuous condition assessment remains the cornerstone of structural health monitoring. The Displacement Spectrum Similarity Measure index, as per ideal conditions in numerical simulations, has shown insensitivity to short-term vehicle loads and sensitivity to transverse connection stiffness. This study extends its scope to address potential real-world interference factors, including measurement errors and deck pavement damage. Specifically, we introduce Gaussian white noise to simulate measurement errors and incorporate additional vehicle loads to emulate the impact of pavement damage. Numerical simulations confirm the robustness of the index against these challenges. Additionally, a real-time index extraction scheme is proposed and implemented on an operational bridge. The results reveal a close alignment between the transverse connection condition assessed by the index and the findings obtained through on-site surveys, thereby substantiating the viability and effectiveness of the index for real-world engineering contexts.

“…Correspondingly, the design solution includes new hinge joint structures [6], transverse prestressing [15], the increase of pavement layer thickness, and the recent use of UHPC material [16]. The application of UHPC to hinge joints seems to be a state-of-the-art solution [17], but it's still in the early stage of promotion and the improvement of the long-term performance of hinge joints has not been fully and widely verified in the industrial community.…”
