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.
