Abstract

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.

装配式复合梁接头的抗剪性能和结构力学响应分析

本文系统研究了复合梁连接件的剪切特性和结构力学响应特性。结果表明，接头的剪切刚度在 1000 N/mm 至 2500 N/mm 之间，具有较高的刚度性能。同时，随着刚度的增大，结构的频率呈明显上升趋势，说明高刚度有助于提高结构的稳定性。在连接件的剪切特性和性能随时间变化趋势图中，2018 年至 2023 年，连接件的剪切特性明显提高，平均剪切强度从 1500 N 提高到 2100 N，提高了 40%。通过研究复合梁的静态和动态响应特性，以及承载能力、稳定性和疲劳性能。结果表明，新型连接器的响应特性明显优于传统连接器。基于研究成果，本文提出了优化连接器设计、提高整体结构性能的策略和建议，为实际工程应用提供了重要的理论支持和实践指导。该研究不仅丰富了复合梁的理论体系，而且对推动相关领域的技术进步具有重要意义。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
