钢结构模块间梁-梁型节点抗拉与抗剪性能研究
Research on Tensile and Shear Behavior of Inter-Module Beam-to-Beam Joint for Modular Steel Buildings
模块化钢结构建筑具有集成化程度高、现场施工时间短、可循环利用等特点。作为结构受力与安装的关键结构,模块间连接节点的构造形式需兼顾施工便利性与传力可靠性。为此,文中提出一种适用于多高层模块化建筑的梁-梁型节点构造。该节点通过盖板与螺栓连接相邻模块梁,对施工空间需求小、操作便捷且传力路径清晰,为模块化钢结构在高层建筑中的高效连接提供了解决方案。文中首先通过试验研究了节点在拉力、剪力作用下的承载性能与破坏模式;其次,通过理论分析分别提出了节点抗拉、抗剪设计承载力的计算方法;最后,对比理论计算结果与试验结果,验证了所提理论计算方法的准确性。研究结果可为该类节点的设计分析与工程应用提供参考。
Modular steel buildings are characterized by high-degree integration, short on-site construction time, and recyclability. As the most critical component in structural load-bearing and installation, inter-module connections must balance construction convenience with reliable force transfer. To address this, this paper proposes a beam-to-beam joint configuration suitable for multi-story and high-rise modular buildings. This joint utilizes cover plates and bolts to connect adjacent module beams, offering minimal construction space requirements, operational convenience, and clear force transfer paths, thereby providing an efficient connection solution for modular steel structures in high-rise applications. First, experimental studies were conducted to investigate the load-bearing behavior and failure modes of the joint under tensile and shear loading. Subsequently, theoretical analysis was employed to propose calculation methods for the tensile and shear design load-bearing capacities of the joint. Finally, the accuracy of the proposed theoretical calculation methods was verified through comparison of theoretical results with experimental data. The findings may provide reference for the design analysis and engineering application of this joint type.
