钢结构模块间梁-梁型节点抗拉与抗剪性能研究OA

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.
