In modular steel buildings, the corner bracket type inter‐module connection is a commonly used way of connecting adjacent modules together. However, the detailed working mechanisms of this connection are still not well known. In this study, the mechanical properties of two corner bracket type inter‐module connections were identified based on reported tests and refined finite element simulations. A simplified multi‐spring model of the corner bracket type inter‐module connections was proposed and was then incorporated into the two‐dimensional analysis of a framed modular building and a braced modular building to investigate the effect of connection properties on lateral sway performance of modular structures. Results indicated that the corner bracket type inter‐module connection had a lower tensile stiffness and resistance than compressive ones. Tensile and bending resistances of the connection were correlated with each other and were determined by the out‐of‐plane prying deformation of bracket endplates. The inter‐module connection possessed the extrusion‐resisting and separation‐permitting behavior between assembled brackets. The lateral sway performance of the pure framed modular building was closely related to the vertical shear stiffness of inter‐module connections. However, in the braced modular building, the tension and horizontal shear stiffnesses of inter‐module connections were the critical aspects.

角支架式模块间连接的工作机制评估和简化模型

在模块化钢结构建筑中，角支架式模块间连接是将相邻模块连接在一起的常用方法。但是，这种连接的详细工作机制仍不为人所知。在这项研究中，基于报告的测试和改进的有限元模拟，确定了两个角托架型模块间连接的机械性能。提出了角支架式模块间连接的简化多弹簧模型，然后将其纳入框架式模块化建筑和支撑式模块化建筑的二维分析中，以研究连接特性对模块化侧向摇摆性能的影响结构。结果表明，角支架式模块间连接的抗拉刚度和抗力均低于压缩连接。连接的抗拉强度和抗弯强度相互关联，并由支架端板的平面外撬动变形确定。模块间的连接在已装配的支架之间具有抗挤压和允许分离的性能。纯框架组合建筑的侧向摇摆性能与模块间连接的垂直抗剪刚度密切相关。但是，在支撑式模块化建筑中，模块间连接的拉力和水平剪切刚度是至关重要的方面。纯框架组合建筑的侧向摇摆性能与模块间连接的垂直抗剪刚度密切相关。但是，在支撑式模块化建筑中，模块间连接的拉力和水平剪切刚度是至关重要的方面。纯框架组合建筑的侧向摇摆性能与模块间连接的垂直抗剪刚度密切相关。但是，在支撑式模块化建筑中，模块间连接的拉力和水平剪切刚度是至关重要的方面。
