【摘要】 文章以某办公大楼的中间层边节点为研究对象，以梁高和连接板厚度为参数建立6个数值模型，并进行拟静力模拟分析，研究模型的应力云图，滞回曲线、骨架曲线、受力特性及破坏规律，研究后发现，增加连接板厚度可以有效提高节点承载力，合理增加柱高可以有效提高节点承载力。二者都在不同程度上提高节点的滞回性能和延性。此类节点形式构造简单，易施工，传力明确可靠，可大力推广使用。更多还原

【Abstract】 This paper takes the middle-floor edge joint of an office building as the research object, establishes six numerical models with beam height and connecting plate thickness as parameters, and carries out quasi-static simulation analysis to study the stress cloud diagram, hysteretic curve, skeleton curve, stress characteristics and failure law of the model.Through the study, it is found that increasing the thickness of the connecting plate can effectively improve the bearing capacity of the joint, and reasonably increasing the height of the column can effectively improve the bearing capacity of the joint. Both of them improve the hysteretic performance and ductility of joints to some extent. This kind of joint has the advantages of simple structure, easy construction, clear and reliable force transmission, and can be widely used.更多还原
