摘要

摘要: 介绍了框架节点分类的研究现状，并将其应用于钢-混凝土组合节点的分类研究。通过对端板连接钢-混凝土组合节点的试验结果进行分析表明，采用Bjorhovde等人的节点分类方法，不需知道节点的具体构造，但易得到错误的划分结果；运用EC3的划分方法一般能较明确地划分钢-混凝土组合节点的类别；使用Nethercot等人的节点分类方法则通常偏于保守；而采用非线性弯矩-转角曲线的节点分类方法，只要确定曲线的参数，即可将节点明确划分为刚性、半刚性和铰接，从而明确节点的性质。

Abstract: Some connection classification systems presented by scholars were reviewed.The systems were applied in the composite joints in this paper.From endplate composite joint specimens test result conducted by authors, it was found that the classification system by Bjorhovde et al do not require the detail of the joints in calculation but often lead to mistakes, the criteria of classification in EC3 is basically suitable for the application in composite joints and the classification system presented by Nethercot et al is too conservative.Compared with these three methods, the nonlinear moment-rotation curves model is more accurate to categorize a real connection into any of three types: rigid, semi_rigid or flexible, if the calculation parameters are determinated based on the test.
