摘要: 对圆钢管相贯节点非刚性能的表达参数进行了分析,在对参数影响效应进行机理性解释的基础上引入计算公式的参数化模型。通过对现有国内外计算公式的总结比较和基于国际钢管节点试验数据库的统计分析,分别从节点抗弯刚度和抗弯极限承载力两方面,提出了具有较高精度和适用性的节点非刚性能计算公式。Abstract: The parameters expressing the non-rigid properties of unstiffened circular hollow-section joints are analysed.Based on the explanation of the mechanism of effects which are controlled by those parameters, parametric models for computation formulae are introduced.It is compared that current parametric equations found from different codes or specifications with test data extracted from international test database of unstiffened tubular joints.By statistical analysis, parametric formulae of joints, both bending rigidity and ultimate bending capacity with most accuracy and applicability, are identified.
