摘要连接的受力性能的研究和计算的简化模型的确立是理解半刚性节点的基础。为此对双
腹板、顶底角钢半刚性节点的试验数据进行分析,绘出试件各组合件关键点的荷载与应变变
化曲线。荷载-应变关系曲线是理解各细部的受力变形特征和试件在加载过程中受力缺陷(如
扭转)的有效手段。通过数据分析,阐述了试件各组合件在静力荷载作用下的受力机理,验
证了节点的计算模型,为半刚性节点进一步研究提供依据。

Abstract :The research of the loading capability of connection and the establishment of
calculational module are the base of understanding semi-rigid joints. Then the paper analyses of
the experimental data of joints of top and seat angle with double web angle and draws load-strain
curves of member subassemblages key points . Load-strain curves are the effective means to
understanding the subassemblage distortion characteristic and imperfection (. torsion ) under
loading .Through the data analyzing , it states the member mechanism under static loading ,
confirms the calculational module of the joints and provides the foundation for the furthermore
research of semi-rigid joints.
Keywords: Joints of Top and Seat Angle with Double Web Angle Moment-Strain curves
