摘要
研究连接的受力性能并确定计算模型是研究半刚性节点的基础。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 -应变关系曲线。荷载 -应变关系曲线是分析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 ,为进一步研究半刚性节点提供依据。
The research on the loading capability of connection and the establishment of calculational model are the base of understanding semi-rigid joints. Then the experimental data of joints of top and seat angle with double web angle are analyzed and load-strain curves of member subassemblages key points are drawn. Load-strain curves are the effective means to analyze the subassemblage distortion characteristic and imperfection (e.g. torsion ) under loading .Through the data analyzing , the member mechanism under static loading is expounded, and the calculational model of the joints is verified,which provides a foundation for further research on semi-rigid joints.
