T形钢管混凝土柱-工字钢梁框架顶层边节点抗震性能试验研究OA北大核心CSCDCSTPCD
Shear capacity of joints between concrete-filled square steel tubular special-shaped columns and steel beams
选择T形截面钢管混凝土异形柱-工字钢梁框架顶层边节点为研究对象,按1∶2的缩尺比例设计并制作3个＂弱节点＂模型和1个＂强节点＂模型,通过施加恒定轴压比的竖向荷载和低周往复水平荷载,对节点模型进行加载破坏试验,观察节点模型的受力过程和破坏形态,得到水平荷载-柱端位移滞回曲线和骨架曲线,分析节点荷载特征值、延性、耗能以及刚度退化等。试验结果和分析表明：弱节点试件破坏形态主要为节点核心区在剪压复合应力作用下的剪切破坏,随轴压比增大,试件受剪承载力提高,…查看全部>>
According to the experimental research of the joints between concrete-filled square steel tubular special-shaped columns and steel beams,the factors which influence the failure features of the joints were analyzed.The results indicate that the typical failure mode is shear diagonal compression in the core of the joint.The shear mechanism is the combination of steel truss mechanism,the main compression strut mechanism and the confined compression strut mechan…查看全部>>
