钢管混凝土柱、型钢混凝土柱、钢柱与钢筋混凝土（RC）梁连接节点研究现状综述

钢-混凝土组合结构兼有钢筋混凝土结构及钢结构的共同优点，具有承载力高、刚度大、延性和抗震性能好及节约材料等突出优点，符合土木工程结构的发展方向。处于复杂受力状态下的梁-柱节点区域是建筑结构整体中需要特别关注的部位，既是整体结构安全性和可靠性的重要基础，又是建筑结构抗震设计的薄弱环节，因此节点部位的设计至关重要。在综合介绍钢筋混凝土（RC）梁与钢管混凝土柱、型钢混凝土柱及钢柱的连接节点结构研究背景的基础上，分析了上述节点连接的构造形式及受力性能等方面的研究现状 ...

钢管混凝土叠合柱-H形钢梁外套筒式连接节点抗震性能试验与有限元研究

以钢管混凝土叠合柱为研究对象，设计了一种高强对穿螺栓连接的外套筒式梁柱节点。为了研究该新型节点的抗震性能和破坏机理，进行了3个缩尺比为1：2的节点拟静力试验。观察节点损伤过程及破坏模式，分析梁端荷载-位移滞回曲线、骨架曲线、节点延性及耗能能力，采用ABAQUS软件建立有限元模型，研究套筒宽厚比和加强肋板厚度对节点抗震性能影响。试验及有限元研究结果表明：节点滞回曲线饱满，延性系数介于3.13~4.19之间，等效粘滞阻力系数介于0.211~0.296之间，节点域的变形和耗能能力较强；随着套筒厚度增加 ...
