钢管混凝土柱、型钢混凝土柱、钢柱与钢筋混凝土梁连接节点研究现状综述
钢-混凝土组合结构兼具钢筋混凝土结构与钢结构的共同优点,具有承载力高、刚度大、延性和抗震性能好及节约材料等优点,符合土木工程的发展方向。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中的薄弱环节,因此节点部位的设计至关重要。在综合介绍钢管混凝土柱、型钢混凝土柱及钢柱与钢筋混凝土梁的连接节点研究背景的基础上,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,指出了该类节点连接方式及受力性能方面有待进一步解决的问题 ...

以采用外环板连接节点的带钢筋混凝土楼板三层三跨圆钢管混凝土柱-钢梁平面框架为研究对象,从节点损伤角度对该类平面框架的火灾下破坏机理展开研究。建立了足尺的三层三跨钢管混凝土平面框架耐火极限精细化有限元模型,并用相关试验数据验证了建模方法的正确性;基于底层受火危害大于高层受火、边柱受火危害大于中柱受火原则,确定了12种典型火灾工况,深入分析了不同火灾工况下钢管混凝土平面框架的破坏形式、温度、变形发展和内力变化,研究发现不同火灾工况下三层三跨钢管混凝土平面框架的破坏形式可归纳为与节点损伤相关的边柱节点 ...
