异形钢管混凝土柱-钢梁节点研究

Research of Connections Between Special-shaped Concrete Filled Steel Tube Column and Steel Beam

介绍了梁柱节点的3种连接形式,并对当前现有节点进行了比较分析,讨论了其在异形钢管混凝土柱结构体系上使用的可能性,指出现有节点有些不适用于异形钢管混凝土柱框架结构体系,能够使用的也不能完全达到预期的效果。对比分析确定穿芯式节点比较符合要求,并简要介绍了异形钢管混凝土柱框架节点的研究现状。最后对该节点后续的研究提出了一些看法和建议。

This paper describes three types of the joint and make a comparative analysis about the current joint,clarify its strengths and weaknesses.As a result,some joints can not be used in it,and some joints used can not achieve desired results,finally we find that straight-node can achieve the requirements,then we make a brief introduction about special shaped concrete filled steel column frame node,at last,some observations and suggestions about the joint in future research are proposed.
