摘要
提出4种新型钢管混凝土柱-钢梁连接节点。通过对节点刚度、开裂程度、受力性能、经济性、施工质量等方面的对比分析,给出不同情况下适宜采用的节点形式。分析了钢管混凝土柱初始受力状态、混凝土浇筑质量及收缩对节点刚度的影响,结果表明:这些因素对节点刚度的影响可达到20%,在节点设计中必须考虑。
four new type joints between concrete-filled steel tube columns and steel beams were put forward. Through the comparisons of stiffness, cracking degree, mechanical properties, economy, construction quality, etc., the paper proposed a suggestion of suitable joints under different conditions. The influences of the initial stress state of concrete-filled steel tube column, the quality of concrete pouring and the stiffness of the joints were analyzed, and the results showed that the influence could reach 20%, and it must be considered in the joints design.
