摘要
为验证斜交网格钢管混凝土平面相贯节点的构造合理性和受力可靠性,设计了4个平面相贯节点试件,采用ABAQUAS有限元分析软件对节点构造、斜交角度和加载方式等的研究参数进行研究分析.结果表明:有限元模拟与试验研究在荷载—位移骨架曲线、荷载—应变曲线和承载力等方面具有较强的一致性,说明斜交网格钢管混凝土平面相贯节点的构造具有较好的合理性和较强的承载能力,可以应用到实际工程中.另外,不管是采用对称加载方式还是采用非对称加载方式,有限元模拟与试验结果比较接近,说明加载方式对试件受力和破坏影响不大.
In order to verify the structural rationality and reliability of concrete oblique intersecting concrete filled steel tubular（CFST）plane joints,four planar joints are designed.The ABAQUAS finite element analysis software is used to analyze the joint structure,skew angle and loading method and other research parameters of the study and analysis.The results show that the finite element simulation and experimental research have a strong consistency in the load-displacement skeleton curve,load-strain curve and bearing capacity.It is shown that the construction of concrete oblique intersecting concrete filled steel tubular（CFST）plane joints has good rationality and strong bearing capacity,which can be applied to practical engineering.In addition,whether using the symmetrical loading method or the asymmetric loading method,the finite element simulation is close to the experimental results,indicating that the loading method has little effect on the force and damage of the specimen.
