文中异型高层钢结构在其下部柱的转折部位存在弯矩、轴力外荷载作用且受荷巨大,同时节点连接构造复杂,为解决梁柱连接构造以及保证节点的受力性能问题,在设计时采用了超大型的铸钢节点。对铸钢节点进行了有限元分析以及试验研究,结果表明试验结果与有限元分析结果接近,这对高层复杂梁柱连接节点设计中采用铸钢件提供一定的参考和借鉴作用,同时试验中25 000kN的加载也创下了国内建筑铸钢节点试验的加载记录。
In this paper, the irregular high-rise steel structure has bending moment and bending moment at the turning point of the lower column, which is subjected to a large load and an extremely complicated connection structure. In order to solve the beam-column connection structure and ensure the bearing capacity of the node, Uses a large cast steel node. The finite element analysis and experimental study of the cast steel joints are carried out. The results show that the test results are close to those of the finite element analysis. This provides a reference and reference for the steel castings used in the design of high-rise complex beam-column connections. In the meantime, 000kN load also hit a record of loading test of the domestic construction steel node.
