摘　　要：介绍了5个并联K形相贯搭接节点的试验情况,比较了试验和有限元分析的结果。以有限元分析软件为平台,研究了间隙率(搭接率)对K形节点破坏模式和极限承载力的影响,比较了并联K形和平面K形节点的受力性能,得到一些有益的结论。The experimental results of 5 full scale overlapped CHS K-joints subjected to axial load are compared with those of finite element models. Using the finite-element study as a platform, it is studied that the effect of laying rate on the failure mode and ultimate bearing capacity of the overlapped K-joints. Difference of mechanics capability between parallel K-joints and planar K-joints is also discussed. Finally, some useful conclusions are got.

关 键 词：并联K形节点 搭接 相贯节点 破坏模式 极限承载力
