| Abstract: | 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. |

| Keywords: | parallel K-joint overlap tubular joints failure mode ultimate bearing capacity |
