Traditionally, there are many types of connection nodes for the strong axis and weak axis of I-beam columns, but it is rare to connect the strong axis and weak axis in a node form. Usually, the strong axis uses one node form and the weak axis uses another node form for separate construction, which is an extremely cumbersome process. Summary of the invention
