[0002] For the connection between the existing large-aperture variable-section circular pipe column and the box girder, it is usually a rigid connection node. The method of this node is to fabricate in sections in the factory and then go to the construction site for on-site butt welding to complete the connection between the box girder and the large-aperture variable-section circular pipe column. If the cross-sections of the box girder and the large-aperture variable-section circular pipe column are too large, it means that they are heavy and large in volume, resulting in large forces during construction and greatly increasing the docking difficulty. When using the traditional butt welding method for construction, the stress is relatively concentrated around the docking position, so it is easy to cause weld fissures, affecting the docking strength, and the on-site construction difficulty is large and the cycle is long.
