Background
At present, along with the development of the construction industry, production workshops with high size and ultra-long span are more and more, and in a steel structure building, although the constructed bearing capacity is important, the node part is particularly important for the safety of the structure. In the column shoe of the steel structure, not the lower end of the column member but the lower end of the lowermost column member and the connection portion of the foundation concrete are referred to. The column foot effectively transmits the axial force, bending moment and shearing force borne by the lower end of the lowermost column to the foundation. The type in which the rigid nodes can be embedded, encased, exposed and buried in the whole assembly is called plug-in.
The existing mainstream foot injection construction mode is an embedded type, an embedded column foot is higher in fixation degree compared with other two column foot modes, and the bearing capacity is easier to ensure. If the steel column is designed to yield first, its restoring force characteristics exhibit stable full elastoplasticity. The length of the steel column in which the embedded column shoe is embedded in the foundation is increased, and the main beads within the width of the foundation beam cannot intersect with the inserted steel column and expand or bend into diagonal beads, etc., and the steel column shoe must be installed before the reinforcement of the foundation beam.
