Background
The high-rise steel structure building bears the constant vertical load and the lateral loads such as wind and earthquake, and transmits the internal force to the foundation through the pillar, and the connection between the pillar foot and the foundation is the key place. The internal force which needs to be transmitted by the column base comprises vertical pressure, pulling resistance, bending moment of the column bottom and the like. In the high-rise steel structure building design, the strong node coefficient of the column base is 1.35, and the column base is not expected to be damaged before other members under medium and large earthquakes.
The common methods for manufacturing the steel-structure column base include an embedded column base, an externally-wrapped column base and a flat-plate exposed column base. The outer wrapping column base occupies the space of a basement, and the bearing capacity of the flat plate exposed column base is limited and is mostly used for low stories. The embedded column base has the advantages of high bending resistance, high pulling resistance and bearing capacity, no occupation of basement space, convenience in underground parking and the like, and is a common column base node form.
In order to meet the requirement of a strong node, the embedded column base is designed by mainly considering the embedding capability of the foundation concrete to the column base. The specification stipulates that the embedded depth of the embedded column base in the foundation is not less than 2.5 times of the size of the section of the column, and structural measures such as column body studs, column base bottom plates, reinforcing steel bars around the column base and the like are added to jointly form a column base node with reliable stress performance.
For the raft foundation form commonly used in high-rise buildings, the embedded column feet are embedded in the foundation raft. Because the bottom layer column cross-section is great, the buried depth that the formula of buryying column foot required has the requirement of matcing to raft plate concrete's thickness, brings raft plate local thickening scheduling problem, has increased the cost of basis.
