Abstract
Description
Technical Field
[0001] The utility model relates to a novel transition layer structure of a steel tube concrete column and a reinforced concrete column. Background Art
[0002] The combination of steel and concrete in steel tube concrete columns improves the rigidity of the steel tube and the compressive resistance of the concrete, thereby greatly improving the bearing capacity. The bearing capacity of reinforced concrete columns is generally lower than that of steel tube concrete columns, but it is more economical and the construction is relatively simple. If the lower columns of the structure are steel tube concrete columns and the upper columns of the structure are reinforced concrete columns, the bearing capacity of the lower columns can be improved while considering economy and ease of construction, providing technical support for the large hip structure.
