Compared with the traditional reinforced concrete structure, the steel pipe can be used as a template, the construction period is shortened, materials are saved, and the steel pipe concrete structure has higher bearing capacity and ductility. The reinforcing mechanism of the steel pipe concrete lies in the advantages of mutual contribution and joint work between the steel pipe forming the steel pipe concrete and the core concrete, thereby greatly improving the overall bearing capacity and the ductility.
The steel tube concrete column generally divide into square steel tube concrete column, round steel tube concrete column, dysmorphism steel tube concrete column according to cross sectional shape, and wherein round steel tube concrete column has better constraint effect to the core concrete, can more fully play the bearing capacity of the pressurized of core concrete, and square steel tube concrete column then can overcome round steel tube concrete column because design, construction and the inconvenience in the use that cross sectional shape brought, and have that bending rigidity is big, the convenient advantage of nodal connection.
In the existing engineering application, in order to deal with the working environment with higher height, larger span and more variable stress, a steel pipe concrete structure with larger size needs to be designed and used, but the problems of difficult welding, higher manufacturing cost and the like in the construction process caused by the overlarge wall thickness of the steel pipe in the oversized steel pipe concrete need to be further researched for the application of the thin-wall steel pipe concrete. However, only reducing the wall thickness of the steel pipe results in reducing the steel content of the section of the steel pipe concrete, so that the constraint action of the steel pipe on the core concrete is weakened, and the bearing capacity, the seismic performance and the like of the steel pipe concrete are influenced.
The beam column node is used as a key part of a structure system, and the stress performance and the seismic performance of the concrete-filled steel tube composite structure are influenced. The common nodes are mainly divided into hinged nodes, semi-rigid connection nodes and rigid connection nodes according to rigidity and stress performance. The rigid connection node has higher rigidity and bearing capacity, and is widely applied in engineering. The common rigid connection node comprises a reinforcing ring type node, a stiff ring node and a shear ring beam node, wherein the reinforcing ring type node is mainly characterized in that a reinforcing ring is arranged at the upper part and the lower part of a beam end, the reinforcing ring is an outer reinforcing ring at the outer side of the steel pipe column, the reinforcing ring is an inner reinforcing ring at the inner side of the steel pipe column, the node can bear large bending moment and shearing force, and force transmission is clear. However, in the actual construction of the steel tube concrete external stiffening ring rigid joint, because the stiffening ring is in welded connection with the steel beam, the welding seams excessively increase the construction difficulty of the construction site, and the brittle failure of the structure is easily caused. The welding process is complicated and tedious in the construction of the super high-rise building structure, the construction progress is delayed, and more construction potential safety hazards exist. The assembly type bolt connecting node can reduce welding in a construction site, and components prefabricated in a factory are assembled on the site through bolt connection, so that the operation process is relatively simple, the construction speed is improved, and the performance requirement of a semi-rigid connection node can only be met by the general assembly type bolt connecting node.
