Description
Technical Field

Background
The steel pipe concrete has good mechanical property because the steel pipe can restrain the transverse deformation of the core concrete and the concrete can delay the buckling of the steel pipe on one hand, and on the other hand, the steel pipe concrete does not need a template during pouring, thereby improving the construction efficiency and reducing the construction cost. Therefore, the steel pipe concrete is increasingly widely applied to medium and high-rise buildings, industrial plants and bridge structures. The traditional rectangular steel tube concrete has a smaller constraint effect on core concrete than that of circular steel tube concrete due to the fact that the steel plate of the traditional rectangular steel tube concrete is smaller outside the plane. In order to improve the constraint effect of the rectangular steel pipe, the design specification of the composite structure in China requires that the height-width ratio of the section of the rectangular steel pipe concrete is not more than 2. In addition, since the steel pipe is thin, the steel pipe cannot be directly welded to the steel beam in order to prevent the steel pipe from being torn. At present, the main joint form of the main concrete-filled steel tube adopts two connection modes of an inner diaphragm plate and an inner diaphragm plate, and the joint structure and the construction are both complex.
