Steel-concrete with ultrahigh performance joint section and manufacturing method thereof

Abstract

The invention discloses a steel-concrete with ultrahigh performance joint section and a manufacturing method thereof. The steel-concrete with the ultrahigh performance joint section comprises a jointbeam, one end of the joint beam is connected with a steel beam, the other end of the joint beam is connected with a concrete beam, and the connection part between the joint beam and the steel beam isprovided with a bearing plate; according to the manufacturing method, the sectional dimensions of the steel beam and concrete beam, the length of the joint beam and the sectional dimension of the bearing plate are selected according to the design requirements; the steel-concrete with ultrahigh performance joint section and the manufacturing method thereof have the advantages that the problems of the complex structure, uneven stiffness transition, high construction difficulty and the like of the steel-concrete joint section can be solved, the structure is simple, and the steel-concrete joint section is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a steel-ultra-high-performance concrete joint section and a manufacturing method thereof. Background technique [0002] In steel-concrete hybrid bridges, in order to safely transfer huge loads between steel beams and concrete beams, it is necessary to install a large number of force-transmitting devices in the steel-ultra-high-performance concrete joint section, resulting in difficult construction of the joint section and structural problems. At the same time, due to the sudden change of section size, the stiffness is discontinuous, resulting in stress concentration of local components and poor driving comfort. SUMMARY OF THE INVENTION [0003] Aiming at the above-mentioned deficiencies of the prior art, the present invention provides a steel-ultrahigh-performance concrete joint section that is easy to implement and has smooth stiffness transition and a manufacturing ...

Problems solved by technology

[0002] In steel-concrete mixed structure bridges, in order to safely transmit huge loads between steel girders and concrete beams, it is necessary to install a large number of force transmission devices in the steel-ultra-high-performance concrete joint section, resulting in difficult construction of the joint section and structural problems. Reliability, at the same time, due to the sudden change in cross-sectional size, the rigidity is discontinuous, resulting in stress concentration of local components and poor driving comfort.
