Abstract
Description
technical field
[0001] The invention belongs to the technical field of civil engineering, and in particular relates to a steel-concrete joint section used in a steel-concrete composite structure. Background technique
[0002] The steel-concrete bonded section is the key structure connecting the steel beam and the concrete beam. In the steel-concrete joint section, it is necessary to set up shear connectors to transmit the shear force to ensure that the steel beam and the concrete beam are jointly stressed. The PBL shear key is a commonly used shear connector, usually in the steel-concrete joint Arranged along the beam axis in the segment. Under the action of axial load, due to the axial deformation of the steel beam and the concrete beam itself, the axial load is mainly borne by the 3-5 rows of shear keys at the end of the steel-concrete joint section, and the load distribution of the shear keys presents two Correspondingly, the stress distribution of steel beams and concr...
