All-hinged column end joint
The invention relates to an all-hinged column end joint, relates to a beam-column connecting member and aims to solve the problem that the use of rigid connection in the traditional beam-column connection will cause excess residual deformation after a bid earthquake or a medium earthquake, leading to the increase in post-earthquake maintenance and rebuilding cost. A joint area upper column and a joint area lower column are arranged face to face from top to bottom, a spherical face of a crown is disposed in a lower web semicircular cavity and a lower column internal reinforcing bar semicircular cavity, the lower end of a small ball is disposed inside the crown, the upper end of the small ball is disposed inside a bore of a hollow inverted four-sided pyramid, four cross beams are located on four sides of the joint area lower column, respectively, an upper flange of each cross beam is flush with the upper end face of the hollow inverted four-sided pyramid, the upper flange of each cross beam is connected with the joint area upper column through a steel angle and a connecting element, a lower flange of each cross beam is flush with the upper end face of the joint area lower column and is connected with the joint area lower column through a steel angle and a connecting element. The all-hinged column end joint is applicable to lateral resisting members in the field of building structural engineering.
