Post-earthquake recoverable functional framework system with additional lateral resistance energy consumption device

The invention relates to a post-earthquake recoverable functional framework system with an additional lateral resistance energy consumption device, and belongs to the field of structural engineering.The design concepts of damage control, replaceable energy dissipation elements, bending moment amplitude modulation, horizontal lateral separation resistance and the like are applied, and the advantages of a traditional rigid connecting column system and a traditional hinge column system are combined. A shape memory alloy is used as a material of a column bottom support, so that the joint stress performance is improved and the service life is prolonged. Through reasonable design, amplitude modulation of the bending moment is achieved, the bending moment on the column is reduced to protect thecolumn from being damaged, meanwhile, the replaceable lateral resistance energy consumption device bears main lateral resistance work, and damage to the joint is avoided in a strong joint mode. Afterthe earthquake, the anti-be
