Post-earthquake recoverable functional frame supporting system with additional lateral-resisting energy consumption device

Abstract

The invention relates to a post-earthquake recoverable functional frame supporting system with an additional lateral-resisting energy consumption device, and belongs to the field of structural engineering. The design concepts of damage control, replaceable energy-consuming elements, bending moment amplitude modulation, vertical bearing and horizontal lateral-resisting separation and the like are applied, and the advantages of a traditional rigid connection column system and a traditional hinging column system are combined; a column bottom support is made of a shape memory alloy, thus the stress performance of joints is improved, and the service life is prolonged; through reasonable design, bending moment amplitude modulation is achieved, column bending moment is reduced to protect a columnagainst being damaged, meanwhile, the replaceable lateral-resisting energy consumption device bear main lateral-resisting work, and damage to the joints is avoided in a joint reinforcing mode; and after an earthquake, functions of the anti-bending hinged column foot frame supporting system can be recovered only by replacing the lateral-resisting energy consumption device.

Description

technical field [0001] This patent relates to a post-earthquake recoverable functional frame support system with an additional anti-side energy consumption device, which belongs to the technical field of structural engineering. Background technique [0002] Industrialized prefabricated steel structure is an inevitable trend in the development of high-rise steel structure residential buildings in the future, and it is the only way for my country to realize the industrialization of construction. Building assembly can standardize each component, the factory produces uniform specifications, and bolts are assembled accurately on site to avoid the consumption of building materials caused by construction errors, and compared with other structural forms, it reduces the weight and simplifies the design to reduce the cost; the project is highly organized , so that mechanized operations can replace manual labor to a large extent, and can reduce related costs. [0003] At present, ther...
