Abstract

A prefabricated frame intelligent damping structure, including prefabricated beams and prefabricated columns, the prefabricated beams and prefabricated columns are connected by a hinged structure, and an intelligent damping device for beam-column joints is installed under the hinged structure; the intelligent damping device for beam-column joints includes The first pre-embedded body and the second pre-embedded body, one end of the first pre-embedded body is hingedly connected with one end of the second pre-embedded body, two first fan-shaped steel plates are arranged inside the first pre-embedded body; the second pre-embedded body A second fan-shaped steel plate is arranged on the inner side, and the second fan-shaped steel plate is arranged between two first fan-shaped steel plates; first high-strength bolts are arranged on the second fan-shaped steel plate; piezoelectric ceramics are arranged on one side of the first high-strength bolts, The electroceramic is connected with a controller. In the present invention, the controller adjusts the applied voltage of piezoelectric ceramics under different earthquake loads, thereby adjusting the rotational friction force and sliding friction force in the core area, so as to achieve the purpose of self-adaptive response of the whole structure to the earthquake, and realize the real-time change under the action of small and medium earthquakes. Frictional shear.

Description

technical field [0001] The invention relates to an assembled frame intelligent damping structure. Background technique [0002] In order to meet the increasingly diverse needs of architectural forms in modern society, the height and span of buildings continue to increase, so the coordinated development of structures and related design theories is required. The prefabricated structure has the advantages of fast construction speed, guaranteed component quality, and labor saving. It has been widely used in shopping malls, parking lots, middle and low-rise residences, hotels, etc. in New Zealand, Canada, Japan, and the United States. The specific structural types used include prefabricated frames, shear wall structures, and prefabricated prestressed structures. In order to adapt to the new situation of my country's economic development, prefabricated structures have developed rapidly. The country has formulated relevant policy documents and industry standards to promote the app...
