Abstract

The invention discloses an assembly type frame intelligent damping structure. The intelligent damping structure comprises a prefabricated beam and prefabricated columns, wherein the prefabricated beamand the prefabricated columns are connected through hinge structures, beam column joint intelligent damping devices are installed below the hinge structures, the beam column joint intelligent dampingdevices comprise first embedded bodies and second embedded bodies, one ends of the first embedded bodies are hinged to one ends of the second embedded bodies, two first fan-shaped steel plates are arranged on the inner side of each first embedded body, a second fan-shaped steel plate is arranged on the inner side of each second embedded body, each second fan-shaped steel plate is arranged betweenthe two first fan-shaped steel plates, a first high-strength bolt is arranged on each second fan-shaped steel plate, a piezoelectric ceramic is arranged on one side of each first high-strength bolt,and the piezoelectric ceramics are connected with a controller. According to the intelligent damping structure, the controller adjusts the voltage of the piezoelectric ceramics under the action of different earthquake loads, so that the rotating friction force and the sliding friction force of the core area are adjusted, the purpose that the overall structure is self-adaptive to earthquake response is achieved, and real-time variable-friction shear resistance under the action of medium and small earthquakes is achieved.

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...

Examples

Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] see Figure 1-Figure 5 , a prefabricated frame intelligent damping structure provided by the present invention includes device one, a prefabricated beam 9, and a prefabricated column 10, wherein the prefabricated beam 9 and the prefabricated column 10 are connected by a hinged structure 11, and a beam column is installed under the hinged structure 11 Joint intelligent damping device 100; device one is an intelligent damping device for beam-column joints.

[0034] The beam-column joint intelligent damping device 100 includes a first embedded body 1 and a second embedded body 2, wherein the first embedded body 1 and the second embedded body 2 are rectangular structures, and the first embedded body 1 and the second embedded body 2 are high-strength steel plates with the same size as the hinged first embedded body 13 on the section of the prefabricated beam 9 and...
