An intelligent shock absorbing structure for prefabricated frame shear wall

Abstract

A prefabricated frame shear wall intelligent shock absorption structure, including prefabricated beams, prefabricated columns, and shear walls. The prefabricated beams are arranged horizontally. The foam insulation material is filled between both sides of the shear wall and the prefabricated columns; the beam-column joint intelligent damping device is installed under the hinged structure, and the beam-column joint intelligent damping device includes the first pre-embedded body, the second pre-embedded body and the first piezoelectric ceramic; a prefabricated recycled concrete composite shear wall is installed under the shear wall, and the prefabricated recycled concrete composite shear wall includes a third pre-embedded body, a fourth pre-embedded body and a second piezoelectric ceramic. In the present invention, the controller adjusts the applied voltage of the 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, so as to realize real-time variation under the action of small and medium earthquakes. Friction and shear resistance; under the action of rare earthquakes, a large amount of seismic energy is consumed.

Description

technical field [0001] The invention relates to an intelligent damping structure of an assembled frame shear wall. 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 t...

Problems solved by technology

At present, for the research on the horizontal connection method of the prefabricated shear wall, the typical methods adopted are "sleeve grouting, anchor grout lap, extrusion sleeve", etc., but these connection methods are still difficult to make the prefabricated shear wall structure The internal force transmission path and constraints at the horizontal joints are exactly the same as those of the cast-in-place shear wall structure
