Assembled frame shear wall intelligent earthquake absorption structure
The invention discloses an assembled frame shear wall intelligent earthquake absorption structure. The structure comprises a prefabricated beam, prefabricated columns and a shear wall, wherein the prefabricated beam is horizontally arranged, the two ends of the prefabricated beam are connected with the prefabricated columns through hinging structures, the prefabricated beam is arranged at the topof the shear wall, foam thermal insulation materials fills the space between each of the two sides of the shear wall and the corresponding prefabricated column, and a beam-column node intelligent earthquake absorption device is arranged below each hinging structure; the beam-column node intelligent earthquake absorption device comprises a first pre-embedded body, a second pre-embedded body and a first piezoelectric ceramic; and an assembled recycled concrete composite shear wall is arranged below the shear wall, and the assembled recycled concrete composite shear wall comprises a third pre-embedded body, a fourth pre-embedded body, and a second piezoelectric ceramic. According to the structure, a controller adjusts the voltages applied to the piezoelectric ceramics under the action of different earthquake loads, so that the rotation friction force and the sliding friction force of a core area are adjusted, the purpose of self-adaptation, to the earthquake response, of the whole structure is achieved, the real-time variable friction shear resistance under the action of moderate and small earthquakes is realized, and under the action of rare earthquakes, a large amount of earthquakeenergy is consumed.
