Assembly type composite energy dissipation shear wall

Abstract

The invention relates to an assembly type composite energy dissipation shear wall. The assembly type composite energy dissipation shear wall comprises two shear wall components, a plurality of shock insulation supports are evenly arranged between the two shear wall components, one end of each shock insulation support is connected with one shear wall component, the other end of each shock insulation support is connected with the other shear wall component, at least one shape memory alloy rod piece is arranged between every two adjacent shock insulation supports, one end of each shape memory alloy rod piece is connected with one shear wall component through a rod piece connecting piece, and the other end of each shape memory alloy rod piece is connected with the other shear wall component through a rod piece connecting piece. According to the assembly type composite energy dissipation shear wall, the shock insulation supports and the shape memory alloy rod pieces are arranged between the two shear wall components, the overall ductility and energy dissipation capacity of the assembly type shear wall structure can be improved, the energy dissipation and shock absorption performance of a high-rise assembly type building is enhanced, and meanwhile, by utilizing the self-resetting characteristic of the shape memory alloy rod pieces, the shear wall components and the energy consumption device are reset after energy consumption.

Description

technical field [0001] The invention relates to the technical field of energy dissipation and shock absorption of building structures, in particular to an assembled composite energy dissipation shear wall. Background technique [0002] In recent years, the national construction management department has promoted the industrialization of construction in most parts of the country, that is, the promotion of prefabricated buildings, to meet the growing social needs by improving the efficiency of infrastructure construction. [0003] With the shortage of urban land resources, in order to improve the utilization rate of land resources, most of the buildings under construction or proposed are high-rise buildings. In order to meet the structural safety requirements of high-rise buildings, prefabricated buildings need to adopt prefabricated shear wall structures. However, the integrity, stiffness and deformation capacity of ordinary prefabricated shear walls are worse than those of ...

AI Technical Summary

Problems solved by technology

However, the integrity, stiffness and deformation capacity of ordinary prefabricated shear walls are worse than those of cast-in-place shear walls under the same conditions. The thickness of the shear wall, which not only increases the self-weight of the structure, but also does not necessarily show satisfactory seismic performance under actual earthquake action

In addition, the current shear walls with energy-consuming devices, because the energy-consuming devices are all pre-buried in the shear walls or installed in hidden parts, make the daily maintenance of the energy-consuming devices inconvenient, and the energy-consuming devices are After energy consumption, there will be residual deformation, and at the same time, the maintenance and replacement of energy-consuming devices are difficult or even impossible to repair. These are problems that need to be solved urgently
