Abstract

The invention provides an assembly type shear wall comprising a shear wall body, a first energy dissipation plate and a second energy dissipation plate. The first energy dissipation plate and the second energy dissipation plate are arranged on the two sides of the shear wall body correspondingly and each comprise a web plate and a flange which are mutually perpendicular. The web plates of the first energy dissipation plate and the second energy dissipation plate are embedded on the two sides inside the shear wall body correspondingly. Connecting holes are formed in the flanges of the first energy dissipation plate and the second energy dissipation plate. The adjacent shear wall bodies are fixedly connected through connecting pieces in matched connection with the connecting holes. Energy is consumed through a tension field formed by an energy dissipation device after buckling at a joint of the shear wall; on the one hand, structural ductility and deformation capacity are strengthened effectively, and the anti-seismic performance of the assembly type concrete shear wall is improved; and on the other hand, the shear wall body, the energy dissipation plate and the second energy dissipation plate are designed in advance and processed in a prefabricate mode, wet operation is not conducted on the site, and assembly operation is mainly conducted, so that the operation amount is small, the mounting efficiency is high, and the construction cost is low.

Description

technical field [0001] The invention relates to the technical field of assembled concrete structures in construction engineering, in particular to an assembled shear wall. Background technique [0002] The shear wall component is the main force-bearing component of the shear wall structure of high-rise buildings, and it is also the primary anti-seismic energy-dissipating component. The overall performance and seismic performance of prefabricated concrete shear wall structures depend on the strength, stiffness and ductility of prefabricated shear wall components. The structure and performance of the transverse connection at the vertical seam in the prefabricated shear wall directly determine the integrity, bearing capacity and deformation capacity of the shear wall component and its overall structure. [0003] At present, in the research project of NIST in the United States, the low-cycle repeated loading test research on the vertical joints of bolted joints and steel plate ...
