Title: PREFABRICATED ENERGY-CONSUMING CONCRETE SHEAR WALL
Abstract:
A prefabricated energy-consuming concrete shear wall, comprising a reinforced concrete end wall (1) and a centralized energy-consuming area (2). The centralized energy-consuming area (2) comprises a reserved space and an energy-consuming area reinforce concrete unit; the energy-consuming area reinforce concrete unit comprises an energy-consuming concealed beam (8), or simultaneously comprises a concealed joint wall (9) or a cavity wall (10); the reserved space comprises a reserved transverse through joint (3), a reserved transverse concealed joint (4), and a reversed hole (5) or a reversed cavity (6); the reserved transverse through joint (3) and the reversed hole (5) run through the shear wall along the total thickness direction thereof; the reserved transverse concealed joint (4) and the reversed cavity (6) do not run through the shear wall along the total thickness direction thereof, and the reinforced concrete of a certain thickness is formed at two sides. By setting a transverse joint or a cavity inside a low reinforced shear wall, the ductility and the energy-consuming capability of the shear wall are improved, so that the whole anti-seismic performance of the structure is improved.
