Abstract

The invention discloses a concrete shear wall with continuous annular steel bar structures. The concrete shear wall comprises a wall and a steel bar framework arranged in the wall, and is characterized in that the steel bar framework is composed of a transverse annular steel bar structure (1) and a longitudinal steel bar structure (2); The transverse annular steel bar structure (1) consists of multiple layers of continuously distributed steel bar rings; the steel bar rings in the same layer are connected into a whole by virtue of one or two transverse steel bars (3), so as to form the continuously distributed steel bar ring structures; the longitudinal steel bar structure (2) is composed of multiple longitudinal steel bars which penetrate in the steel bar ring structures and connected with the steel bar rings and the transverse steel bars (3); and at least one part of the longitudinal steel bars are positioned in the steel bar rings. According to the concrete shear wall, the transverse annular steel bars provide even lateral pressures for the core concrete of the shear wall, can provide operative constraint for the total cross section of the shear wall but not limited to the position of a boundary structure, simultaneously can provide operative constraint for the longitudinal steel bars, so that the longitudinal steel bars participate in compression resistance, the concrete of the shear wall is prevented from being subjected to premature crushing under a macroquake condition, the limit deformation capability of the shear wall is improved, and the ductility of the shear wall is enhanced.

Description

Technical field [0001] The invention relates to a shear wall, in particular to a concrete shear wall with a continuous ring-shaped steel bar structure. It belongs to the technical field of building structure. Background technique [0002] Spiral hoops have been used in columns for a long time, and they have shown excellent ductility and seismic resistance during major earthquakes. For example, in the Olive-View Hospital in the San Fernando Earthquake in 1971, the group buildings are ordinary hoop columns, and the bottom of the main building is spiral hoop columns. During the earthquake, the podium column concrete was completely crushed and destroyed, only relying on the support of the remaining spiral hoop columns, the upper part moved 600mm horizontally relative to the bottom of the first story column and still did not collapse. [0003] The traditional shear walls are relatively thin, so the distribution ribs are arranged in a straight line, and additional ties are set between ...
