Problems solved by technology

However, because the location of the spiral stirrup is concentrated on the edge and the number is small, it cannot make a sufficient contribution to the problem of axial compression ratio

Embodiment Construction

[0025] Such as figure 1 As shown, the densely packed spiral stirrup constrained concrete shear wall structure of a preferred embodiment of the present invention includes concrete 1 and spiral stirrups 2 uniformly distributed along the section of the concrete shear wall. Distributed reinforcing bars 3, horizontally distributed reinforcing bars 4, tie reinforcing bars 5 and longitudinal reinforcing bars arranged at the positions of constraining members on both sides of the spiral stirrup 2. The vertical spacing of the spiral stirrups 2 is 50-100mm. The spiral stirrups 2, the vertically distributed steel bars 3 and the horizontally distributed steel bars 4 form a double-layer distributed steel mesh in the wall. 2 to 6 times the spacing of the layer distribution reinforcement mesh, the distribution spacing of the vertical distribution reinforcement 3 and the horizontal distribution reinforcement 4 is 100-300mm, and the distribution spacing of the tie reinforcement 5 is 300-600mm. ...

Abstract

The invention discloses a densely-arrayed spiral stirrup confined concrete shear wall structure and a construction method of the densely-arrayed spiral stirrup confined concrete shear wall. The shear wall structure comprises concrete and spiral stirrups. The spiral stirrups are evenly distributed along the section of the concrete. Vertical distribution steel bars, horizontal distribution steel bars and pulling steel bars are arranged in front and back of the spiral stirrups. Longitudinal steel bars are arranged at the positions of edge confining components on the two sides of the spiral stirrups. Because the spiral stirrups are embedded into an ordinary reinforced concrete shear wall, the bearing capacity of the concrete is improved through the confining effect of the spiral stirrups, and accordingly the sectional dimension of the components, the self-weight of the structure and earthquake actions are reduced under the condition of same designed axial force.

Description

technical field [0001] The invention relates to a shear wall construction technology, in particular to a concrete shear wall structure constrained by densely arranged spiral stirrups and a construction method thereof. Background technique [0002] In recent years, with the continuous development of social economy and technology, the application of high-rise buildings in cities has become more and more extensive. The continuous increase in building height puts forward higher requirements on the seismic performance of the structure. Reinforced concrete shear walls, as vertical compression and key lateral force-resisting components in high-rise buildings, are the first line of defense against earthquakes, and their seismic performance, such as bearing capacity and ductility, is crucial to the seismic safety of structures. Especially in the case of high structures and large vertical loads, the section design of the shear wall is often controlled by the axial compression ratio r...
