Abstract
The invention relates to a shear wall with partial oblique steel bars, and belongs to the technical field of concrete shear walls. The shear wall is a concrete shear wall, and vertical-distributed steel bars arranged in the wall comprise oblique segments and vertical segments. The oblique segments of the vertical-distributed steel bars are crossed with horizontal construction joints of the shear wall obliquely. Force bearing capacity of the shear wall is improved, and horizontal shearing and sliding damages can be prevented.
Description
Technical field
The shear wall that configures local oblique reinforcing bar belongs to the concrete shear force wall technical field, relates in particular to a kind of shear wall that configures local oblique reinforcing bar.
Background technology
Under geological process, steel concrete is easy to along the living horizontal shear slippage changing of the relative positions of buying property of bending cracks or constuction joint equipotential, after the vertical muscle surrender in shear wall edge, horizontal shear sliding deformation shared ratio in total deformation increases gradually, cause the energy dissipation capacity of shear wall to reduce, unfavorable to structural seismic performance.When shear wall construction, the constuction joint place tends to the weak floor that exists one deck scum silica frost or poor concrete grout (being that coarse aggregate is many, cement mortar is less) to form, and shearing slip occurs while easily causing earthquake and destroy.Seimic disaster census has been found the sliding rupture phenomenon of shear wall.
In order to control the sliding deformation at body of wall bottom or constuction joint place, improve ductility and the energy dissipation capacity of shear wall, the shear wall of oblique reinforcing bar has appearred configuring.Eurocode 8(european norm) shearing (potential slide surface is 25% at other, for example the constuction joint position) that in, the regulation depth-width ratio is less than 2 shear wall bottom at least 50% is born by oblique reinforcing bar.But apparent, configuration oblique steel influential point of tendons brings certain difficulty to construction.
Summary of the invention
The objective of the invention is to improve the stress performance of shear wall, control the shear wall interlayer horizontal shear slippage changing of the relative positions, a kind of shear wall that configures local oblique reinforcing bar is provided.
The shear wall that the present invention configures local oblique reinforcing bar is concrete shear force wall, configuration level and vertical distribution reinforcement within the walls, and vertical distribution reinforcement forms by vertical section and oblique section, the oblique section potential level shear slip plane oblique with shear wall; The potential level shear slip plane refers under the horizontal reciprocating load action (under geological process), the position of body of wall occurred level shear strain, and for example, with the horizontal construction joint of body of wall, or every one deck body of wall floor top side location, particularly body of wall root.In order to prevent sliding rupture, oblique section of the vertical distribution reinforcement horizontal construction joint oblique with body of wall; Perhaps in the every one deck of shear wall, vertical distribution bar is comprised of vertical section of top and oblique section of bottom, oblique section at the bottom of this layer of wall with the floor level oblique.
The present invention compared with prior art has following advantage.
(1) can control the horizontal shear slippage of shear wall: oblique section of vertical distribution reinforcement with potential horizontal shear slide surface oblique, can effectively reduce the horizontal shear slippage, prevent shearing slip destruction.
(2) easy construction: vertical distribution reinforcement of the present invention comprises vertical section and potential slide surface position oblique section, and construction is more convenient than the shear wall of the oblique reinforcing bar of existing configuration.
The shear wall that configures local oblique reinforcing bar is applicable in shear wall structure or frame shear wall structure.
The accompanying drawing explanation
Fig. 1 is the shear wall schematic diagram of the local oblique reinforcing bar of configuration of the present invention; 1 is shear wall, and 2 is vertical distribution bar, and 3 is the potential slide surface of shear wall, and 4 is the horizontal distribution muscle, and 5 is floor.
Fig. 2 is the schematic cross-section in Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
In Fig. 1, the present invention configures the shear wall of local oblique reinforcing bar and is furnished with horizontal distribution reinforcing bar and vertical distribution reinforcement, in potential slide surface position (being floor epithelium constuction joint place in figure), vertical distribution bar bending certain angle (being generally 30 °-60 °), the bending part height is that 100mm-0.5H(H is This floor body of wall height).
The shear wall manufacturing process that the present invention configures local oblique reinforcing bar is as follows.
(1) arrange level and vertical reinforcement according to the job practices of ordinary concrete shear wall; In potential slide surface position, vertical reinforcement is 30 °-60 ° of certain-length scope inner bendings.
(2) formwork supporting plate, concreting, then maintenance, obtain the shear wall that configures local oblique reinforcing bar after form removal.
The shear wall and the common shear wall construction method that configure local oblique reinforcing bar are basic identical, only need potential slide surface position that vertical distribution bar is bent.
Claims (3)
1. configure the shear wall of local oblique reinforcing bar, this shear wall is concrete shear force wall, and configuration level and vertical distribution reinforcement, is characterized in that within the walls, vertical distribution reinforcement forms by vertical section and oblique section, oblique section of the described vertical distribution reinforcement potential level shear slip plane oblique with shear wall.
2. the shear wall of the local oblique reinforcing bar of configuration according to claim 1, is characterized in that, oblique section of the described vertical distribution reinforcement horizontal construction joint oblique with shear wall.
3. the shear wall of the local oblique reinforcing bar of configuration according to claim 1, is characterized in that, described vertical distribution reinforcement is comprised of vertical section of top and oblique section of bottom in the every one deck of shear wall.
