The plastic failure stage is not entered under body displacement of targets, middle part is equipped with two 4-2 of through hole, needs to meet pressure transmission rod 3-1 oneself
By passing through.
It is of the present invention can optimizing stress distribution Self-resetting shear wall realization process it is as described below:
According to wall displacement of targets to wall, load transfer device (including: two 1-5 of one 1-4 of load transfer device and load transfer device) and
Flexible mat board (including: two 1-7 of one 1-6 of flexible mat board and flexible mat board) is designed, and chooses the concrete and steel of proper strength
Muscle is determined the length of pressure transmission rod 3-1, pulling force transmission lever 3-2 and outer tube 2-1 in load transfer device, to pressure
The position of transmitting key 2-2 and pulling force transmitting key 3-3 are determined.While assembling reinforcement, load transfer device and flexibility are arranged
Backing plate, and the inner wall oiling in the top surface of flexible mat board and outer tube 2-1, then casting concrete, branch mold forming.
Under normal operating condition, by reinforced concrete wall panel 1-1 and the common bearing structure vertical load of load transfer device,
Wall bottom section, wall internal force is by concrete and transmission rod shared.
When structure is by horizontal earthquake load, wall lateral deformation, side foundation compression side foundation tension.
In compression-side, for traditional shear wall, bottom section internal force is maximum, and concrete stress levels highest on section is cut
Face two sides concrete enters the plastic failure stage, and foundation conquassation occurs, and wall bottom goes out to cut with scissors, and wall is caused to produce during reciprocal transformation
Raw residual displacement.
For can optimizing stress distribution Self-resetting shear wall, the pressure transmission rod 3-1 in load transfer device undertakes a part
Force on cross-section does not enter the plastic failure stage, pressure transmission rod 3-1 is through outer tube so that concrete parts stress level reduces
2-1, then by pressure transmit key 2-2 by wall bottom section part endogenetic process in stress level originally lower wallboard on
Portion improves the stress level of the stress level also not high wallboard middle and upper part concrete when plastic failure occurs for wall originally,
And do not cause middle and upper part concrete destruction.
In tension side, for traditional shear wall, bottom section tension side concrete cracks under steel bar stretching effect,
It reduces the cementation of concrete and rebar, destroys the globality of foundation concrete, cause at foundation concrete in reciprocal mistake
It cracks and peels off in journey.
For can optimizing stress distribution Self-resetting shear wall, concrete is not by any pulling force effect, section at foundation
Pulling force is transmitted key 3-3 by pulling force and is acted on by the pressure transmission rod 3-1 and pulling force transmission lever 3-2 receiving in load transfer device
Concrete at foundation not tensile failure is protected on the low-down wallboard top of stress level.
See on the whole, can optimizing stress distribution Self-resetting shear wall in displacement of targets, the concrete of wallboard can be made
Stress distribution is more uniform (concrete stress levels reduce at foundation, and wallboard middle and upper part concrete stress levels improve), and
Not entering the plastic failure stage, wall occurs flexible deformation, does not accumulate Plastic Damage, residual displacement is not generated during reciprocal,
Wall can be achieved to reset.
When wall is more than displacement of targets, R.C. wall board enters the plastic failure stage, for conventional concrete shear wall,
Only largely plastic failure occurs for the concrete at foundation, and consumes energy, during wallboard failure, in addition to foundation
Other region concrete plastic failure does not occur.
For can optimizing stress distribution Self-resetting shear wall, the multizone of foundation and wallboard middle and upper part enters plasticity simultaneously
Failure stage, wallboard consumes energy, and region is bigger, and material use is more abundant.
Flexible mat board has the function of adjusting the distribution of foundation section concrete strain, in the case where the displacement of identical wall,
The foundation concrete of traditional shear wall enters the plastic failure stage, and foundation conquassation, wall bottom is caused to go out to cut with scissors.After placement of flexible backing plate,
Since the section rigidity of flexible mat board is less than the section rigidity of concrete, bigger deformation can be concentrated, concrete parts are reduced
Strain level increases foundation and destroys corresponding wall displacement, and shear wall has bigger elastic displacement stroke and ductility.
