Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model technology is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit utility model.
nullAs illustrated in fig. 1 and 2，The not through concrete power consumption partition wall that cracks of the few arrangement of reinforcement of a kind of communication type，Including concrete walls 1 and be arranged on the Vierendeel girder 2 around concrete walls 1 and frame column 3，Described concrete walls 1 can use low-grade concrete to be directly connected with Vierendeel girder 2 and frame column 3，Some perps 6 it are provided with in described concrete walls 1，Described concrete walls 1 are not provided with perps 6 with frame column 3 link position，The thickness of described concrete walls 1 less than frame column 3 in the 1/3 of corresponding wall thickness direction size，Described some perps 6 are along the arrangement of concrete walls 1 length direction and relative to the body of wall of the not through concrete walls 1 of concrete walls 1 short transverse，Wall stiffness can be reduced by the setting of not elongated perps and increase wall ductility and energy dissipation capacity，Described perps 6 is positioned at the centre position of concrete walls 1，The length of described perps 6 is not more than 1/2 that frame column 3 post of concrete walls 1 correspondence is high，On described perps 6、The spacing of lower end distance Vierendeel girder 2 is respectively greater than 1/4 that frame column 3 post of concrete walls 1 correspondence is high，The width of described perps 6 is 10～20mm，It is filled with flexible sealing material inside described perps 6，Vertical reinforcing bar 4 and horizontal reinforcement 5 it is provided with in described concrete walls 1，Described vertical reinforcing bar 4 two ends are anchored in Vierendeel girder 2，Described horizontal reinforcement 5 two ends are anchored in frame column 3.Described partition wall functions only as the compartment under construction, provides proper stiffness and undertake the effect of certain level load, does not undertake vertical load, therefore textural adopts Vierendeel girder, frame column reserved joint bar, after water the method for wall member.In body of wall, reinforcing bar functions only as the effect preventing from dodging down outside wall plane, can use C6 and C8 minor diameter reinforcing bar.
For preventing crack in the body of wall relatively early destroyed from diffusing into Vierendeel girder and frame column, perps should elongated setting, existing result of study shows, when perps length high less than frame column post 1/2 time, the crack that wall damage produces will not expand among Vierendeel girder；When thickness of wall body less than frame column when the 1/3 of wall thickness direction size, wall damage produce crack will not expand in the middle of frame column.Therefore, the length of perps in body of wall must be limited within frame column is high 1/2, and be positioned at the medium height position of body of wall；Body of wall wall thickness must be limited in frame column within the 1/3 of wall thickness direction size.
Wherein, body of wall between adjacent two perps 6 forms wall limb, each section of wall limb depth-width ratio between described perps 6 is more than 2, namely the gap ratio between the length of perps 6 with adjacent perps 6 is more than 2, it is all wall limb bent horizontal rigidity sums that full wafer opens concrete walls 1 horizontal rigidity of perps 6, described in open concrete walls 1 horizontal rigidity horizontal rigidity less than masonry partition wall of perps 6；In described concrete walls 1, vertically the arrangement of reinforcing bar 4 is monolayer distribution formula arrangement of reinforcement in full wafer body of wall, described vertical reinforcing bar 4 need not be arranged at every section of wall limb, described horizontal reinforcement 5 arrangement is monolayer distribution formula arrangement of reinforcement in full wafer body of wall, and vertical reinforcing bar 4 and the ratio of reinforcement of horizontal reinforcement 5 in described concrete walls 1 are 0.10～0.25%.
The force-mechanism changing wall stiffness and ductility by arranging perps is in that, if the back wall of seam becomes a series of wall limb, each section of wall limb depth-width ratio does not relatively set seam body of wall and all dramatically increases, so that the failure mode of body of wall destroys from the shearing-type of full wafer wall, the flexure type becoming each section of wall limb destroys, and therefore wall ductility increases along with the increase of every section of wall limb depth-width ratio.Body of wall initial stiffness is changed to all wall limb bent horizontal rigidity sums by shearing rigidity, therefore, it can control the horizontal rigidity value of body of wall by changing the quantity arranging perps, and the rigidity of full wafer body of wall reduces along with the increase of perps quantity.In order to ensure that each section of wall limb is all that flexure type destroys when undertaking horizontal loading, it is desirable to either segment wall limb depth-width ratio is more than 2.Simultaneously in order to ensure that few muscle cracks wall in the structure as partition wall work, abundant perps need to be set and make few muscle crack wall horizontal rigidity less than corresponding tradition masonry partition wall, can also consider as partition wall in Structure Calculation.
A small amount of arrangement of reinforcement is arranged in body of wall, result of the test shows, arranging under the premise of perps and a small amount of arrangement of reinforcement at body of wall, under the different ratios of reinforcement, few muscle opens the rigidity of perps wall, bearing capacity, energy dissipation capacity all closely, and to open the rigidity of perps wall, bearing capacity, energy dissipation capacity close with identical plain concrete.Illustrate that few muscle cracks wall mainly through the friction after concrete pressurized and concrete destruction, occlusion undertakes horizontal loading, and the seismic energy of the input that dissipates, the load that reinforcing bar self surrender undertakes is all very little with the ratio shared by energy of dissipation, therefore, a small amount of reinforcing bar functions only as the effect preventing from dodging down outside wall plane, do not play stress effect, therefore the ratio of reinforcement relatively can have bigger reduction by shear wall minimum steel ratio, the scope of desirable 0.10%～0.25%, form of reinforcement can adopt distributed arrangement of reinforcement, the through perps of horizontal bar, it is anchored among frame column, vertical bar is anchored in the middle of Vierendeel girder, full wafer wall can both be provided out of plane constraint with vertical bar by horizontal bar, one layer of steel mesh reinforcement is formed in the scope of full wafer wall, form of reinforcement is as shown in Figure 1.Owing to horizontal bar and vertical bar can both play the effect preventing dodging down outside full wafer wall plane respectively, therefore, there is no need to all arrange in each section of wall limb and be particularly well-suited to perps quantity more by vertical reinforcing bar, the situation that wall limb quantity is many and depth-width ratio is big.
Concrete result of the test:
For the low cyclic loading result of the test of the not through concrete power consumption partition wall that cracks of the few arrangement of reinforcement of 1:3 ratio communication type, the not through concrete power consumption ductility of partition wall, energy dissipation capacity and the damage-form of cracking of the few arrangement of reinforcement of communication type is described.
Fig. 3 shows the not through hysteresis loop cracked under concrete power consumption partition wall low cyclic loading of the few arrangement of reinforcement of communication type, visible, skeleton line slowly declines after reaching extreme point, illustrate that structure has good ductility, hysteresis loop area is full and stable, illustrates that structure has good energy dissipation capacity after destroying.By structure damage-form under 1/25 angle of displacement it can be seen that obvious plastic failure all occurs at upper and lower two ends in each section of wall limb after setting seam, form plastic hinge, illustrates that the damage-form of wall limb is flexure type destruction.Result of the test shows, the not through concrete power consumption partition wall that cracks of the few arrangement of reinforcement of communication type is by arranging perps, it is capable of each section of wall limb flexure type failure mode, thus realizing the controllability of wall stiffness, and increasing the ductility and energy consumption of body of wall so that the not through concrete power consumption partition wall that cracks of the few arrangement of reinforcement of communication type can become the first anti-vibration defense lines in frame structure before framework.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent replacement and improvement etc. made within spirit of the present utility model and principle, should be included within protection domain of the present utility model.
