Abstract
The utility model provides a shear wall structure with an energy-consuming horizontal seam. The shear wall structure with the energy-consuming horizontal seam comprises a reinforced concrete shear wall, the horizontal seam, energy-dissipation shock-absorption devices, foot-portion steel plates, toggle pins, a packed layer and a foundation part. The horizontal seam is arranged in the reinforced concrete shear wall structure, and therefore deformation of the shear wall is concentrated at the position of the horizontal seam; the energy-dissipation shock-absorption devices are arranged at the position of the horizontal seam, when being pulled, the energy-dissipation shock-absorption devices move along with the pulling force, when being pressed, the energy-dissipation shock-absorption devices are not in a mode of buckling, and therefore the energy-dissipation shock-absorption devices present an energy-consuming property similar to a small-size anti-buckling anti-restraint support frame, and energy-consuming capacity of the shear wall is enhanced; the toggle pins are used to connecte the foot-portion steel plates with the foot portions of the shear wall to protect damage property of the foot portion of the shear wall on one side of the horizontal seam; and by means of the packed layer rigidity can not be provided, and meanwhile, the energy-dissipation shock-absorption devices are prevented from rusting. The shear wall structure with the energy-consuming horizontal seam is suitable for the condition that the earthquake fortification intensity is 6 degrees and more than 6 degrees. According to the shear wall structure with the energy-consuming horizontal seam, quake-proof conceptual design is clear, structure is simple, construction is convenient, material cost is low, hysteretic energy-consuming capacity is good, and compared with a traditional reinforced concrete shear wall structure, under the same large-deformation condition, damage to the shear wall structure with the energy-consuming horizontal seam is small.
Description
Technical field
The utility model relates to a kind of band power consumption horizontal joint shear wall structure, belongs to engineering structures antidetonation and energy-dissipating and shock-absorbing technical field.
Background technology
When earthquake took place, earthquake motion was passed to architectural structure system with the form of energy, and architectural structure system consumes the energy of earthquake motion input through nonlinear deformation and damage.The earthquake damage form of shear wall structure generally has flexure type destruction, the property sheared destruction; The earthquake of shear wall structure damage shows as concrete drawing crack, concrete crushing, reinforcing bar flexing, reinforcing bar and breaks etc.Earthquake damage form and performance by shear wall structure can be found out, damage after the shake of shear wall structure is repaired, and have sizable difficulty, thereby should actively develop the exploration to the power consumption of shear wall structure nonlinear deformation.In the shear wall bottom horizontal joint is set; Can be with the nonlinear deformation centralized Control in the horizontal joint place; Therefore if horizontal joint has good energy dissipation capacity; Then can reduce damage and reparation earthquake after of shear wall structure when earthquake effectively, but for realizing that earthquake restore funcitons shear wall structure is significant.
Summary of the invention
The purpose of the utility model is to provide a kind of band power consumption horizontal joint shear wall structure, through horizontal joint is set in shear wall structure deformation of wall is concentrated; The horizontal joint place adopts a kind of energy-consuming shock absorber to improve the energy dissipation capacity of shear wall; The horizontal joint side adopts peg to connect steel plate parcel shear wall foot raising damage performance; Filling elasticity packed layer prevents the energy-consuming shock absorber corrosion in the horizontal joint.The utility model is applicable to that seismic fortification intensity is 6 degree and above shear wall structure.The utility model conceptual Design of Earthquake Resistance is clear, structure construction simple, easy construction, and material therefor is with low cost, has good hysteretic energy ability, and more traditional reinforced concrete shear wall structure damage is little under identical large deformation condition.
A kind of band power consumption horizontal joint shear wall structure that the utility model proposes; Comprise reinforced concrete shear wall 1, energy-consuming shock absorber 2, packed layer 3, horizontal joint 4, peg 5, steel plate 6 and basis 7; Reinforced concrete shear wall 1 is positioned at basic 7 tops, is symmetrically arranged with horizontal joint 4 on the reinforced concrete shear wall 1 both sides bottom level direction; Horizontal joint 4 places are provided with the energy-consuming shock absorber of crossing over up and down 2, reinforcing bar welding in said energy-consuming shock absorber 2 one ends and the reinforced concrete shear wall 1, and other end connection is anchored in the basis 7; Horizontal joint 4 places, steel plate 6 wraps up reinforced concrete shear wall 1 foot through peg 5; Filling has packed layer 3 in the horizontal joint 4.
In the utility model, per pass horizontal joint 4 places are provided with a plurality of energy-consuming shock absorbers 2.
In the utility model, said energy-consuming shock absorber 2 is made up of low-yield mild steel reinforcement 2a and the common iron sleeve 2b that is placed in outside it.
In the utility model, the packing material that said packed layer (3) adopts is a rubber elastic material.
Compare with the reinforced concrete shear wall of general technology, the utility model has the advantages that:
(1) under normal mode of occupation, is with power consumption horizontal joint shear wall structure and is not with horizontal joint shear wall structure rigidity to be more or less the same.
(2) under geological process; The horizontal joint of shear wall structure opens and close up, and energy-consuming shock absorber can get into the hysteretic energy state quickly, surrendering appears when being drawn in this device, during pressurized not by lateral deflection; Thereby the energy-dissipating and shock-absorbing performance of shear wall structure is improved, and ductility also significantly improves.
(3) when displacement deformation was big, steel plate had been protected the compression damage of shear wall foot effectively.
(4) material therefor is with low cost, structure construction is simple, easy construction, and anti seismic efficiency is good.
