Description
Technical field
The utility model is a kind of shear wall hidden with vertical soft steel energy consupting band, belongs to the structural engineering field.
Background technology
China is many earthquakes country, and building not only needs good building function, also needs to have good seismic resistance.Merely improve the shock resistance of structure, be difficult to satisfy the safety of structure and the requirement of applicability sometimes by the approach of " antiseismic firmly, reinforcement ".In recent years, people use for reference cybernetic method, by the approach of " defeating a force with a tenderness the damping power consumption ", adjust structural dynamic characteristic, reduce geological process, on this thought basis, have proposed a kind of new type of passive control Aseismic Structure System-band perps shear wall.
Band perps shear wall is made up of the continuous or discrete perps, wall limb, the tie-beam that connects left and right sides wall limb or the energy-dissipating device in linkage and the perps that are arranged in the shear wall body of wall.Under wind-force and normal service load effect, band perps shear wall is worked as common shear wall; Body of wall connecting portion generation plastic strain under the violent earthquake effect in the perps to reduce the rigidity of structure, reduces the natural frequency of structure, avoids the predominant period of seismic wave, reduces the seismic energy that structure absorbed; The body of wall connecting portion is when plastic strain is big under the violent earthquake effect, and the vertical burst of shear wall increases the depth-width ratio of body of wall, has had higher ductility, and shake is provided with defence line, second road in order to resist doughtily.Body of wall connecting portion in the perps can be provided with the energy dissipating control device, and the seismic energy that dissipates under geological process delays the process of agent structure member plastic strain.
Scheme commonly used at present has: the shear wall of being made of joint face between perps coupling beam, this form shear wall requires coupling beam to be in different crackings and yield situation in the different arrangement works stages, the shock-resistance features of competence exertion band perps shear wall, higher to designing requirement, and, the energy dissipation capacity of linking beam is limited, evidence, the coupling beam shear wall is under the violent earthquake effect, the concrete cracking and the crushing of shear wall bottom are comparatively obvious, mainly reduce geological process with the position plastic strain of shear wall base.
Have only reinforcing bar to form the shear wall of shearing joint face between perps, the bearing capacity of being cut of this form shear wall joint face is mainly provided by the dowel action of reinforcing bar, relies on the distortion of reinforcing bar and surrenders energy dissipating repeatedly, earthquake energy limited in one's ability.
The shear wall of forming joint face between perps by the rubber strip that passes through by reinforcing bar, the bearing capacity of being cut of this shear wall joint face mainly is made up of two parts: the rubbing action between the dowel action of reinforcing bar and concrete and rubber strip contact surface; Energy dissipating mainly contains three parts and forms: the distortion of reinforcing bar and viscoelastic strain, rubber strip and the concrete friction energy dissipating of surrender, rubber strip repeatedly.
In above-mentioned three kinds of shear walls between perps the rigidity of linkage interface the earthquake response of band perps shear wall is had considerable influence.Under the excessive situation of linkage interface rigidity, promptly the frictional strength on linking beam rigidity, rubber and the concrete interface is excessive, and total is worked as whole shear wall, and energy-dissipating device does not have the power consumption effect; On the contrary, if the rigidity of linkage interface is too small, band perps linking beam cracking and the frictional strength of destroying on too early or rubber and the concrete interface are very little, and the energy of dissipation also can be seldom.Therefore, having relatively high expectations in actual design process to linkage interface.
