Abstract
The invention discloses a variable cross-section dual seismic shear wall system and a construction method thereof. In the structural system, the concept of a dual seismic system is adopted, and a reinforced concrete shear wall capable of bearing is arranged as a secondary structure based on using a reinforced concrete short-pier shear wall or a special-shaped column or a framework structure as a main structure. The main structure comprises proper bearing capacity and can bear a load independently; the secondary structure is in cooperative work with the main structure, and the secondary structure is destroyed and consumes energy firstly under the action of strong shock. No filling wall is arranged in the structural system and the main structure and the secondary structure have definite functions. Under the action of earthquake, the destruction is concentrated on the secondary structure, after the destruction, the structure has integrally reduced rigidity, the main structure can still bear a certain load with the gradually reduced action of the earthquake so as to avoid being destroyed, and repair work after the earthquake is mainly confined to the recovery of the function of the secondary structure, thereby the repair speed is fast, the cost is low, and the invention is a novel reinforced concrete shear wall system deserving popularization.
Description
Technical field
The present invention relates to a kind of reinforced concrete structure system and job practices thereof, specifically refer to a kind of variable cross-section reinforcement concrete shear wall system that twice provide fortification against earthquakes and its job practices of adopting.
Background technology
In the existing reinforced concrete shear wall system, all shear wall supporting capacitys are identical, do not have the branch of primary and secondary.This traditional earthquake resistant structure form far can not satisfy the increasingly high requirement of people to structure function to prevent collapsing, guarantee that life is target.The anti-seismic performance of traditional structure depends primarily on intensity, rigidity and the energy dissipation capacity of structure, has both required agent structure intensity high, requires ductility good again, is difficult to realize.Reinforced concrete shear wall structure intensity is high, rigidity is big, but ductility is less relatively, mainly is to rely on plastic strain hysteretic energy after its agent structure member surrender earthquake input energy that dissipates.The single earthquake resistant structure form of this agent structure and energy-dissipation structure one is though can realize the target of providing fortification against earthquakes of " middle shake can be repaiied, no collapsing with strong earthquake "; But shake back repair concentrates on the agent structure member, repairs difficulty, and supporting member is the power consumption member simultaneously; Bring many unmanageable problems to seismic design; Simultaneously, the indeterminate of structural seismic system causes power consumption position and structural damage form in the structure can not confirm in advance that all lateral resistant member are faced with identical danger.
And have the building block infilled wall in steel concrete shear wall with short piers, shaped rc columns or the frame construction, bring a lot of adverse influences for the antidetonation of structure.The vibration under geological process of the effect of restraint of infilled wall, rigidity effect and structure causes being with the infilled wall structure to have potential safety hazard under many circumstances to the influence of infilled wall.The effect of restraint of infilled wall is fairly obvious, possibly make shear wall with short piers become parapet, makes post become short column, and the ductility of member is reduced, and fragility increases.The vibration of structure under geological process might produce outside the plane infilled wall and destroys, and will cause personnel's injures and deaths and the carrying out that influences rescue work.In addition, infilled wall is easy to occur the crack, influences the normal use of structure.
And in general engineering, the shear wall with short piers steel using amount is very big, makes construction costs higher.The antidetonation grade of shear wall with short piers should improve one-level than the antidetonation grade of general shear wall, and its whole longitudinal steel ratios, and the position is strengthened in the bottom should not be less than 1%, and other positions should not be less than 0.8%; And the minimum steel ratio of general shear wall is 0.25% (one, two, three antidetonation).
Seek a kind of so new reinforced concrete shear wall antidetonation system and have significance of times: it can satisfy the requirement of people to safety of structure, can satisfy the requirement of people to structure function again.
Summary of the invention
The objective of the invention is to outside above several kinds of reinforced concrete shear wall antidetonation systems, provide a kind of new reinforced concrete shear wall antidetonation system and job practices thereof; This new structural system adopts twice to provide fortification against earthquakes; Combine the advantage of various shear wall structures, abandoned their shortcoming.
The objective of the invention is to realize through following technical scheme:
Adopt the notion of dual seismic system; With steel concrete shear wall with short piers (hetermorphiscal column or frame construction) but be on the basis of main structure load-bearing is set reinforced concrete shear wall as aggregated(particle) structure; The thickness of aggregated(particle) structure body of wall is littler than the thickness of main structure body of wall; Reinforcement ratio low (can by constructional reinforcement) is constructed with main structure.In such structural system, main structure has proper bearing capacity, can independently bear load; The aggregated(particle) structure body of wall is to the control of distortion, bearing capacity and the destructiveness of main structure under the different earthquake level and replenishes.Aggregated(particle) structure is set, can makes structure under little shake effect, have bigger rigidity and bearing capacity; And aggregated(particle) structure elder generation yield failure under severe earthquake action is consumed energy through sacrificing aggregated(particle) structure, with the protection main structure.The aggregated(particle) structure body of wall is made up of secondary member, destroys can not cause the damage of main structure, and is convenient to maintenance, replacement, reaches the requirement of safety and function.
The job practices of this variable cross-section dual seismic shear wall system comprises the steps: that (1) is when frame stands with assembling reinforcement; The reinforcing bar of main structure (steel concrete shear wall with short piers or hetermorphiscal column) and aggregated(particle) structure body of wall carries out simultaneously; But should carry out discretely; The main structure reinforcing bar is by design and construction, and aggregated(particle) structure reinforcement ratio main structure reinforcing bar is few, can be by the structure construction; (2) template of main structure with the aggregated(particle) structure body of wall installed; (3) main structure is built with the aggregated(particle) structure concrete.
Through above technical scheme, do not establish infilled wall in the variable cross-section dual seismic shear wall system, the primary and secondary structure function is clear and definite; Failure mechanism is clear; Destroy under the geological process and concentrate on aggregated(particle) structure, destroy back structural entity rigidity at aggregated(particle) structure and reduce, geological process reduces; And main structure can also be born a constant load, thereby avoids destroying.Shake back repair mainly is limited to the function of recovering aggregated(particle) structure, and reparation speed is fast, and expense is low.In addition, the design of main structure and aggregated(particle) structure body of wall is separable, makes design more easy.
