Abstract

The utility model discloses an engineering fiber reinforced cementitious composites (ECC) shear wall. The ECC shear wall is integrally formed by a shear wall bottom, a plastic hinge area and a shear wall upper part; longitudinal reinforcing steel bars, stirrups, horizontal reinforcing steel bars, and vertical reinforcing steel bars are distributed in the shear wall; the concrete of the shear wall bottom and the shear wall upper part are common high-performance concrete; and the plastic hinge area is filled with ECC. In the ECC shear wall, the common high-performance concrete is replaced by the ECC at the plastic hinge area, so that the deformation capacity of the plastic hinge area of the high-performance concrete shear wall, and the shear capacity of the plastic hinge area of the shear wall are improved, and the plastic area of the high-performance concrete shear wall is effectively prevented from brittle failure; therefore, the earthquake resistant performance of the high-performance concrete shear wall can be improved obviously, and the high-performance concrete shear wall can be promoted to be popularized and applied in an earthquake area.

Description

A kind of ductility high performance concrete shear wall
Technical field
The utility model relates to the building structure aseismatic field, is specially a kind of ductility high performance concrete shear wall high-rise and super-high building structure opposing horizontal loading and vertical load that is used for.
Background technology
High performance concrete has advantages such as intensity height, mobile big, durability and anti-permeability performance are good, adapted to the modern project structure to stride greatly, towering, heavy duty develops and bear the needs of severe environmental conditions, is an important development direction of concrete technology.Reinforced concrete shear wall is a kind of lateral resisting structure member that is widely used in building construction.Adopt high performance concrete shear wall opposing horizontal loading and vertical load at the bottom of high level and super highrise building several layers, can reduce shear wall thickness, improve the usable floor area in house, have tangible economic benefit and social benefit.But,, make of the extensive use of this effective lateral resisting structure be restricted in the earthquake zone because the fragility and the deformability of shear wall own of high performance concrete shear wall are relatively poor.According to the loading characteristic and the earthquake experience of shear wall structure, the destruction of shear wall mainly concentrates on the bottom plastic hinge region under the geological process.Therefore, need seek the especially effective measures of deformability of a kind of anti-seismic performance of improving the high performance concrete shear wall, to satisfy the demand that the high performance concrete shear wall is applied in the high level of earthquake zone and super-high building structure.
Summary of the invention
At defective or deficiency that prior art exists, the purpose of this utility model is, a kind of ductility high performance concrete shear wall is provided.
In order to realize above-mentioned technical assignment, the utility model adopts following technical scheme:
A kind of ductility high performance concrete shear wall, this ductility high performance concrete shear wall constitutes one by shear wall bottom, plastic hinge region and shear wall top, inside is distributed with longitudinal reinforcement, stirrup, horizontal reinforcement, vertical reinforcement, it is characterized in that, the concrete on described shear wall bottom and shear wall top is common high performance concrete, and described plastic hinge region is the ductility high performance concrete.
Other characteristics of the present utility model are that described plastic hinge region is positioned at bottom the shear wall and in the middle of the shear wall top, it highly satisfies national Specification.
Ductility high performance concrete (ECC), ductility high performance concrete are disposed by a certain percentage by PVA fiber, industrial waste (flyash), clinker, fine sand and water and form.
Ductility high performance concrete shear wall of the present utility model can improve the anti-seismic performance and the plastic hinge region deformability of high performance concrete shear wall greatly, prevents that effectively shear wall plasticity suburb from brittle fracture taking place.The position is strengthened in the bottom that this shear wall is used for high level and super highrise building, can reduce the quantity of horizontal distribution reinforcing bar and restriction hoop in the shear wall, improves the whole anti-seismic performance and the anti-ability of collapsing of structure, thereby guarantees the safety of structure under big shake.
Description of drawings
Fig. 1 is the utility model adopts the ductility high performance concrete shear wall of ductility high performance concrete to plastic hinge region a schematic diagram.
Fig. 2 is that the A of Fig. 1 is to view.
The utility model is described in further detail below in conjunction with accompanying drawing.
The specific embodiment
Below with reference to Figure of description and embodiment the utility model is elaborated.
With reference to figure 1 and Fig. 2, the ductility high performance concrete shear wall that present embodiment provides constitutes one by shear wall base 1, plastic hinge region 2 and shear wall top 3, inside is distributed with longitudinal reinforcement, stirrup, horizontal reinforcement, vertical reinforcement, the concrete on shear wall base 1 and shear wall top 3 is common high performance concrete, and plastic hinge region 2 is the ductility high performance concrete.
Longitudinal reinforcement wherein, vertical distribution reinforcement should satisfy among the calculating of shear wall anti-bending bearing capacity and " Code for design of concrete structures " GB50010 constructs requirement.
Plastic hinge region 2 is positioned in the middle of shear wall base 1 and the shear wall top 3, and ductility high performance concrete (ECC) is disposed by a certain percentage by PVA fiber, industrial waste (flyash), clinker, fine sand and water and forms.
Build in the process, at first the shear wall base is built high performance concrete, directly pour into a mould the ductility high performance concrete to the plastic hinge region end face in plastic hinge region then, treat to continue to build the high performance concrete of shear wall superstructure after the initial set of ductility high performance concrete.
Be that principle of the present utility model is described below:
The utility model utilizes the ductility high performance concrete, has good plastic deformation ability and durability, can improve the fragility of high performance concrete self.Adopt the ductility high performance concrete in the stressed bigger plastic hinge region of shear wall, can significantly improve the anti-earthquake ductility and the plastic hinge region deformability of high performance concrete shear wall, thereby effectively alleviate earthquake shear wall member and integrally-built destructiveness.
The reinforcing bar of plastic hinge region horizontal distribution and stirrup should satisfy the requirement of being cut bearing capacity calculation, but need not satisfy the structure requirement of seismic design.
The regulation that the height of plastic hinge region is strengthened the position scope by national standard " seismic design provision in building code " GB50011 seismic structural wall, earthquake resistant wall bottom is taken.
