Abstract
The utility model relates to a self-adapting stitch-separating shear wall belonging to the technical field of a concrete shear wall. The utility model is characterized in that the self-adapting stitch-separating shear wall comprises a reinforced concrete wall body and stitch-separating material; the stitch-separating material is vertically distributed at a stitch-separating position set in a wall sheet; the stitch-separating position is at least one vertical stitch appeared at the stitch-separating material and a concrete interface, and is increased following loads; and the stitch-separating material is plate material or thin-wall profile. The utility model remarkably improves the tensibility of the reinforced concrete wall body, and the brittle damage of a shear wall is changed into tensibility damage.
Description
Technical field
Self-adaptive parting shear wall belongs to the concrete shear force wall technical field, relates in particular to a kind of self-adaptive parting shear wall.
Background technology
Ordinary reinforced concrete shear wall ductility under geological process is relatively poor, brittle shear takes place easily destroy, and this is very unfavorable to integrally-built anti-seismic performance, and is also unfavorable to repairing after structure anti-collapse ability and the earthquake shake.The ductile fracture that realizes shear wall is an important channel of improving building structure aseismatic and the anti-safety stock that collapses cost-effectively, and ratio of shear span to effective depth of section is to influence the important parameter that shear wall destroys condition, and is relevant with the body of wall depth-width ratio.Not only depth-width ratio is difficult to avoid taking place shear failure less than 1 short shear wall in engineering practice, and depth-width ratio greater than 2 high shear wall because the interaction of member in the complexity of geological process and the structure, cause ratio of shear span to effective depth of section less, also the shear failure phenomenon can take place.For the shear wall of easy generation shear failure, improve the standard or vertical arrangement of reinforcement not obvious to the stress performance that improves body of wall, Chinese scholars has proposed various solutions for this reason, mainly contains band perps shear wall and steel reinforced concrete shear wall etc.
Self-adaptive parting shear wall is not increasing under the prerequisite of difficulty of construction and structural cost substantially, can significantly improve the stress performance of the shear wall of easy generation shear failure.Under the load action, self-adaptive parting shear wall experience evolution process from whole wall to band perps shear wall: load hour, shear wall is in elastic stage, shows as the mechanical characteristic of whole wall, rigidity is big; Along with load increases, body of wall is along steel sheet or light gauge cold-formed steel shape and the concrete perps that occurs at the interface, perps width, length is along with the increase of body of wall displacement increases gradually, the process of the carrying out difference of different parts perps, and perps has according to the stressed automatic appearance of body of wall and changes the characteristics of condition; After reaching the peak value bearing capacity, the length of perps tends towards stability, and body of wall is divided into a series of wall columns, thereby develops into band perps shear wall, non-linear hysteresis behavior by friction of perps both sides concrete and wall column end reinforcing bar comes dissipation energy, and ductility and energy dissipation capacity are good.In self-adaptive parting shear wall, potential perps place concrete becomes " fuse " of structure, can under big load action, ftracture automatically, the whole wall that ratio of shear span to effective depth of section is less changes the big wall column assembly of a series of ratio of shear span to effective depth of section into, brittle shear is destroyed the ductile fracture that changes the split wall into, wall ductility is significantly improved
Summary of the invention
The purpose of this utility model provides a kind of shear wall member with self-adaptive parting function, can improve the ductility of shear wall, improves its stress performance.
Of the present utility model being characterised in that contained reinforced concrete wall and barrier material, described barrier material is that the parting position of setting in described reinforced concrete wall is vertically arranged, described parting position is meant that described barrier material is sheet material or thin-wall section along with load increases in described reinforced concrete wall along described barrier material and concrete at least one perps that occurs at the interface.
Along with load increases, described self-adaptive parting shear wall can change the less whole cross section wall of ratio of shear span to effective depth of section into ratio of shear span to effective depth of section bigger wall column mixture, thereby has improved the ductility when body of wall destroys significantly.
Description of drawings
Fig. 1. the sectional view of the self-adaptive parting shear wall of preparation configuration section bar, 1 is the body of wall horizontal bar, and 2 is thin-wall section, and 3 are the vertical muscle of body of wall, and 4 is concrete.
Fig. 2. the sectional view of the self-adaptive parting shear wall of preparation configuration sheet material, 1 is the body of wall horizontal bar, and 3 are the vertical muscle of body of wall, and 4 is concrete, and 5 is sheet material.
The specific embodiment
Self-adaptive parting shear wall be in the ordinary reinforced concrete body of wall with certain spacing along the portrait configuration barrier material to separate concrete, realize the self-adaptive parting function.Barrier material comprises sheet material or thin-wall section; Sheet material can be metal sheet, fibre reinforced composites (being FRP) thin plate or high molecule plastic, and section bar can be cold bending thin wall shape, fiber reinforced composite section bars or high molecule plastic section bar etc.
In building course, self-adaptive parting shear wall and common shear wall construction technology are basic identical, only arrange barrier material at the position that needs parting.
