Abstract
The utility model relates to a steel reinforced concrete composite column. The steel reinforced concrete composite column comprises external crude synthetic fiber concrete and internal high-strength steel ribs, wherein inside of the composite column is not provided with longitudinal steel bars and transverse steel bars. The steel reinforced concrete composite column is characterized by being simple in structure and convenient to construct, comprehensively giving full play to the advantages of two materials to corporately resist external load effect, having good energy dissipation capacity, and being suitable for medium high-rise industrial and civil building structures in areas with seismic fortification intensity being at least 6 degrees.
Description
Technical field
The utility model relates to a kind of combination column with section steel and concrete, belongs to new builing structure system field.
Background technology
Steel-reinforced concrete structure has good anti-seismic performance, and this is verified in Japan great kanto earthquake in last century.After this, in this class formation Bian various countries' high level and super high rise building, be widely used.But in nineteen ninety-five the big earthquakes in Osaka and Kobe,Japan, find because of SRC post root, inner shaped steel weld strength is not enough, and the earthquake causing is much.In recent years, along with the material high strength of reinforced concrete structure and the develop rapidly of Super High technology, in addition SRC makes Building Design and constructional difficulties and the existence of the high investment that brings, the problem such as long in time limit, makes SRC make the construction ratio of building in whole construction market and is and reduces trend.In China, along with the development of economic fast and stable, society will produce a kind of lasting demand to building products.Meanwhile, the development of architectural structure system and design theory will meet the requirement of society to high-quality life, developing direction and the trend of just necessary paying attention architectural structure system.Along with the raising of urban life level, the restriction of environmental pollution, resource consumption is more and more tighter from now on; Therefore, guaranteeing under the prerequisite of shock resistance of the building reducing energy consumption and having the research of the new structure of active promoting function just to seem particularly important to the strategy of sustainable development.
Summary of the invention
The utility model has provided a kind of combination column with section steel and concrete, and described coupled column is only comprised of thick synthetic fiber concrete and high strength shaped steel reinforcing bar.On the one hand, thick mixing of synthetic fibers can obviously be improved concrete ductility, thereby the initial stiffness of retardance and constraint crack developing raising member also can alleviate the deformability that the degree of its accumulated damage improves member; On the other hand, high strength type hardness of steel is high, and under horizontal loads, high-strength shaped steel steel member hysteresis loop is full, has good energy dissipation capacity and anti-seismic performance and ultimate bearing capacity.The object of the invention is to form good resistance mechanisms by thick synthetic fiber concrete and the two collaborative work of high strength shaped steel, comprehensively bring into play the advantage of bi-material and jointly resist external loads effect.
the technical solution of the utility model is as follows:
A kind of combination column with section steel and concrete, comprise thick synthetic fiber concrete (2), high strength shaped steel reinforcing bar (1), it is characterized in that: thick synthetic fiber concrete (2) is wrapped in outside high strength shaped steel reinforcing bar (1), and longitudinal reinforcement and lateral tie are not set in described coupled column.
High strength shaped steel reinforcing bar (1) is the high strength shaped steel of yield strength standard value more than 460MPa.
In thick synthetic fiber concrete (2), the volume of thick synthetic fibers can be controlled in 6-13kg/m
3.
Compared with prior art, the present invention has the following advantages:
(1) high strength shaped steel forms good resistance mechanisms with thick the two collaborative work of synthetic fiber concrete, thereby the advantage of comprehensively bringing into play bi-material is jointly resisted external loads effect and made this novel combined earthquake-resistant structure possess good supporting capacity.
(2) thick mixing of synthetic fibers can obviously be improved concrete ductility, thereby retardance and constraint crack developing alleviate the deformability that the degree of member accumulated damage improves member.
(3) high strength shaped steel is applied in novel combined earthquake-resistant structure, the raising of China's building structural steel level will be helped lend some impetus to, in addition due to longitudinal reinforcement and lateral tie not being set, reduce the steel using amount of structure, contributed to develop green low-carbon, environmentally friendly structural system.
(4) simple structure, difficulty of construction little, there is very high superiority of effectiveness, be adapted at extensively promoting in engineering.
Accompanying drawing explanation
Accompanying drawing 1 is Novel combined column schematic cross-section.
In figure:
1-high strength shaped steel, 2-thick synthetic fiber concrete.
The specific embodiment
As shown in Figure 1, in this combination column with section steel and concrete, high strength shaped steel (1) adopts " H " shaped steel, and the volume of the thick synthetic fibers of thick synthetic fiber concrete (2) can be controlled in 7kg/m
3.
The combination column with section steel and concrete of the present embodiment is identical with embodiment 1, and difference is that high strength shaped steel (1) adopts "+" shaped steel, and the volume of the thick synthetic fibers of thick synthetic fiber concrete (2) can be controlled in 12kg/m
3, all the other are constructed with embodiment 1, are not described in detail in this.
Embodiment 3
The combination column with section steel and concrete of the present embodiment is identical with embodiment 1, and difference is that high strength shaped steel (1) adopts T-shape steel, and the volume of the thick synthetic fibers of thick synthetic fiber concrete (2) can be controlled in 9kg/m
3, all the other are constructed with embodiment 1, are not described in detail in this.
Be more than several exemplary embodiments of the present utility model, enforcement of the present utility model is not limited to this.
Claims (3)
1. a combination column with section steel and concrete, comprise thick synthetic fiber concrete (2), high strength shaped steel reinforcing bar (1), it is characterized in that: thick synthetic fiber concrete (2) is wrapped in outside high strength shaped steel reinforcing bar (1), and longitudinal reinforcement and lateral tie are not set in described coupled column.
2. a kind of combination column with section steel and concrete according to claim 1, is characterized in that: high strength shaped steel reinforcing bar (1) is the high strength shaped steel of yield strength standard value more than 460MPa.
3. a kind of combination column with section steel and concrete according to claim 1 and 2, is characterized in that: in thick synthetic fiber concrete (2), the volume of thick synthetic fibers can be controlled in 6-13kg/m
