Description
Technical Field
The invention belongs to the technical field of building structures, and particularly relates to a high-strength longitudinal rib-based reinforcing rib column configuration component.
Background
As one of the most typical representatives of urban development, the field of construction engineering occupies and consumes most of social and natural resources, whereas the proportion of reinforced concrete structures applied in construction exceeds 50%. The use of reinforcing bars in large quantities is one of the main factors responsible for the consumption of resources and the degradation of the environment, and therefore, the development and application of high-strength reinforcing bars having a yield stress of more than 400MPa has been considered as one of the most effective ways to reduce the number of reinforcing bars and solve the above problems in practical engineering.
With the increasing demand for high strength steel, a great deal of research is being conducted in the industry on the component morphology and production process of hot rolled high strength steel bars. Although a series of mature manufacturing processes are formed for high-strength steel bars with yield stress exceeding 600MPa, the strength of the high-strength steel bars applied in the current engineering practice is still relatively conservative due to the limited regulations of the existing design specifications. For example, building code ACI 318 of the american concrete association limits the yield strength of steel bars to 550MPa. The CEB-FIP (european standardization institute) model specification specifies only the use requirements for rebars below 500 levels. Similarly, australian concrete structure standard AS 3600, although expanding the strength range of the rebar and introducing 600MPa rebar in 2018, has not preceded the use of higher strength high strength rebar. The domestic specification GB50010 provides a yield strength of even only 500MPa compared to the above-mentioned design specifications. Although the annual output of the domestic steel bars is the first in the world, the strength design of the high-strength steel bars applied in the domestic engineering practice is more conservative and is 300-400 MPa because the conventional design specification is limited; the strength of the steel bars adopted in the non-prestressed concrete structure is respectively 235MPa of yield strength, 335MPa of yield strength and 400MPa of yield strength as specified in GB50010-2002 of concrete structure design Specification and GB50011-2001 of building earthquake-resistant design Specification, wherein the use amount of the steel bars at the level of 400MPa only accounts for about 10% of the total use amount of the steel bars; the steel bars with the yield strength of 500MPa and above with higher strength are not listed in the specification at present, so that the proportion is not used as a reference when the situation is met. In view of the above, developing a proportioning data of a reinforcing rib column member suitable for high-strength steel bars, especially for high-strength steel bars above 600MPa, so as to promote the application range of the high-strength steel bars and fill the application blank of the type of steel bars is a technical problem to be solved in recent years.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a reinforcing rib column component based on high-strength longitudinal ribs, which can solve the problem of material proportioning of high-strength reinforcing ribs, and even can realize the construction purpose of a given beam column component by using lower reinforcing rib rate under the condition of the same column strength so as to achieve the effects of saving steel and component consumption and facilitating construction.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
Configuration strengthening rib post component based on high strength indulges muscle, its characterized in that: comprises a column body, stirrups and high-strength longitudinal bars which are arranged in the column body;
the ratio of the volume of the stirrup to the volume of the concrete in the column body is defined as a stirrup ratio beta, and the value of the stirrup ratio beta is obtained by the following formula:
Wherein:
a is a coefficient;
f c is the design value of the compressive strength of the column body;
k e is the shape factor;
f ty is the design value of the tensile strength of the stirrup;
The ratio of the volume of the high-strength longitudinal bars to the volume of the concrete in the column body is defined as a bar arrangement ratio gamma, and the value of the bar arrangement ratio gamma is obtained by the following formula:
Wherein:
a is the cross-sectional area of the column body;
f is the design value of the axial pressure bearing capacity of the column body.
Preferably, the value of the shape factor k e is as follows:
when the column body is a circular member, the shape factor k e is obtained by:
when the column body is a square member, the shape factor k e is obtained by:
Wherein:
d' is the diameter of the core region of the circular member;
b' is the diameter of the square member core region;
s is the stirrup spacing.
Preferably, the value of the coefficient a is:
When f c =9.6 MPa, a=1.53×10 -3; when f c =11.9 MPa, a=1.44×10 -3;
When f c =14.3 MPa, a=1.36×10 -3; when f c =16.7 MPa, a=1.28×10 -3;
When f c =19.1 MPa, a=1.21×10 -3; when f c =21.1 MPa, a=1.15×10 -3;
When f c =23.1 MPa, a=1.08×10 -3; when f c =25.3 MPa, a=1.02×10 -3;
When f c =27.5 MPa, a=9.7x10 -4; when f c =29.7 MPa, a=9.2×10 -4;
when f c =31.8 MPa, a=8.7x10 -4; when f c =33.8 MPa, a=8.1×10 -4;

The invention has the beneficial effects that:
1) When the reinforcing rib column component is actually designed, the stirrup is considered to be a high-strength steel bar, or the longitudinal bar is considered to be a high-strength steel bar. When the high-strength steel bar is a longitudinal bar, the strength of the whole reinforcing bar column member is improved relatively more, and the ductility is improved relatively less; when the high-strength steel bar is stirrup, the ductility of the whole reinforcing rib column member is improved relatively more, and the strength is improved relatively less. Of course, the above-mentioned improvement is only a relative concept, and the overall ductility and the overall strength of the structural member of the reinforcing rib column can be improved more than those of the conventional structural member, so that the overall construction effect can be ensured.
On the basis, the invention aims at the occasion of taking the longitudinal bars as the high-strength steel bars, thereby providing a set of simplified calculation thought aiming at reasonably calculating the material proportion and ensuring the maximum exertion of the self-strength performance of the high-strength steel bars. In the thinking, before the calculation of the high-strength longitudinal bars, the hoop matching ratio of the hoops is calculated in advance, and after the hoop matching ratio is definitely calculated, the corresponding bar matching ratio of the high-strength longitudinal bars is adaptively configured, so that the use requirement is finally met. The formula shows that the highest value of the hoop matching ratio and the reinforcement ratio is theoretically infinite, and is limited by the production cost, namely, the higher the hoop matching ratio and the reinforcement ratio, the cost naturally rises, and the highest value is limited according to the site construction cost. When in actual design, the beam column is considered to be as close to the lowest value or equal to the lowest value as possible, so that the construction purpose of the established beam column component can be realized by using lower reinforcement ratio under the same column strength, and the effects of saving steel and component consumption and facilitating construction are achieved.

The column body 10 may be a square member as shown in fig. 1 to 2 or a round member as shown in fig. 3. As can be seen from fig. 1 to 3, the stirrups 20 are circumferentially distributed along the column body 10, and the high-strength longitudinal ribs 30 are formed by extending axially along the column body 10.

F is the design value of the axial bearing capacity of the column body 10.
Example 1
In order to facilitate a further understanding of the present invention, one embodiment of the present invention is given herein in conjunction with the foregoing description as follows:
The column body 10 is made of concrete materials with a strength grade of C50 (namely, the compressive strength design value f c is 23.1 MPa), and stirrups 20 and high-strength longitudinal bars 30 are arranged in the column body 10. The high-strength longitudinal bars 30 are high-strength bars of 700 MPa.
The design value of the axial pressure bearing capacity of the reinforcing rib column member is f=1700 kN, the cross section is square and the size is 250mm×250mm, and the design value of the tensile strength of the stirrup 20 is F ty =545 MPa; the core area is 200mm by 200mm, and the stirrups 20 are spaced apart by 80mm.
The value of the coefficient a is obtained according to the table 1, and the value of k e is obtained by the calculation formula of the shape coefficient k e provided by the invention and is substituted into the calculation formula of the collar matching ratio beta:
The collar matching ratio beta is more than or equal to 0.97.
The invention provides a design method of column member reinforcement ratio gamma:
substituting to obtain the reinforcement ratio gamma of the steel bar with the ratio gamma of more than or equal to 1.48 percent.
For further verification, the column a (with a hoop ratio of 1.26%, i.e., greater than 0.97%) and the column B (with a hoop ratio of 0.67%, i.e., less than 0.97%) of the same brand of stirrups 20 together with the high-strength longitudinal bars 30 were subjected to test and finite element analysis respectively, to obtain a comparative graph of test data as shown in fig. 4. In fig. 4, the reinforcement ratio of the high-strength longitudinal bars 30 of the two columns is 1.48%, the concrete strength is 37MPa, and the results show that:
as can be seen from the load strain curve comparison chart of the test piece shown in FIG. 4, when the peak load is reached, the strain of the column A is increased by 29.5% compared with that of the column B, the bearing capacity of the column A is increased by 10.8% compared with that of the column B, and the aim of the established test is achieved. Meanwhile, it can be seen from the load-longitudinal bar strain curve comparison chart shown in fig. 5: when the test piece reaches the peak value, the strain of the column A longitudinal bar is obviously close to the yield strain of the 600MPa reinforcing bar, namely 0.003 place, which shows that the strength of the corresponding longitudinal bar is exerted and the bearing capacity is improved, and the high-strength longitudinal bar 30 of the column B is obviously not in a yield state.
