Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0038] In the first aspect, the embodiment of the present invention provides a method for designing a reinforced concrete beam-column structure, wherein the beam-column structure is as image 3 As shown, it includes: a first beam 1 , a second beam 2 , and a support column 3 , wherein the length of the first beam 1 is smaller than the length of the second beam 2 . The design methodology includes:

[0039] Step S1, obtaining the design reinforcement ratio of the first beam 1;

[0040] Step S2. When the design reinforcement ratio of the first beam 1 is greater than the maximum reinforcement ratio, increase the design width of the first beam 1 and reduce the Design height.

[0041] The principle of the reinforced concrete beam-column st...

Abstract

The invention discloses a design method of a reinforced concrete beam and column structure and the reinforced concrete beam and column structure, and relates to the technical field of reinforced concrete structures. The reinforced concrete beam and column structure comprises a first beam, second beams and supporting columns. The design method comprises the steps that the designed reinforcement rate of the first beam is obtained; and when the designed reinforcement rate of the first beam is larger than the maximum reinforcement rate, under the premise of guaranteeing that the sectional area ofthe first beam is unchanged, the designed width of the first beam is increased, and the designed height of the first beam is decreased. According to the design method provided by the invention, underthe condition of guaranteeing that the sectional area of the first beam is unchanged, the designed height of the first beam is decreased, and the designed width of the first beam is increased to decrease the reinforcement rate of the first beam; and increasing of the building material using quantity of the whole beam and column structure is avoided, increasing of the project cost is avoided, and meanwhile the clearance size of a building adopting the beam and column structure is further increased.

Description

technical field [0001] The invention relates to the technical field of reinforced concrete structures, in particular to a method for designing a reinforced concrete beam-column structure and a reinforced concrete beam-column structure. Background technique [0002] Reinforced concrete beam-column structure is one of the most widely used building structures. In the reinforced concrete beam-column structure, the ratio of the reinforcement area (that is, the sum of the cross-sectional area of ​​all steel bars in the beam or column) to the cross-sectional area of ​​the beam or column is called the reinforcement ratio, and the reinforced concrete ratio can be improved by adjusting the reinforcement ratio. The mechanical properties of the beam-column structure ensure the safety of the building. [0003] Related technologies provide a beam-column structure, such as figure 1 As shown, it includes: a first beam 1 , a second beam 2 , and a support column 3 . Wherein, both the first...
