2. At this time, click linear to jump through the annotation in the menu bar.
<>4. In this way, the result of the diagram will be generated, and the size of the stirrup can be drawn.

Anonymous users2024-02-04Calculation method of rebar cutting length based on centerline length:
The cutting length of the rebar should be calculated according to the size of the component, the thickness of the concrete protective layer, the geometry of the rebar and the increase in the length of the rebar hook.
1. When it comes to the calculation of steel bar cutting, it generally involves the two concepts of "measurement difference" or "bending adjustment value". Generally, "measurement differences" or "bending adjustment values" for special angles are found in textbooks, but non-special angles, such as "measurement differences" or "bending adjustment values" for °, are not available in the existing literature.
2. The "bending adjustment value" or "measurement difference" on the relevant literature is obtained by taking the bending diameter = deduction. Nowadays, the bending diameter of longitudinal steel bending is not only limited, but also has the requirements of various bending diameters such as 12d and 16d, and the existing literature rarely considers this changed requirement.

First of all, you need to know the adjustment value of the stirrups, the adjustment value is the difference or sum of the two items of the increased length of the hook and the bending adjustment value.
1.The first thing to know is the adjustment value of the stirrups. 2.According to the measurement size of the stirrups with stupidity, the measurement method of Zheng Tong has different values. 3.The spacing between stirrups and stirrups should not be less than 20 cm.

Anonymous users2024-02-02The line reinforcement drawn by the line command must be thickened by the line reinforcement batch thickening command, and the reinforcement CAD system will automatically convert it into a composite line before it can be labeled with the reinforcement annotation tool, otherwise the software will not recognize it as a reinforcement.
The reinforcement CAD system provides the command to draw the point reinforcement, and the program is drawn by calling the donut command, which can save the file capacity, and the user can not draw the circle first, and then use the method of filling the circle to draw the point reinforcement, because the file capacity is large, and the reinforcement CAD system does not recognize this drawing method.
Stirrup features
The stirrups are used to meet the shear strength of the oblique section, and connect the reinforcement of the dust-carrying beam of the stressed main reinforcement and the mixed reinforcement skeleton in the Yinchun compression zone. It is divided into single-limb stirrups, open rectangular stirrups, closed rectangular stirrups, diamond stirrups, polygonal stirrups, tic-tac-toe stirrups and circular stirrups.
The stirrup made with a light round steel bar, its end should have a hook, and the bending inner diameter of the hook should be greater than the diameter of the stressed steel bar, and should not be less than the times of the stirrup diameter. For general structures, the bending angle of the stirrup hook should not be less than 90°, and the length of the straight part of the hook should not be less than 5 times the diameter of the stirrups.
For structural components with seismic fortification requirements, the joints of the circular stirrups must be welded, and the welding length should not be less than 10 times the stirrup diameter; The end of the rectangular stirrup should have a 135° hook, and the length of the straight part of the hook protruding into the core concrete should not be less than 20cm.

Anonymous users2024-02-01Ten stirrups refer to the number of stirrups of reinforced concrete beams, and the size of the stirrups is generally determined according to the design requirements and the size of the components. When drawing a stirrup diagram, you need to follow these steps:1
According to the design requirements and the size of the components, determine the position and number of stirrups. 2.Depending on the position of the stirrups and the number of stuffed plums, the position lines of the stirrups and the spacing dimensions of the stirrups are drawn in the longitudinal and transverse directions of the beam.
3.Draw the diameter and spacing of stirrups, usually using the ratio of stirrup diameter and spacing to determine the size of the stirrups. 4.
Draw the cross-sectional shape of the stirrups and how the stirrup ambush is connected to the main reinforcement, and annotate the relevant dimensions and quantities on the stirrups. It should be noted that when drawing the stirrup diagram, it is necessary to follow the relevant design specifications and standards to ensure that the size and spacing of the stirrups meet the design requirements, and to ensure the mechanical performance and safety of the components.
1. Calculation method of spiral stirrups: In cylindrical components (such as graphic columns, pipe strings, cast-in-place piles, etc.), the spiral stirrups are wound along the circumferential surface of the main reinforcement, and the length of the spiral stirrups per meter of steel skeleton length can be calculated as follows: >>>More
1.The encryption range is based on the specification, and there is no specific formula for calculating it. >>>More
Binding on it, why do you have to weld ah, one is a waste and the other is troublesome, there must be special circumstances to weld, in fact, they do not allow electric welding because the stirrup diameter becomes smaller or the diameter of the main reinforcement becomes smaller after welding, so that the force on the steel bar has an adverse effect.
Cover bar is often said to erect bar, structural bar. Generally speaking, the erection bar is used to erect stirrups in the beam, almost appear in the beam above the three limb hoops, that is, the ribs on both sides are passed, and the middle ribs only have additional ribs (that is, we say pick ribs), if there is no erection bar, the limb stirrups in the middle can not be tied, so there is a erection bar. General mechanics stipulates that the bending distance of the bottom tension of the lower side is the direction of the positive bending distance, so the top is the negative bending distance, and there is a negative bending moment at the end, so it is necessary to match the structural reinforcement, that is, the negative reinforcement, and the cover reinforcement. >>>More
The longitudinal reinforcement is what we usually call the stressed reinforcement, and the upper part of the support is generally tensile at the upper part of the support, and the lower part of the span is tensile at the middle and lower part; The stirrups are subjected to shear force, that is, the shear resistance of the oblique section; The name of the waist bar is derived from its location in the belly of the beam, which is mainly used for torsional resistance, of course, many cases are structured, in order to avoid the lack of reinforcement in a large area, and it is necessary to maintain a minimum reinforcement ratio; As the name suggests, the erection reinforcement is not forced, just the erection effect, for example, the stressed reinforcement at the top of your beam has 4 at the support position, the specification requires that the two must be penetrated, and the remaining two can be truncated in the appropriate position, so that there are only two reinforcements in the upper part of the span, if the stirrups are limb hoops, then the two limbs in the middle of the stirrups can not be supported, at this time it is necessary to increase the erection reinforcement of two structures, its diameter is smaller than the diameter of the stressed reinforcement at the bearing, erection reinforcement and truncation of the two lap joints, At this time, the stirrups have a bearing point, and the erection of steel bars plays this role!
