1, engineering information

Enter the structure type, fortification intensity and seismic grade according to the design instructions. Especially the input of calculation rules. According to the drawings for reinforcement atlas.

2. Calculation settings

The number of stirrups added at the junction of frame beam and non-frame beam should be 6 (see the drawing for details);

The main reinforcement with a diameter of 6 in the lacing configuration should be changed to 6.5;

Whether the negative reinforcement in the plate contains bearings should be modified according to the plate reinforcement diagram;

The layout and structure of shear wall, plate lacing and horse stool reinforcement should be arranged in two-way or plum blossom according to the drawings;

Distribution of steel bars in the slab: If the first-class steel bar with a diameter of 6 is used in the drawing, it should be changed to 6.5.

3, lap setting

Binding or electroslag pressure welding should be modified according to the structural design instructions.

4. Floor setting

Modify according to the construction drawing. In addition, the concrete grade of each member should be modified according to the structural drawing.

Second, drawing input.

1, axis

Draw the shaft network according to the floor plan of the building; If drawing requires an auxiliary grid, it should be drawn with two points, parallel points or point angles.

If a project has two independent grids and must be defined in an interface, you should use the point command to find the intersection of the two grids and draw them.

If the grid is complex, when you have to import CAD drawings, pay attention to whether the imported CAD size is consistent with the drawing size. If it is inconsistent, it needs to be revised.

2. Cylinders

Enter the drawing interface, and the software defaults to the first layer. If the graphic foundation has column members, you should switch to the foundation interface.

When drawing the foundation column component, the information of steel dowel should be changed according to the drawing details or structural description and other attributes in the column component attributes. Other floors do not need to be changed.

When the column component is drawn off-axis, you only need to select the column component and select the check and change label in the interface to modify it.

According to the positioning diagram of the column, the reinforcement information of the column member is input.

The constructional column can be intelligently arranged according to the information given in the structure description, and the information of intelligent arrangement should be modified according to the drawings. If the intelligent layout is troublesome, you can draw it according to the drawing method of the members in the above column.

Step 3: walls

Drawing of concealed column: The concealed column should be drawn first in the shear wall drawing, and the reinforcement information should be input according to the detailed drawing of shear wall. Generally, when defining hidden columns, parameterized hidden columns are preferred. If there is no corresponding pattern, special-shaped hidden columns should be selected.

Shear wall drawing: enter the reinforcement information of shear wall according to the detailed drawing of shear wall. When drawing, it should be noted that the end points of shear walls should include hidden columns. This is convenient for graphic calculation and drawing.

Masonry reinforcement: we don't need to set masonry reinforcement, and the software can only use the building area *0.6 (brick-concrete) or the building area * 1.4 (frame) for pricing.

4. Doors and windows

Doors: drawn according to the door and window table and the section of the architectural drawing.

Windows: drawn according to the door and window table and the section of the architectural drawing.

Coupling beam: define coupling beam, and just enter reinforcement information. Pay attention to the in-situ marking to identify the coupling beam.

Lintel: lintel generally exists on the upper side of doors and windows. In the structural design description, lintel information can only be defined according to the size and application position of lintel.

Step 5 light

1) define the beam member according to the beam construction drawing in the structural construction drawing; When defining, you only need to fill in the information marked in the beam concentration, and pay attention to the elevation of the beam.

2) For the information marked in situ, just click on the part to be marked and enter it. It should be noted that in case of changing the cross section, adding twisted steel bars or structural steel bars, you should input them in the lower steel bars, and click the index button to pop up the corresponding input information.

3) If the non-frame beam or short beam has no in-situ mark, we should also click on the in-situ mark to change the beam from pink to green, so that the beam can be identified.

4) When drawing, the part where the beam should be connected with the column member should be completely handed over.

5) During in-situ annotation, if the span number is inconsistent with the defined span number, click the drop-down button to recall the beam span. Increase or decrease support.

6) It is particularly important to note that when drawing, the position of the beam should be determined. For example, in the structural construction drawing, when we use the plane method of two-story beam to recognize the drawing, we should define the beam component at the first interface.

Cast-in-place slab:

1) Define plates according to their structural layout, and pay attention to how many kinds of plates are in the construction drawing. Change the name to the corresponding name when drawing, so as to check it later.

2) If there is reinforcement information of horse stool at the grass-roots level, it is necessary to input reinforcement information of horse stool.

3) Pay attention to the elevation of the board when drawing.

4) If the top floor is a sloping roof, three points should be used to define the function of the sloping plate. You can see the effect by applying dynamic observation.

Plate hole:

Generally used in the top floor, where there are holes. Just define it directly

Plate reinforcement:

1) Drawings of slab reinforced bars generally refer to bottom reinforcement, upper reinforcement, cross-slab reinforced bars (bearing reinforcement) and roof temperature reinforcement. Software refers to the bottom reinforcement, gluten and cross-plate stress reinforcement (load-bearing reinforcement) and roof temperature reinforcement.

2) The definition should be drawn according to the reinforcement diagram of the plate, and the name should be changed to: plate thickness+reinforcement information, which is convenient for later inspection. Gluten can be set by changing the category to gluten.

3) When drawing, first choose single board, multi-board or user-defined range (convenient to use according to the drawing). If there are only bottom steel bars, we only need to choose vertical or parallel to define them respectively. If it is a double-layer reinforcement, the corresponding method can be selected according to the actual situation.

4) Rectangular drawings or direct drawings are generally used to draw plates.

5) The length of the stressed steel bar across the slab does not need to be modified when it is defined, and can be re-entered when drawing.

Plate negative reinforcement:

1) The negative plate reinforcement in the construction drawing is called load-bearing reinforcement.

2) Definition of negative reinforcement of slab: the name only needs to define reinforcement information.

3) The negative reinforcement of the slab is generally drawn by drawing lines.

4) After drawing the negative reinforcement of the slab, you can use the command of viewing the reinforcement layout to check whether it is repeated.

7. Foundations

Foundation beam:

The drawing method of foundation beam is similar to that of beam, so I don't explain it. It is worth noting that the reinforcement information of the foundation beam is opposite to that of the beam. When defining, just don't enter mistakes.

Raft foundation:

1) the drawing method of raft foundation is similar to that of slab, and there are mainly two methods: straight line drawing and rectangular drawing.

2) If there is reinforcement information of the horse stool in the raft foundation, it should be input according to the reinforcement information of the horse stool given in the construction drawing.

3) After the raft is drawn, the raft will generally exceed the perimeter of the ground beam by a certain distance. If each edge exceeds the same distance, we can use the global offset in the offset command to draw. If each edge exceeds the same distance, we can use the multilateral offset in the offset command to draw.

Raft main reinforcement:

Similar to plate reinforcement, it is not explained here;

Raft negative reinforcement:

Similar to the plate negative reinforcement, it is not explained here;

Independent basis:

1) Detailed drawing of independent foundation shall be carefully observed before definition;

2) When defining, an independent foundation should be created, and on this basis, parametric independent foundation units are usually created. Then enter the corresponding size and reinforcement information.

Strip foundation:

The definition and drawing method of strip foundation are the same as that of independent foundation.

Pile cap:

The definition and drawing method of pile cap are the same as that of independent foundation, and the only notable thing is the form of reinforcement and the side reinforcement of pile cap (if any).

8. Others

It can be drawn directly according to the basic plan and detailed drawing (or it can be drawn by graphic calculation).

9, single component input

Single-component input generally includes a series of fragmentary reinforcement components such as stair reinforcement, balcony reinforcement and external angle radiation reinforcement. Among them, the reinforcement of stairs is modified by referring to the atlas and combining with the construction drawing, and other sporadic reinforcement needs to be calculated manually.

Third, other knowledge.

1. When drawing a standard floor, if the column components or other components of each floor are the same, we can copy the components into the floor.

2. When the same component exists on the same floor, we can adopt the method of mirroring and copying. If it is a beam member, we can choose to apply it to the beam with the same name;

3. When there is a slight deviation between the position of the drawing component and the drawing, the method of single alignment can be adopted to make the drawing component consistent with the drawing. When the component is not drawn to the position in the drawing, we can also use the method of moving or stretching to make the component consistent with the drawing.

4, all components need to pay attention to the elevation problem, should carefully observe the drawings, determine the elevation.

For more experience and skill summary of Guanglianda steel bar calculation software operation, please pay attention to the Wuhan Guanglianda training class of Boyi Education.

In the calculation setting of reinforcement software 2009, there are six options for the number of vertical reinforcement in shear wall, which are rounding+1, rounding up+1, rounding down+1, rounding up, rounding up and rounding down. How to correctly apply this setting to the actual project? Where is the shear wall for the same project? To understand this problem, we should avoid the software setting and start with the theory of manually calculating the number of vertical reinforced bars in shear walls. The determination of the number of vertical reinforced bars in shear wall is closely related to the restraint position of shear wall. I have been engaged in on-site construction management of steel bars for many years. To sum up, the number of vertical reinforced shear walls can be judged in three situations.

The first case; When both ends of the edge structure are unconstrained and completely at the free end, the number of elements is determined as follows.

The second situation; When one end has an unconstrained edge structure and the other end has a constrained edge structure, when the single end is at the free end, the number of roots is determined as follows.

The third situation; When both ends have a constrained edge structure and there is no free end at all, the number of roots is determined as follows.

How to manually calculate the number of vertical reinforced bars in shear wall under the above three conditions? In the era of computerization, how to calculate accurately in software? Now, under the 7 18 version module of Guanglianda 2009 steel bar, how to calculate and set the above three situations and share the following skills. If there is anything wrong, please criticize and correct the majority of senior users of Guanglianda.

When using software, you need to know the software settings, which operations are supported and which operations are not supported. Only when the engineering setting is correct can the engineering quantity be accurately calculated. For example, the calculation of the number of vertical steel bars in the above-mentioned shear wall can be set by the calculation method of the starting distance and the number of steel bars in the shear wall attribute setting. Before setting, you need to understand that the blue font in the attribute is a public attribute, and all components in the common category have this attribute, and they are linked to each other. This public attribute cannot be modified casually, but it is in black font in the settings, which is the private attribute of the component. Modifying this attribute will not involve the attributes of other components in the same category. In this way, the shear wall in the project can be defined according to different positions, and their properties can be modified respectively, and the quantities can be calculated according to their properties during summary calculation.

First of all, look at the first case, the setting of the full free-end shear wall with unconstrained ends, as shown in the figure below.

After setting, drawing, summarizing and calculating, the number of roots calculated by software is exactly the same as that calculated by hand. See below.

Look at the second case, the setting of a single free-end shear wall with one end constrained and one end unconstrained, as shown below.

After setting, drawing, summarizing and calculating, the number of roots calculated by software is exactly the same as that calculated by hand. See below.

In the third case, there are constraints at both ends and no free-end shear wall, as shown in the following figure.

In particular, the screenshot of the last picture has a rounding error. Thank you for reading the content of this post carefully, because there is no option to round to-1 in the software. After calculation and comparison of different sizes, round it down reasonably. The rounding in the screenshot is caused by an error. Because I didn't look at it carefully, the options in the screenshot didn't match the analysis, which caused you great confusion. I apologize here.

After setting, drawing, summarizing and calculating, the number of roots calculated by software is exactly the same as that calculated by hand. See below.

Summary: In the process of software calculation, private attributes take precedence over public attributes, which provides a convenient and quick channel for handling the setting of different attributes of the same category of components. For the same kind of shear wall in different positions, we can distinguish them by the member names, such as JLQ- 1 in the figure, which have the same properties in the figure, just because the positions are different. It is necessary to set and calculate the number of vertical steel bars separately, so JLQ- 1A, JLQ- 1B and JLQ- 1C are used to distinguish graphic elements.

In practical engineering construction, most shear walls have restrained concealed columns at both ends. Therefore, in general, in the engineering setting, the common attribute of shear wall should be set to the third category or above, and the default starting distance of S/2 of the software should be changed to S, and the default rounding up+1 of the vertical reinforcement quantity calculation software should be changed to rounding down. These two settings must be modified at the same time to ensure that the calculation results are consistent with manual calculation. For a few shear walls in different positions, the calculation results of the number of vertical steel bars in shear walls in different positions are modified by private attributes respectively. Finally, I hope that users will give more valuable comments on the above discussion, and I also hope that someone will have a better way to share with me and realize common learning and progress.

I believe that after the above introduction, everyone has a certain understanding of the summary of the operation experience and skills of Guanglianda steel bar calculation software. Welcome to Zhong Da for more information.
