Question 1
Error in column summary calculation: The calculation result of straight bar length is less than 0?
Method 1: Adjust to longitudinal reinforcement pin fixation, and calculate the reinforcement amount. However, there is a difference between setting steel dowel and longitudinal steel bar anchorage. You can manually add the calculated length when editing the reinforcement, or you can manually add it in the single-component input interface.
Method 2: If it is found that there is a relatively high foundation component intersecting with the column, such as a strip foundation, the strip foundation is saved with floor primitives, and the column is locked after normal calculation, and then the strip foundation is extracted with floor primitives.
Method 3: If it is a constructional column, calculate whether the masonry structure belongs to brick-concrete structure in the first project setting, if not, change it to Yes, and then summarize the calculation.
Method 4: Select Column-Brittleness-Reinforcement Business Attribute-Calculation Settings-Modify "Exposed Length of Longitudinal Reinforcement of Seismic Column" to 0.
Question 2
To sum up, why is the volume of columns in the report 0?
Method 1: Check the calculation formula of the column to see if the volume of the wall is deducted from the calculation formula.
Method 2: Check the engineering settings, calculate the deduction relationship between the column and the wall in the rules, and see if it is calculated according to the calculation rules of the column attached to the wall. If so, modify the corresponding calculation rules, as shown in the figure:
Method 3: The material in the column attribute is empty, which is caused by no choice.
Question 3:
How to identify the in-situ mark of light beam?
After the beam identification operation is completed and the bracket is adjusted correctly, click the beam identification-click the automatic identification in the inverted triangle, and the software will automatically identify it. After recognition, the check in-situ labeling window will pop up, and double-click the prompt to check whether recognition is needed. If you need to identify, you can click or manually enter it in the in-situ annotation. If it is not necessary to identify, it can be ignored.
Question 4:
What are constraint-edge concealed columns and structural-edge concealed columns, and how to deal with the support of shear walls in non-shadow areas other than XXmm concealed columns?
Definition of restrained edge and structural edge concealed column: "restrained edge concealed column" refers to a column restrained by stirrups, and its concrete is restrained by stirrups and has great deformation capacity. Edge concealed columns should be set at both ends of shear wall and both sides of hole, which can be divided into shadow area and non-shadow area.
"Structural side concealed column" is a kind of structural side concealed column which is relatively constrained by side concealed column, and has poor constraint on concrete. Only shaded areas, no non-shaded areas. See page11g1kloc-0/-1p 72 for details.
As shown in the figure, the edge hidden column is constrained, and the shadow area is an L-shaped hidden column with an inner side length of 300*300, and the non-shadow area is an I-shaped hidden column with an inner side length of 200 * 200 (one on each side of the L-shape).
Hidden columns of constrained edges and constructed edges are handled in the software:
Scheme 1: In the software, the unshaded area is usually defined as the section of the concealed column, that is, it and the concealed column itself are treated as concealed columns, and the reinforcement is drawn in the section editor of the concealed column.
Solution 2: Create a new parameterized column. In parametric drawing, select the last form of the corresponding shape, and input the size according to the drawing; Then, enter the corresponding reinforcement information in the attribute.
Solution 3: This part is directly calculated manually in the form input.
Question 5:
Why doesn't the attached column volume merge into the wall volume?
Reason 1: The column elevation is higher than the wall elevation, and only the intersecting part of the column attached to the wall is considered, and the non-intersecting part is considered and counted separately;
Reason 2: The concrete label of the column defined in the project is C35, but the concrete label of the concrete wall is C30. Check the calculation formula and measure the column volume. Now change the column concrete label to C30, and then summarize and calculate it again.
Reason 3: You need to look at the rule options. In some areas, the default columns and walls are calculated separately.
Reason 4: The material of the column is ready-mixed concrete, which can be cast in situ.
Question 6:
When drawing the civil air defense door frame wall, it is suggested that the civil air defense door frame wall must be arranged on the straight shear wall. Why?
Method 1: Use intelligent layout according to the midpoint of wall breakage.
Method 2: Because the elevation of civil air defense door frame wall is inconsistent with that of shear wall, the elevation of the bottom of civil air defense door frame wall can be changed to be consistent with that of shear wall.
Question 7:
How to select identity column details?
Step 1: After extracting column detail edge, column detail label and column detail reinforcement line, click Modeling-Identify Column Detail-Click Identify, click the CAD primitive of the column detail edge to be identified in the drawing area with the left mouse button, and the column detail information form will pop up, and the temporary primitive of column detail will be displayed in the selected cross section, as shown in the following figure:
Step 2: When the column details in the column details information form are perfect and confirmed to be correct, click OK button or right mouse button to close the information form and generate column members of the corresponding floor.
Question 8:
Is there a difference between the engineering quantity of the drawing input viewing component and the engineering quantity viewed in the report interface?
Reason: 20 18 software cannot refresh the report interface by calculating the number of selected elements separately, and can only refresh the report interface after calculating the whole building.
Method 1: After summarizing and calculating the whole building, the amount of viewing the drawing interface is the same as that of the report.
Method 2: Create a new blank project and merge it.
Question 9:
Why can't beams generate side longitudinal bars?
Reason 1: The web height is: beam height-plate thickness -BHC- stirrup diameter-(longitudinal bar diameter /2), which cannot be generated because it is misunderstood as beam height-plate thickness. Finally, the web height is recalculated and regenerated.
The second reason: the elevation of the plate is higher than the beam mark, and the beam is divided into two parts, so the software cannot judge the height of the diaphragm plate; The range of Liang Kuan is just the width of the beam, so it cannot be generated. The range of Liang Kuan needs to be greater than the width of the beam;
Reason three: the side length reinforcement of the beam has been input into the properties of the beam;
Reason 4: After clicking OK, there is no box to select the beam, so you need to box to select the beam and right click;
Reason 5: When the side reinforcement is generated from 20 18, enter 500~600 in the web height. The generation condition is that 500 does not include 600, so 499-600 is needed;
Reason 6: A beam is divided into many spans, and the information of steel bars in each span is different, some in two rows and some in one row. If the edge reinforcement is generated according to the height of the beam web, the value of the beam web height is different with different numbers of reinforcement, so some can generate edge reinforcement, and some can't, as shown in the following figure.
Reason 7: The beam did not identify the adjacent plates, and the condition was to deduct the plate thickness, so it was not generated.
Question 10:
How to incorporate the volume of concealed column into wall calculation?
In the project setting-calculation rules-deduction of embedded column volume and concrete wall volume, three embedded column volumes are selected to enter the wall volume, and three embedded column volumes are also selected for the deduction of concrete wall volume and embedded column.
