3.2.3 Punching Shear

Please follow the instructions provided below to perform Punching Shear Code Check.

Table 1: Punching Shear

1

Navigate to the "Punching Shear" section under "1st Floor" in the tree view.

In this section, click on the "Verify All" button.

Check if all columns are "Passed". If there is a column with "Failed" as shown in the figure, click on "Show" reports to investigate why the code check verification failed

According to the report, it has been noticed that the Top Reinforcement area is insufficient, so it is necessary to increase the reinforcement area.

Navigate to the "Flexural Reinforcement" tab in the same spreadsheet.

In this tab, click on the "Increase Top Reinforcement" button.

The Building Design Suite (BDS) will then add the Top Reinforcement Rebars to the reinforcement area as seen in the spreadsheet.

Then, Navigate again to the "Column Strip Reinforcements" section under "Top Reinforcements" from the tree view.

The rows are red because the "Provide Intensity" value is insufficient.

To correct this, increase the "Provide Intensity" value to be higher than the "Required Intensity" value for the rows marked in red.

This can be done by increasing the "Rebar" value or decreasing the "Spacing" value, or both processes can be applied at the same time.

When decreasing the "Spacing" value, the "Require Count" value will increase, thus, equalize the "Required Count" values with the currently available "Count of Rebars" values.

Navigate again to the "Punching Shear" section under "1st Floor" from the tree view.

Click on the "Verify All" button. Now all "Status" should be "Passed".

 

 

The “Punching Shear” part is completed in this step.

✓ 1st Floor Slab analysis of this Project has been completed.
