Create punching shear checks

You can apply punching shear checks to flat slabs and foundation mats by using the Add Check command on the Design tab.

Punching check locations

You can apply punching shear checks as follows:

In flat slabs:

  • Concrete columns supporting a flat slab with and without drops

  • Concrete columns supported by a flat slab

  • Concrete columns through a flat slab with or without drops

  • Concrete walls supporting a flat slab

  • Concrete walls supported by a flat slab

  • Concrete walls through a flat slab

  • Steel columns supported by a flat slab

  • Point loads at either face of a flat slab

In foundation mats:

  • Concrete columns supported by a foundation mat

  • Concrete walls supported by a foundation mat

  • Steel columns supported by a foundation mat

  • Point loads on a foundation mat

  • individual piles supporting a foundation mat

Punching check axis orientation

  • When you apply a punching shear check to a column, the check Y and Z axes are automatically orientated to align with the column major and minor axes. The two axis systems are locked together, so if the column is rotated, the punching check axes also rotate.

  • When you apply a punching shear check to a point load, you must manually define the punching shear check Z axis orientation. You can do this in the Properties window by specifying the point load orientation in relation to the global Y axis.

    Note: Point load properties (including point load orientation, point load breadth, and point load depth) are not applicable when you apply a check to a column.

Create punching check items

Note: Punching check items can generally be created in 2D and 3D Structural or Review Views, apart from checks around walls which can only be created in Structural Views, but not currently in Review Views.

Punching check items are the objects to which the punching shear information and calculations are attached. To create punching check items, do the following:

  1. On the Design tab, click Add Check.
  2. Go to the Properties window-
  3. Ensure that the location for the slab tension reinforcement is correct.
  4. Adjust the remaining properties according to your needs.
    Note: The point load properties are only relevant if you are adding the check to a point load position.
  5. To create the check, do one of the following:
    • Hover the mouse pointer over the desired column node, wall node, or point load. When the Pick Punching Check Location tooltip appears, click to add the punching shear at the selected node.
    • Hold down the left mouse button and drag a box to add punching check items to all potential check locations within the box.

Specify stud rail reinforcement

Restriction:

Stud rail reinforcement is only available for Eurocode and ACI head codes.

You can specify an orthogonal or circular arrangement of stud rails, and then check or design it as required.

  1. Create a punching check item as instructed above.
  2. Go to the Properties window.
  3. Select the Use reinforcement option.
  4. Select whether you want to autodesign the reinforcement.
  5. Adjust the remaining reinforcement properties according to your needs.

Modify the properties of existing punching check items

  1. Right-click the punching check item.
  2. In the context menu, select Edit Reinforcement.
