Punching
Use the Punching tool to define and manage punching shear checks on shell elements.
When you select Punching, a tool palette opens.
Main tools
- Define – define a new punching check on the selected shell element
- Properties – check or edit properties of an existing punching check. Opens the Default settings dialogue for the selected element
- Reset punching – remove calculated punching results for the selected element and restore the default state
- Default settings – set default parameters for new punching checks (read below in more detail)
Additional tools
- Column or point-like punching – activate the definition mode for column or point-like punching supports
- Wall end or corner punching – activate the definition mode for wall end or corner punching supports
Contour definition methods
Only available when Column or point-like punching is selected.
- Rectangular – draw a rectangular contour to define the column or support area
- Circular – draw a circular contour to define the column or support area
- Polygonal – draw a custom polygon to define the column or support area
- Pick lines – select lines from the model to define the shape of the column or support area
- Pick existing region – reuse an existing region's shape as the column or support area
Additional setting
- Downward – checkbox to set the default punching force direction as downward
Default settings dialogue
When you select the Default settings tool, a dialogue window opens.
- Identifier – text field for a user-defined identifier for the punching check
Orientation
- Downward – checkbox to set the punching force direction as downward
Design force calculation method
- Nodal force method, if applicable – checkbox to enable the nodal force method for calculating the design punching force when applicable
Shell internal force method
- Method – drop-down list to select the shell internal force calculation method. Available options:
- Integration, non-smoothed – calculate shell internal forces by integrating the stresses at the Gauss points without smoothing
- Max, smoothed – calculate shell internal forces by taking the maximum of the smoothed stresses at the Gauss points
- Max – calculate shell internal forces by taking the maximum of the stresses at the Gauss points without smoothing
- Distance of perimeter [d eff] – numeric field to set the distance of the control perimeter in units of effective depth
- Perimeter length limit [d eff] – numeric field to set the maximum limit for the perimeter length in units of effective depth
- End limit [d eff] – numeric field to set the end limit of the perimeter in units of effective depth
