General Usage Instructions

You can use this plugin with or without a graphical interface. You have two commands:

  • CircularColoumn - Shows you a dialog for user input.
  • CIC- It will not show you a dialog box to enter the data

Whichever you choose, the program will perform the same actions.

The information entered must be in centimeters (CM) except for the diameters of the reinforcement bars. In this case you must use the number of the bar. It shows you a relation of the equivalences to inches.

  • The number of reinforcing bars in the longitudinal section should be equal to or greater than 5 pieces.
  • The spacing between reinforcing bars should not be greater than 15cm (150mm)
  • The minimum spacing should be equal to or greater than the diameter of the longitudinal reinforcing bar. 
  • The hook will be drawn at 135° with a development length described in ACI 304 25.32.
  • The separation of the stirrups should be greater than or equal to 15cm (150mm), this is an unnecessary data for the drawing process but it will be added to the labeling of the drawing
