The geometry and concrete class is defined by the user (Fig. 3-50).
The top band of the screen includes the geometry selection, as well as the definition of the characteristics of the concrete. The strength of the concrete can be either defined by using the characteristic (fck) or the mean compressive strength (fcm).
In the left area, the user inputs the data related to the geometry of the section, which is then displayed in the diagram located in the main screen.
The option “Rounded rectangle” or “Circular” can be selected to define the geometry of the column. Note that, in case of rectangular sections:
