Stairs - Geometry

The Stairs - Geometry option defines the geometry and reinforcement of stairs. Select the option from:

• Menu: Reinforcement > Structure elements - reinforcement > Stairs
• Ribbon: ASD - Structure elements > Structure elements - reinforcement > Stairs
• Toolbar: Structure elements - reinforcement > Stairs .

The following dialog appears:

The top part of the dialog includes:

• Name of an RC structure element (stairs)
• Number of position
• Number of defined elements (stairs) - this number has an effect on the steel table
• Scheme of stairs; the following stair types are available (the number is entered into the Type edit field):
  1. stairs with two landings
  2. stairs with top landing
  3. stairs with bearers
• Width of the flight of stairs.

Select the Add element option to group the reinforcing bars (or reinforcing wire fabrics) of the stairs reinforcement into an element while generating the formwork / reinforcement of the stairs. The name specified in the Element name field is added on the Model tab of the Object Inspector dialog. The element (the group of reinforcing bars) displays in the Element manager dialog.

Once stairs' geometry is selected, dimension values are defined; a number of dimensions depends on a selected scheme of stairs. A schematic drawing of stairs adapts itself to the selected scheme.

In the schematic drawing of stairs, you can add a description of structural axes (by standard, letters A and B are entered - these values are editable) and the reference level (the level of left landing).

Note: If the fields with description of structural axes or the reference level are left blank, these parameters will not be generated in a drawing of the defined stairs.

After completing definition of stairs' dimensions, click Next, the Stairs - reinforcement dialog displays. Note: The contents of the dialog depends on the stairs' scheme selected.
