• Rise height (vertical distance between the center lines of rungs) (A)

• Rung width (B)

• Rung extension width (C)

• Distance of the highest rung to the upper platform level (D)

• Max. height of the lowest rung from the floor level (E)

• Minimum distance from the wall to the center line of the stringers (F)

• Maximum distance from the wall to the center line of the stringers (G)

• Vertical distance from the center line of the lowest rung to the lower ends of the stringers (H)

  (H) is used only when stiffener connection type is selected during modeling.

Inserting the unit

1. Select the System.

2. Define the properties.

   

   • Connection type can be "Stiffener" or "Deck.

     In stiffener, connection type value (H) is used to determine where the stringers end.

     Deck connection is connected directly to the defined lower platform with a doubling plate.

   • Use double plates at the ends of the legs adds double plates to the end of the legs. This can be adjusted after selecting the points and directions for the ladder.

3. Select points and directions.

4. Define the legs.

   

   Edit Legs dialog enables the user to edit the height and length of each leg by typing the value or by clicking the Edit button to point the height or length from the model. Usage of doubling plates can be controlled for each leg individually by selecting "Use Doubler Plate".

5. Select a name for the structural unit.
