Create Staircase

Stairs are used to provide access between different levels of the model. Defined as a series of stair flights and landings, the layout is controlled by the allowable going and rise of an applied standard.

The choice between concrete and steel is decided based on which Material element the stair is below.

To represent stairs, the application uses a number soft element types below a Group element.

• The Staircase act as a storage element.

• The Flight and Landing elements define the shape.

Referring to the hierarchy, a stair element must reside below an existing group element with a purpose set to Free.

From the Select Structural Element pane of the Building Applications window, make sure that the Group element is the CE.

The hierarchy in the Model Explorer is displayed as shown.

Below the Flight and Landing handrail elements there a number of Sub Component elements that can be created to represent additional features (for example: Plate, Hole, and Reservation and so on.). These can be found as SBFI elements below a PANE or FLOOR.

On the Building tab, in the Create group, select Concrete Staircase, Steel Staircase or Spiral Staircase in the Create Element drop-down list.

Click Create Element to display the Create Concrete Staircase window.

By default in the Naming pane of the Create Concrete Staircase window, the application automatically populates the Name field with a name based on the project or company autonaming rules. for further information on the autonaming rules, refer to Naming for further information.

The Use gaps in naming sequence checkbox is also selected by default, the user can select which auto name is to be used. To select the:

• first available name, click first available name.

• previous available name, click previous available name.

• next available name, click next available name.

• last available name, click last available name.

The user can change the name which does not conform to the autonaming rules, to do this, type a new name into the Name field. If this name already exists, an Error window is displayed. If the name does not conform with the autonaming rules, Apply remains greyed out as long as the name is not properly entered.

The Default Material drop-down list by default is set to Pyrocrete, the default material can be changed to another suitable material. From the Default Material drop-down list, the user can select from a list of suitable materials.

The material is used to calculate the weight. The density of the material selected is shown in a tooltip.

In the Assembly pane of the Create Concrete Staircase window, by default None is displayed. The user can add a selected assembly if required. Refer to Create Assemblies for further information.

Click Apply to create the Concrete Staircase element. The Modify Concrete Staircase window is displayed and the Concrete Staircase element is displayed in the Model Explorer and in the Building Applications window. Refer to Modify Concrete Staircase for further information.

To cancel the creation of the concrete staircase, click Dismiss. If the user navigates to another element, the window closes automatically.

Note:

It is also possible to create a staircase with AVEVA E3D Design using the Stairs, Ladders and Handrails application. On the Stairs Ladders and Handrails tab, in the Create group, click Stair Flight.
