Stairs Ladders and Handrails Administrator Guide

Defaults : Create Default

To create a Default element make sure the correct Defaults Area is selected in the Defaults part of the SLH Administration Tasks window.

To create a Default element, from the Defaults part of the SLH Administration Tasks window, click Create next to the Defaults drop-down list to display the Create Defaults window.

Note:

All mandatory parts of the Create Defaults window are indicated with an amber triangle. The SLH application replaces the amber triangle with a green tick when the Create Defaults window has been populated with the required data.

General

The General part of the Create Defaults window displays by default, the administrator can name and describe the new Default element.


Name	Input a name for the new Default in the field (mandatory).
Description	The administrator can input a description into the optional field. If populated, the description displays in all windows that reference defaults, stair flights, handrails and rung ladders.
Function	The administrator can input a function into the optional field.
Name sub-elements	Select the check box for the SLH application to name new DDSE and DDAT elements by default.

Click Next to display the Constraints for Stair Flight part of the Create Defaults window. Refer to Stair Flight Constraints for further information.

Click Cancel to discard any inputs and return to the SLH Administration Tasks window.

Stair Flight Constraints

Constraints allow the administrator to specify the standard to be used for the stair flight and the default values. SLH checks to make sure that the default values are between the minimum and maximum values specified in the standard.

To remove the Stair Flight element from the Defaults, click to clear the Included check box.

Select a standard from the Use min/max values from standard drop-down list to specify the standard on which the defaults are to be based.

To visualise how the constraints equate to the stair flight, click Show diagram to display the Stair Flight Parameters window.

The Constraints list is populated with the minimum and maximum values from the selected standard.

By default, SLH populates each cell with the minimum column of the Constraints list with a minimum standard value or the maximum column of the Constraints list with a maximum standard value. Acceptable values input by the administrator into the cell of the Constraints list are highlighted in grey.

The administrator can input an explicit valid value into the Valid Value cell if the cell is not highlighted with a background colour.

If a value is entered and it is incorrect, an error message displays summarising the problem.

Use pitch formula rather than angle to calculate stair

By default, the stair flight is calculated from the angle, select the check box to calculate the stair flight from the pitch formula.

Allow intermediate landing

Select the check box to enable the user to define an intermediate landing for the stair flight, when the maximum number of rises is exceeded.

Selecting the Allow intermediate landing check box displays the Default Landing Thickness field.

Default Landing Thickness

Input a default value for the landing thickness in the field.

Allow cranked stringer

ONLY available when ‘To plane’ functionality is used.

Select the check box to enable the user to define a cranked stringer for the stair flight.

Extensions

Extensions are horizontal landings at the top and bottom of a stair flight.

Minimum Extension - default minimum extension.

Maximum Extension - default maximum extension.

Nosing Offset

ONLY available for selection in Detail.

The distance between the nose of the tread to the front edge of the stringer. This is measured from the nosing of the treads perpendicular to the front edge of the stringer.

The administrator can input a value into the optional field.

Allowable Configurations

Select the check boxes to enable the user to define a configuration for the stair flight.

Note:

At least one configuration between edges and one configuration for a plane must be selected.

The administrator can choose from:

•

No extensions

•
