Stair Properties, Stringers panel
The Stair Properties dialog, Stringers panel, is used to set or modify the stringer related property settings for a stair assembly.
Setting | Description |
---|---|
Stringer Base Offset |
Sets the distance from the finish floor to the stinger termination point. It provides a means for either extending or reducing the length of a stringer. For structural reasons, stringers may extend beyond the finish floor. Some stringers are encapsulated with concrete at the floor and the stringer needs to extend down to the floor structure instead of the floor surface. A positive number is up, a negative number is down. Finish floor = Base floor point + Base offset Stringers do not follow the convention of finish floor to finish floor used by tread and riser calculation using the Base Offset in the placement tab. |
Stringer Top Seat Offset |
Sets the distance from the finish floor to the stinger termination point. To connect to different structural system, the Stringer Top Offset only applies to the stringer calculation without affecting the riser/tread calculations. A positive number is up, a negative number is down. The Top Offset in the placement tab is used in riser calculations only provides a means for either extending or reducing the length of a stringer. |
Left / Right Stringer Type |
Sets the stringer type to the stair. |
Stringer Offset |
Sets the distance between the nose or foremost edge of the tread and the top of the stringer, measured perpendicular to the stair slope. Disabled when the Stringer type is set to OPEN. For a CLOSED stringer type, depending on the method used in stringer design, either one or both Stringer offset and Stringer Carriage offset are necessary. They are interrelated because the depth of stringer is controlled by our Stringer Section Profile. So if either the Nosing or Stringer Carriage Offset is set then the other value is the calculated results of the remaining distance. |
Stringer Profile |
Sets the stringer profile from the structural sections profile list. Opens Structural Sections filter list, where you can select one of the sections for a given code and type. The selected section profile's name is displayed in this text field.
|
Carriage Offset |
Sets the distance from the heel of the tread and/or riser to the bottom of the stringer measured perpendicularly to the stair slope. Stringer Offset and Stringer Carriage Offset are interrelated. Applicable to OPEN Stringer Type. |
Carriage Inset |
Sets the value that defines how far the open stringer is inset from the edge of the stair toward the walkline. |
Base Profile |
Sets the stringer base profile that defines the stringer base end condition and base connection. |
Base Seat Distance |
Sets the distance from the first nosing point of the first tread above the finish floor to the vertical cut plane for the stringer seat. Enabled when Top Profile is set to Seat, and applicable for both OPEN and CLOSED stringer types. |
Base Extension Type |
Sets Extension Type to a CLOSED Stringer Type.
|
Base Extension Distance |
Sets the distance in working unit for either the horizontal or vertical extension distance depending on the option selected in the Stringer Base Extension Type. |
Top Profile |
Defines the stringer top end condition and/or top connection. |
Top Seat Distance |
Sets the distance from the last nosing point of the last tread below the finish floor to the cut plane for the stringer seat. Applicable when Top Profile is set to Seat for both OPEN and CLOSED stringer types. |
Top Extension Type |
Sets Extension Type to a CLOSED Stringer Type.
|
Top Extension Distance |
Sets the distance in working units for either the horizontal or vertical extension distance depending on the option selected in the Stringer Top Extension Type. |
Top Trim Distance |
Sets the perpendicular distance from the finish floor to trim the top of the stringer. |
Stringer Part Definition |
Sets the stringer family and part pair through the popped up pull down menus. Family and part assignment could be done for straight/slanted panels as well as for plane and parametric profile risers. The value set through Part option overrides the native definitions of family part, if any in the profile. |
