TR.32.9.2 Surface Selfweight Load

Used to calculate and apply the self weight of surface elements in the structure for analysis.

Note: This feature requires STAAD.Pro V8i (SELECTseries 3) or higher.

General Format

SSELFWEIGHT ( { X | Y | Z } f1) ( LIST surface-list | ALL )

Where:

Parameter	Description
X, Y, & Z	represent the global direction in which the selfweight acts. The default direction is along the Y axis.
f1	The factor to be used to multiply the selfweight. The default value is -1.0.
surface-list	surface element list or group. All list specifications such as explicit list including `TO` and `BY`, range (`XR`, `YR`, `ZR`), parallel to (X, Y, Z) and groups are supported. If a group is used, the selfweight command must be repeated for each group. If list is not provided, all structural components are used for body weight calculation unless those are inactive either by `INACTIVE` command specification or internally set due to TENSION/COMPRESSION ONLY specification.

See TR.32.9.1 Selfweight Loads for Description and Notes pertaining to self weight.
